question

how people reacted to cancer 50 years ago?

answer

-As recently as 50 years ago, a cancer diagnosis was typically a death sentence. Health professionals could only guess at the cause, and treatments were often as deadly as the disease itself. -Because we did not understand the disease process, fears about "catching cancer" from those who had it led to ostracism and bigotry-much like people with HIV were treated in the early days of the AIDS epidemic

question

what have dramatically improved the prognosis for most cancer patients?

answer

-knowledge of risks and symptoms, early detection, and significant developments in technology and treatment have dramatically improved the prognosis for most cancer patients, especially those who are diagnosed in the earliest stages of disease -we have also learned that there are many actions we can take individually and as a society to prevent cancer

question

what are important steps you can take yo reduce your risk of cancer?

answer

-understanding the facts about cancer -recognizing your own risk -taking action to reduce your risk

question

Cancer

answer

a large group of diseases characterized by the uncontrolled growth and spread of abnormal cells

question

unchecked, cancer cells _(what do to body?)

answer

impair vital functions of the body and lead to death

question

when something interrupts normal cell _, uncontrolled growth and abnormal cellular development results in a _

answer

-cell programming -neoplasm

question

neoplasm

answer

a new growth of tissue that serves no physiological function and results from uncontrolled, abnormal cellular development

question

this neoplasmic mass often forms a clump of cells known as _

answer

-tumor

question

tumor

answer

a neoplasmic mass that grows more rapidly than surrounding tissue

question

two types of tumors

answer

-malignant -benign

question

malignant

answer

question

benign

answer

-noncancerous -harmless; refers to a noncancerous tumor

question

most tumors are _

answer

benign

question

benign tumors are generally harmless unless they_

answer

-unless they grow to obstruct or crowd out normal tissues

question

hen a benign tumor become life threatening?

answer

a benign tumor of the brain, for instance, becomes life threatening when it grows enough to restrict blood flow and cause a stroke

question

The only way to determine whether a tumor is malignant is through _

answer

biopsy

question

biopsy

answer

-removal and examination of a tissue sample to determine if a cancer is present -removal and microscopic examination of a sample of cells

question

structure of benign tumors

answer

-benign tumors generally consist of ordinary-looking cells enclosed in a fibrous shell or capsule that prevents their spreading to other body areas

question

structure of malignant tumors

answer

-malignant tumors are usually not enclosed in a protective capsule and can therefore spread to other organs. This process is called metastasis

question

metastasis

answer

process by which cancer spread form one area to different areas of the body

question

metastasis process by malignant tumor make some forms of cancer particularly_

answer

-aggressive in their ability to overwhelm bodily defenses

question

by the time malignant tumors are diagnosed, malignant tumors have frequently_

answer

malignant tumors have frequently metastasized throughout the body, making treatment extremely difficult

question

how benign and malignant tumors are different from each other in how they spread?

answer

-unlike benign tumors, which merely expand to take over a given space, malignant cells invade surrounding tissue, emitting clawlike protrusions that disturb the RNA and DNA within normal cells

question

the disturption of DNA and RNA within normal cells by malignant cells, produces what kind of cells?

answer

-disrupting these substances, which control metabolism and reproduction, produces mutant cells that differ in form, quality, and function from normal cells

question

mutant cells

answer

-cells that differ in form, quality, or function from normal cells

question

what does it mean for a tumor to be malignant? (how determine if tumor is malignant?)

answer

-a malignant tumor is one whose cells are cancerous -malignant tumors are generally more dangerous than benign tumors because cancer cells divide quickly and can spread, or metastasize, from the original tumor to other parts of the body -Physicians usually order biopsies of tumors, in which sample cells are taken from the tumor and studied under a microscope to determine whether they are cancerous. Newer techniques, such as the minimally invasive "optical biopsy" allow microscopic examination of tissue without doing a physical biopsy

question

steps of metastasis

answer

1. Genetically altered skin cells 2. Cell divides more rapidly than normal 3. cells change form 4. In situ cancer: Cells stay in one place 5. Malignant tumor (cancer): cancer cells invade normal tissue and enter blood and lymph; metastases form at the distant sites

question

what causes a cancerous tumor?

