In other cases, there is no tumor formed in the breasts.

Ductal carcinoma in situ (DCIS) is also called intraductal carcinoma. It is noninvasive breast cancer. The major difference in these two diseases; DCIS and the noninvasive breast cancer is that the cells have not spread all over the walls of the ducts in to the tissues. Because of this, DCIS cannot metastasize outside the breast. DCIS is said to be pre-cancer reason being that it can go to be invasive cancer (Berg et al, 2006). DCIS affects the milk ducts and does not invade to other parts of the body while the IDC affects the milk ducts and invades other tissues.

The primary lung cancer is the cancer that has started in the lungs. It has not affected any other part in the body. It is classified in to two groups; small cell lung cancer and the non-small cell lung cancer. The metastatic lung cancer is one which has spread to other parts of the body like the colon, breasts, kidney and the prostate. It is a secondary cancer. It spreads via the lymphatic system or the bloodstream (Paez et al, 2004).
