Breast Cancer (Carcinoma) Markers

 

 

 

Breast cancer is a cancer of the breast tissue. Worldwide, it is the most common form of cancer in females - affecting, at some time in their lives, approximately one out of thirty-nine to one out of three women who reach age ninety in the Western world. According to the United Nations World Health Organization, it is the leading cause of cancer deaths among women worldwide. The number of cases 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 far less common.