answer

a mutation to the genetic material of a skin cell triggers abnormal cell division and changes cell formation, resulting in a cancerous tumor

question

situ cancer

answer

-if the tumor remains localized -cells stay in one place

question

cancer staging

answer

-a classification system that describes how far a person's disease has advanced -A numerical system with five stages is used to classify how far cancer has advanced within the body.

question

usually either through surgery or clinical or pathological analysis, it is possible to determine_(what about the cancer and how related to cancer staging)

answer

-to determine the size of the tumor, and how deeply it has penetrated, the number of lymph nodes that are affected, and the degree of metastasis or spread, known as the TNM (for tumor, node, and metastasis) system, of the disease -cancer are staged based on this variables

question

the most common known staging system assigns the numbers _to the disease

answer

-zero to four

question

cancer stage 0

answer

-early cancer, when abnormal cells remain only in the place they originated

question

cancer stage I; cancer stage II; cancer stage III (cancer stage 1 through 3)

answer

-higher numbers indicate more extensive disease -larger tumor size and/or spread beyond the organ in which it first developed to nearby lymph nodes and/or organs adjacent to the location of the primary tumor

question

cancer stage IV (4)

answer

-cancer has spread to other organs

question

why cancer staging is important?

answer

-staging is important because it helps doctors and patients decide on appropriate treatments and estimate a person's life expectancy

question

what are 2 causes of cancer?

answer

-causes are generally divided into two categories of risk factors: hereditary and acquired (environmental)

question

how hereditary factors differ from environmental factors?

answer

-hereditary factors cannot be changed, but environmental factors are potentially modifiable

question

environmental factors include

answer

-include the physical environment and personal lifestyle habits and conditions such as tobacco use, quality of nutrition, physical inactivity, obesity, certain infectious agents, certain medical treatments, drug and alcohol consumption, excessive sun exposure, and exposure to carcinogens, such as pollutants in the food, water, and air

question

epithelial tissues (tissues covering body surfaces and lining most body cavities), which are part of carcinomas

question

carcinomas (what they take into account, how common, how metastasize, type of tumors)

answer

-cancers occurring in epithelial tissue are called carcinomas -epithelial tissues (tissues covering body surfaces and lining most body cavities) are the most common sites for cancer -these cancers affect the outer layer of the skin and mouth as well as the mucous membranes. -They metastasize through the circulatory or lymphatic system initially and form solid tumors

-it is never to late to quit. Stopping smoking at any time will reduce your risk of lung cancer, in addition to the numerous other health benefits that are gained. Studies of women show that within 5 years of quitting, their risk of death from lung cancer decreases by 21%, compared to people who continue smoking

question

Risk factors for lung cancer

answer

-risks for cancer increase dramatically based on the quantity of cigarettes smoked and the number of years smoked, often referred to as "pack years" -people who have been exposed to industrial substances such as arsenic and asbestos or radiation are at higher risk for lung cancer -exposure to both secondhand cigarette smoke and radon gas (a gas that leaks into houses from naturally occurring uranium in the soil) is believed to play an important role in lung cancer development for smokers, past smokers, and people who have never been smokers

-although incidence rates of breast cancer declined by about 7% between 2002 and 2003, newer research indicates that these declines did not continue between 2003 and 2007, even though hormone use declined significantly -in fact, although there was little change in rates for most groups, incidence rates increased for certain types of breast cancer in those age 40 to 49, although further study is necessary

question

lifetime risk of women to be diagnosed with breast cancer?how this risk changes with age?

answer

-women have a 1 in 8 lifetime risk of being diagnosed with breast cancer -From birth to age 39, the risk is 1 in 203, but between the ages of 40 to 59, the chance for breast cancer falls becomes 1 in 27

question

most health groups have advocated screening for breast cancer more thoroughly after age _

answer

40

question

what are 3 methods of detection of breast cancer?

answer

-mammograms -regular breast self-examination (BSE) -magnetic resonance imaging (MRI) -recently approved by FDA, 3D mammogram machines

question

mammograms

answer

-the earliest signs of breast cancer are usually observable on mammograms, often before lumps can be felt -mammograms detect 80 to 90% of breast cancers in women without symptoms

question

what is the problem with mammograms? solution?

