According to the American Cancer Society's statistics, breast cancer ranks second (after skin cancer) in the most common types of malignancy among Americans. It affects more than 250 000 women annually.

Each of your breasts consists of 12 to 20 lobes, which are made up of milk glands, milk ducts, adipose tissue (fat), lymph nodes, blood vessels and nerves. Sometimes abnormal cells can appear in any part of the breast. They usually tend to grow and multiply out of control, causing breast tumor formation.

If these cells have ability to invade into adjoining tissues or metastasize to other body areas, it is called breast cancer (or malignancy). In the majority of cases, this trouble occurs initially in milk ducts or glands. Scientists say that development of the breast malignancy is associated with hereditary gene mutations. That's why breast cancer sufferers often have family history of the same trouble.
