Breast Cancer

Breast Cancer

Breast cancer is a cancer of the glandular breast tissue.

Worldwide, breast cancer is the fifth most common cause of cancer death (after lung cancer, stomach cancer, liver cancer, and colon cancer). In 2005, breast cancer caused 502,000 deaths (7% of cancer deaths; almost 1% of all deaths) worldwide. Among women worldwide, breast cancer is the most common cancer and the most common cause of cancer death.[1]

In the United States, breast cancer is the third most common cause of cancer death (after lung cancer and colon cancer). In 2007, breast cancer is expected to cause 40,910 deaths (7% of cancer deaths; almost 2% of all deaths) in the U.S.[2] Among women in the U.S., breast cancer is the most common cancer and the second most common cause of cancer death (after lung cancer). Women in the U.S. have a 1 in 8 lifetime chance of developing invasive breast cancer and a 1 in 33 chance of breast cancer causing their death.[3]

The number of cases has significantly increased since the 1970s, a phenomenon partly blamed on modern lifestyles in the Western world.[4][5]

Excised breast tissue showing a stellate, pale area of cancer measuring 2cm across. The tumor could be felt as a hard, mobile lump before the surgical excision.Because the breast is composed of identical tissues in males and females, breast cancer also occurs in males, though it is less common.[6]

Time line of breast cancer suggesting probable heterogeneity. Primary breast cancers begin as single (or more) cells which have lost normal regulation of differentiation and proliferation but remain confined within the basement membrane of the duct or lobule. As these cells go through several doublings, at some point they invade through the basement membrane of the duct or lobule and ultimately metastasize to distant organs.[7]