answer

-However, mammograms are not foolproof, and there is debate regarding the optimal age at which women should start regularly receiving them -hence, regular breast self-examination (BSE) is also important

question

what is the newer detection method of breast cancer? what kind of women want to use it?

answer

-a newer form of magnetic resonance imaging (MRI) appears to be even more accurate, particularly in women with genetic risks for tumors

question

what is the age recommended to take mammograms as stated by US preventive services task force? why?what critics believe?

answer

-U.S. Preventive Services Task Force (USPSTF), made up of experts across the country, suggested that women should not have a mammogram until they are 50 and then have one only every other year -while evidence shows that women aged 50 to 74 seem to benefit from mammograms, similar benefits for women under age 40 appeared to be much less apparent -critics argued that USPSTF recommendations were politically and economically motivated and did not consider all of the facts. some believe to have mammography screening for women between the ages of 40 and 50 *pros and cons found in page 506*

question

the _has one of the highest breast cancer rates in the world

answer

-The United States (US)

question

what genes contribute to breast cancer?

answer

-BRCA1 -BRCA2

question

breast-self-exam has been recommended _

answer

-by major health organizations of early breast cancer screening for the last two decades

question

what 2009 "study of studies" done by US preventive service task force determined about breast self-exams? (problems with breast self-exams)

answer

-breast self exams did not decrease suffering and death and, in fact, often lead to unnecessary worry, unnecessary tests, and increased health care costs -as a result of this research, several groups have downgraded the recommendation about breast self-exams form "do them and do them regularly" to "learn how to do them, and if your desire, do them to know your body and be able to recognize changes"

question

2 steps of breast awareness and self-exam (regular breast self-examination (BSE))

answer

1. face a mirror and check for changes in symmetry 2. either standing or lying down, use the pads of the three middle fingers to check for lumps. Follow an up and down pattern on the breast to ensure all tissue gets inspected

question

To do breast self-exam, how to do it?(long explanation) how breast cancer feels? when see doctor?

answer

-begin by standing in front of a mirror to inspect the breasts, looking for their usual symmetry. Some breasts are not symmetrical, and if this is not a change, it is okay -Raise and lower both arms while checking that the breast move evenly and freely -Next, inspect the skin, looking for areas of redness, thickening, or dimpling which might have the appearance of an orange peel. Look for any scaling on the nipple -To feel for lumps, raise one arm above your head while either standing or lying. This will flatten out the beast, making it easier to feel the tissue. Using the index, middle, and fourth fingers of your opposite hand, gently push down on the beast tissue and move the fingers in small circular motions, varying pressure from light to more firm. start at one edge of the breast and move upward and then downward, working your way across the breast until all of the breast tissue has been covered -Often breast tissue will feel dense and irregular, and this is usually normal -*Cancers usually feel like a dense or firm little rock and are very different from the normal breast tissue* -next, lower the arm and reach into the top of the underarm and pull downward with gentle pressure feeling for any enlarged lymph nodes. -To complete the exam, squeeze the tissue around the nipple. If you notice discharge from the nipple and you have not recently been breastfeeding, consult your doctor. Likewise, if you notice any asymmetry, skin changes, scaling on the nipple, or new lumps in the breast, you should see your doctor for evaluation

question

how helpful is to do regular breast self-exams?

answer

-It helps to do regular self-exams to become familiar with what your breast tissue feels like; then, if there is a change, you will notice

question

symptoms of breast cancer

answer

if breast cancer grows large enough, it can produce the following symptoms: -a lump in the breast or surrounding lymph nodes -thickening -dimpling -skin irritation -distortion -retraction or scaliness of the nipple -nipple discharge -tenderness

question

why should I care about breast cancer?

