Lung Cancer symptoms
Persistent Cough, Chest pain, recurring Bronchitis
Lung Cancer Treatment
Surgery, chemotherapy (although lung cancer is very resistant to it), LUNG CANCER IS VERY DIFFICULT TO TREAT

-1:8 American women will have it in life
-5 year survival rate is 79%

women over 50, “Disease of civiliation”- processed foods, chemicals in air, genes, high fat/ high calorie diet, sedentary lifestyle, alcohol use, early onset of menstruation, first child after 30, obesity
Estrogen is a…
carcinogen
Breast Cancer detection
self-exam, breast exam by physician every year, mammogram every year
Prostate Cancer Fact
3rd leading cause of cancer deaths
Prostate Cancer Risk Factors/ Detection
age, diet, lifestyle, genes, “aging” cancer// EARLY DETECTION IS KEY- PSA Blood Test

surgical removal of prostate/ radiation
Female Reproductive Tract
Uterus, Cervix or Ovaries
Cervical Cancer
sexually transmitted, 80% stems from infection by HPV (unprotected sex), PAP test

Testicular Cancer Risk Factors
undescended testicles, history of family testicular cancer and being white
Leukemia
-Abnormal production of immature WBCs; rapidly growing cells displace red blood cells
-Immature WBCs cannot fight off infections

a gene that protects a cell from mutating into cancer

saturated fats, meats, alcohol
Radiation
a cause and cure of cancer
Diagnosing Cancer
