Male Breast Cancer
Male Breast Cancer, Causes, Risk Factors and Prevention
By Istvan S Diego
Introduction
Notwithstanding that male breast cancer is a rare phenomenon, it is still possible. Such cases account for only 1% of all breast cancer. The American Cancer Society forecasts that over 1,000 new cases of breast cancer in men will be diagnosed in 2010 ("Male Breast Cancer"). The survival rate in men is lower than in women, mostly because men often report the symptoms of breast cancer too late ("Male Breast Cancer"). The disease is more likely to spread, leaving many men with less hope that treatment will lead to recovery. The main reasons of that are first of all the lack of the research in this field that leads to the second reason that is men’s unawareness about the possibility of male breast cancer. The unawareness leads to late discovery and high death rate.
Male Breast Cancer
According the American Cancer Society, like all cells of the body, men's breast duct cells can undergo cancerous changes. Breast cancer is less common in men, because their breast duct cells(lymph systems) located under the nipple and areola (area around the nipple) are less developed than those of women because their breast cells are not constantly exposed to the growth-promoting effects of female hormones ("Male Breast Cancer").
Breast cancer can spread through lymph system. Lymph nodes are small, bean-shaped collections of immune system cells connected by lymphatic vessels. Lymphatic vessels are like small veins. Lymph contains tissue fluid and waste products, as well as immune system cells. Breast cancer cells can enter lymphatic vessels and begin to grow in lymph nodes ("What Is Breast Cancer in men?").
Most lymphatic vessels in the breast connect to lymph nodes under the arm (axillary nodes). Some lymphatic vessels connect to lymph nodes near the breast bone (internal mammary nodes) and either above or below the collarbone (supraclavicular or infraclavicular nodes) ("What Is Breast