answer

-breast cancer accounts for 1 in every 3 cancer diagnosis in women in the US

question

treatments for breast cancer

answer

-treatments range from a lumpectomy to radial mastectomy to various combinations of variation or chemotherapy

question

treatments for breast cancer (medicines)

answer

--among nonsurgical options, promising results have been noted among women using selective estrogen-receptor modulators (SERMs), such as tamoxifen and raloxifene, particularly among women whose cancers appear to grow in response to estrogen. -these drugs, as well as new aromatase inhibitors, work by blocking estrogen

question

The 5-year survival rate for people with localized breast cancer

answer

The 5-year survival rate for people with localized breast cancer (which includes all people living 5 years after diagnosis, whether they are in remission, disease free, or under treatment) has rise from 80% in the 1950s to 98% today -however, these statistics vary dramatically, based on the stage of the cancer when it is first detected and whether it has spread

question

5-year survival rate for people with breast cancer that spread to lymph nodes or other organs

answer

-if the cancer has spread to the lymph nodes or other organs, the 5-year survival rate drops as low as 27%

question

how breast cancer incidence is with age?

answer

the incidence of breast cancer increases with age

question

risk factors for breast cancer

answer

-family history of breast cancer -menstrual periods that started early and ended late in life -obesity after menopause -recent use of oral contraceptives or postmenopausal hormone therapy -never bearing children or bearing a first child after age 30 -consuming two or more drinks of alcohol per day -physical inactivity -havign BRCA1 and BRCA2 genes

question

BRCA1 and BRCA2 gene mutations appears to account for approx _% of all cases of breast cancer , and women who possess these genes have a_% risk of developing breast cancer by age _as compared to a_risk in women without the mutations. these genes are_(how common, when use routine screening for them)

answer

-5 to 10% -60 to 80% -by age 70 -7% -are rare, routine screening for them is not recommended unless there is a strong family history of breast cancer

question

international differences in breast cancer incidence correlate with _

answer

-variations in diet, especially fat intake, although a causal role for these dietary factors has been not firmly established

question

relation between breast cancer risk and weight gain?

answer

-sudden weight gains has also been implicated with breast cancer

question

ways to reduce risk of breast cancer

answer

-regular exercise can reduce risk -study of dietary fiber indicate strong inverse relationship between dietary fiber and breast cancer. If you eat more fiber, breast cancer rates seem to go down, and if you eat less, rates seem to increase --You can take action to reduce risk by keeping your weight within a healthy range, drinking less than one alcoholic drink a day, and exercising regularly -starting now is your best means of prevention

question

question

how fast colorectal cancer spreads? why this is good? 5-year survival rate? problem with this?

answer

-because colorectal cancer tends to spread slowly, the prognosis is quite good if caught in early stages; in fact, when caught at an early, localized stage, 5-year survival rates are over 90% -However, the bad news is that in its early stages, colorectal cancer typically has no symptoms and only 39% of cases are caught in the earliest stage -those without insurance, or who avoid testing even with insurance, often are diagnosed at later stages when 5-year survival rates are much less

question

symptoms of colorectal cancer

answer

-as the disease progresses, bleeding from the rectum, blood in the stool, and changes in bowel habits are the major warning signals

question

only 10% of all Americans over age 50 have had the most basic screening test,_, in the past year, and slightly over 50% have had an _. (diagnosis methods of colorectal cancer). Although these rates are low, it should be noted that rates are even lower among_

answer

-men age 40 to 59 have a 1 in 158 chance of developing it, with a 1 in 36 lifetime risk -women age 40 to 59 have a 1 in 180 chance of developing it, with a 1 in 55 lifetime risk

question

is there any safe way to get a tan? probable problems of tanning. best sunscreen strength

answer

-unfortunately, no -there is no such thing as a "safe" tan, because a tan is visible evidence of UV-induced skin damage -the injury accumulated through years of tanning contributes to premature aging and increases your risk for disfiguring skin cancer, eye problems, and possible death from melanoma -According to the American cancer society, tanned skin provides only the equivalent of sun protection factor (SPF) 4 sunscreen--much too weak to be protective -It is not possible or practical to avoid sunlight completely, but wearing sunscreen of SPF 5 or higher every day can prevent further damage and diminish the cumulative effects of sun exposure

question

locations in body where basal and squamous cell carcinomas appear. how look? symptoms of basal and squamous carcinomas

answer

-basal and squamous cell carcinomas show up most commonly on the face, ears, neck, arms, hands, and legs as warty bumps, colored spots, or scaly patches -bleeding, itching, pain, or oozing are other symptoms that warrant attention

