Breast
Cancer
If
and when cancer is noticed at glandular breast tissue, it is considered
as Breast cancer .
Breast cancer is the world's 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 worldwide. Among women worldwide,
breast cancer is the most common cause of cancer death
Statistics
across USA
Breast cancer is the third most common cause of cancer death In 2007,
with a death tally of 40,910 . 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). .. Nevertheless, a U.S. study
conducted in 2005 by the Society for Women's Health Research indicated
that breast cancer remains the most feared disease, even though heart
disease is a much more common cause of death among women
The number of cases worldwide has significantly increased since the
1970s, a phenomenon partly blamed on modern lifestyles in the Western
world. Because the breast is composed of identical tissues in males and
females, breast cancer also occurs in males, though it is less common
Breast
Cancer - Cause
Breast cancer gene called BRCA is one of
several genetic mutations (alterations in the body's genetic material) associated with the development of breast and ovarian
cancer.
There are
two types of breast cancers known as BRCA1
( breast cancer 1) and BRCA2 ( breast cancer 2), that can be inherited and lead to a markedly
increased risk for developing breast cancer and ovarian cancer. Ductal carcinoma starts in
the tubes (ducts) that move milk from the breast to the nipple. Most
breast cancers are of this type. Lobular carcinoma starts in parts of
the breast, called lobules, that produce milk. In rare cases, breast
cancer can start in other areas of the breast.
