The breasts are at the chest wall and developing in women during puberty, when the female hormones are starting to be produced (estrogen, progesterone) from the ovaries. In men, the breasts remain atrophic and rarely swelling (gynecomastia), so the man should be examined. The breast consists of 15-20 lobules, which contain many smaller lobules, which in turn contain glands that produce milk. The drainage is done by small tubes (pores) which flow into the nipple, located in the center of a dark area of skin called the areola.
Among smaller loules and resources there is fat. The breasts also contain lymph vessels and lymph nodes which trap bacteria, cancer cells and other harmful substances, preventing them to reach the circulation.
So breast are instruments used to produce milk and consisting of different tissues (glandular tissue, adipose tissue, muscle tissue), which in turn consist of several cells (glandular cells that produce milk, fat cells that support the breast, muscle cells which help in the secretion of milk).
Breast cancer is being developed from the glandular cells of resources and small lobules. Rarely, however, are developed malignancies and adipose or muscle tissue, called sarcomas. Any swelling of breast is not necessary cancer. Benign tumors are usually smooth, not extended to other organs and the removal involves the non-recurrence them. In contrast, breast cancer grows progressively, invades adjacent organs or tissues (skin, muscle, lymph nodes) and later can metastasize to distant organs (liver, lungs, bones, brain kg.). We emphasize that breast cancer is not contagious.