question

treatment for basal and squamous carcinoma

answer

-surgery may be necessary to remove them, but they are seldom life threatening

question

symptoms of melanoma

answer

-an invasive killer that may appear as a skin lesion -the lesion's size, shape, or color changes,and it spreads to regional organs and throughout the body

question

malignant melanomas account for _% of all skin cancer deaths

answer

75%

question

survival of melanoma

answer

-like other cancers, survival is largely dependent on how advanced the cancer is when diagnosed -if melanoma has not yet penetrated the underlying layers of skin, chances of survival are over 90% -however, if it is diagnosed after deeper layers of skin are penetrated and it has spread to other organs, the survival rate falls to 15%

question

ABCD rule for warning sings (symptoms) of melanoma

answer

-Assymetry: 1/2 of the mole or lesion does not match the other half -border irregularity: the edges are uneven, notched, or scalloped -color (color variation): pigmentation is not uniform. melanomas may vary in color from tan to deeper brown, reddish black, black, or deep bluish black -diameter: diameter is greater than 6 millimeters (about the size of a pea)

question

risk of skin cancer

answer

-anyone who overexposes himself or herself to ultraviolet (UV) radiation without adequate protection is at risk for skin cancer

question

the risk of skin cancer is greatest for people who:

answer

-have fair skin; blonde, red, or light brown hair; blue, green, or gray eyes -always burn before tanning or burn easily and peel readily -don't tan easily bit spend lots of time outdoors -use no or low-sun protection (SPF) sunscreens or expired sustain lotions -have had skin cancer or family history of skin cancer -experienced severe sunburns during childhood. contrary to popular thinking, there is no such thing as getting a base tan that protects against damage. The greater the exposure dose and the longer the time periods of exposure, the greater the risk

question

prevent skin cancer

answer

-preventing skin cancer is a matter of limiting exposure to harmful UV rays, whether in natural sunlight or tanning beds

question

what happens when you expose yourself to sunlight?

answer

-the skin responds to photodamage by increasing its thickness and the number of pigment cells (melanocytes), which produce the "tan" look -a tan is actually the body's way of trying to protect itself or defend against damage begins to accrue

question

why UV light causes cancer?

answer

-ultraviolet light (UV light) damages the skin's immune cells, lowering the normal immune protection of the skin and priming it for cancer

question

besides cancer, what photodamage causes? why?

answer

-photodamage also causes wrinkling by impairing the elastic substances (collagens) that keep skin soft and pliable

question

tips on staying safer in the sun; protecting your skin in the sun

answer

-seek shade from 10 am to 4 pm, when the sun's rays are strongest. Even on a cloudy day, up to 80% of the sun's rays can get through -Apply a sunscreen with SPF 15 or higher evenly to all uncovered skin before going outside. Look for a "broad-spectrum" sunscreen that protects against both UVA and UVB radiation. If the sunscreen label does not specify otherwise, assume you need to apply it 15 minutes before going outside -check the expiration date on your sunscreen. Sunscreens lose effectiveness over time. Often those sunscreen sales are on dated products. Beware! It is not a bargain if it does not work -Put sunscreen on your lips, nose, ears, neck, hands, and feet. If you do not have much hair, apply sunscreen to the top of your head too -Reapply sunscreen at least every 2 hours. The label will tell you how often you need to do this. If it is not waterproof, reapply after swimming or if you are sweating -water loose-fitting, light-colored clothing. You can now purchase clothing that has SPF protection in most sporting goods stores. A wide-brimmed hat will protect your head and face -use sunglasses with 99 to 100% UV protection to protect your eyes. Look for polarized lenses -Check your skin for cancer, keeping an eye out for changes in birthmarks, moles, or sunspots

question

In spite of the risks, many Americans are still "working on a tan," either outdoors or in tanning salons. There is increasing interest in determining why so many people continue tanning despite overwhelming evidence of potential harm. list reasons

answer

-some have suggested that tanning may have addictive qualities that actually keep people coming back even when they know better -Perhaps there is a link between high levels of UV light and increases in "feel good" endorphins -this little tanning high may make it harder for tanners to stop.

