In women, breast cancer is the most common cancer and the second most common cause of death from cancer. Approximately 180,000 patients--both women and men--are diagnosed with breast cancer each year, and 40,000 people die each year from it. Breast cancer is the leading cause of death in women aged 44-50 years. The overall 5-year survival rate is 60%, but if caught early, the rate increases to 80%.

Breast cancer is a malignant tumor that has developed from cells of the breast. The disease occurs primarily in women but occasionally occurs in men.

Many people do not realize that men have breast tissue and that they can develop breast cancer. Until puberty, young boys and girls have a small amount of breast tissue consisting of a few ducts (tubular passages) located under the nipple and areola (area around the nipple). At puberty, a girl's ovaries produce female hormones, causing breast ducts to grow, lobules (milk glands) to form at the ends of ducts, and the amount of stroma (fatty and connective tissue surrounding ducts and lobules) to increase. On the other hand, male hormones produced by the testicles prevent further growth of breast tissue. Men's breast tissue contains ducts, but only a few if any lobules.

Like all cells of the body, a man's breast duct cells can undergo cancerous changes. Because women have many more breast cells than men do and perhaps because their breast cells are constantly exposed to the growth-promoting effects of female hormones, breast cancer is much more common in women.

Many types of breast disorders can affect both men and women. Most breast disorders are benign (not cancerous). Benign breast tumors do not spread outside of the breast and are not life threatening. Other tumors are malignant (cancerous) and may become life threatening. Benign tumors, such as papillomas and fibroadenomas, are common in women but are extremely rare in men.

Lymphatic vessels are important structures in the breast. They are like veins, except that they carry lymph instead of blood. Lymph is a clear fluid that contains tissue fluid and waste products and immune system cells (cells that are important in fighting infections). Lymph nodes are small bean-shaped collections of immune system cells that are found along lymphatic vessels. Cancer cells can enter lymphatic vessels and spread to lymph nodes.

Most lymphatic vessels in the breast connect to lymph nodes under the arm (axillary lymph nodes). Some lymphatic vessels connect to lymph nodes inside the chest (internal mammary nodes) and either above or below the collarbone (supra- or infraclavicular nodes).

When breast cancer cells reach the axillary (underarm) lymph nodes, they may continue to grow, often causing the lymph nodes in that area to swell. If breast cancer cells have spread to the underarm lymph nodes, they are more likely to have spread to other organs of the body as well. This is why it is important to find out if breast cancer has spread to your axillary lymph nodes when you are choosing a treatment.

Yes, breast cancer can affect males as well as females, although I think that it's more rare amoung males.

in fact it affects males rarely but nuch more agressively coz there is no breast tissue to infiltrate, so the tumor attacks the chest directly