question

For risk of tanning salons

question

what prostate-specific antigen (PSA) test is about?

answer

-a blood test that screens for an indicator of prostate cancer

question

what US Preventive Services Task Force recommends regarding prostate-specific antigen (PSA) test ?

answer

Much as they did for breast self-exam recommendations in 2011, the US Preventive Services Task Force recommended that otherwise asymptomatic men no longer receive the routine PSA test because, overall, it does not save lives and may in fact lead to painful, unnecessary cancer treatments -if you have family history or other symptoms, consult with your physician

question

what is the good thing regarding prostate cancers?

answer

-fortunately, prostate cancers tend to progress slowly, and most prostate cancers are detected while they are still in the local or regional stages

question

risk factors of ovarian cancer

answer

-primary relatives (mother, daughter, sister) of a women who has had ovarian cancer are at increased risk. -A family or personal history of breast and colon cancer is also associated with increased risk -women who have never been pregnant are more likely to develop ovarian cancer than those who have given birth, and the more children a women has had, the less risk she faces -The use of estrogen alone as postmenopausal therapy may increase a women's risk, as well as smoking and obesity

answer

-with a 96% 5-year survival rate, it is one of the most curable forms of cancer

question

risk factors of testicular cancer (cause)

answer

-although the cause of testicular cancer is unknown, several risk factors have been identified -men with undescended testicles appear to be at greater risk, and some studies indicate a genetic influence

question

how testicualr cancer starts? how diagnose it? (diagnosis of testicular cancer)

answer

-testicular tumors first appear as an enlargement of the testis or thickening in testicular tissue -because this enlargement is often painless, the first indication young men have of a problem often comes from a testicular self-examination

question

how often testicular self-exams must be done and by who?

answer

-testicular self-exams have long been recommended for teen boys and young men to perform monthly as a means of detecting testicular cancer

question

what the US preventive services task force thinks about testicular self-examinations? however, what to do?

answer

however, recent studies have found that they are not cost-effective because the incidence of testicular cancer is low and most findings from self-exams result in testing what ultimately ends up being a noncancerous condition -For this reason, the US preventive services task force has dropped their recommendations for monthly testicular exams -regardless, most cases of testicular cancer are discovered through self-exam, and there is no other screening test for the disease

question

how to do the best testicular self-exam? how to do a testicular-self exam? when to consult a doctor?

answer

-the testicular self-exam is best done after a hot shower, which will relax the scrotum and make the exam easier -inspect the scrotum for any changes in color or in the size of each testicle. It is common for one testicle to be larger than the other, and if this is not a change, it is okay -hold a testicle using the three middle fingers of one hand. using small circular motions and light pressure, move the index and middle fingers of the second hand over the testicle until the whole surface has been covered -feel for changes in texture or small nodules that may feel like a pea or a grain of rice. Also note if there are areas where touch produces pain -along the back of each testicle is the epididymis, which contains the spermatic cord and the blood vessels serving the testicle. Feel this area with the index finger and the thumb, again looking for painful areas, changes in texture, or small lumps -repeat the process for the second testicle -if you notice any of the above, consult your doctor for further evaluation

question

how cancer spreads?

answer

Cancer spreads — or metastasizes — when cancer cells break away from the original tumor and travel through your bloodstream or lymphatic system to other parts of your body.

question

how melanoma begins?

answer

Melanoma begins in the melanocytes — cells that produce skin color, or pigment. Melanoma typically begins as a mole.

question

if catch melanoma early and has not spread, how remove it by surgery?

answer

If you catch the melanoma early and it hasn't spread, it can be surgically treated. Here you see a superficial melanoma being removed, along with the surrounding skin. The extra skin is taken to ensure that no cancer cells are left behind.

question

explain how melanoma metastasizes

answer

Melanoma is dangerous because it can spread beyond what you can see, moving deep into your skin where it can gain access to your lymphatic vessels. This allows cancer cells to travel to distant locations in your body. Cancer cells can also travel to different parts of your body by way of your blood vessels. In this example, melanoma cells migrate to a lymph node. From the lymph node, the melanoma cells can then travel to other parts of your body. Here, you see cancer spreading to the lung.
