Understanding Breast Cancer   

Breast cancer is a condition when cancer cells form in the breast tissue. Cancer can form in the milk-producing glands (lobules), or in the ducts that carry the milk from the gland to the nipple. Cancer can also form in fat tissue or connective tissue in the breast.

Breast cancer is formed when cells in the breast grow abnormally and uncontrollably. These cells generally form tumors that feel like a lump. Although usually occurs in women, breast cancer can also attack men.

Breast cancer is the most common, divided into several types.

• Ductal carcinoma in situ . This cancer grows in the ducts, and does not spread to the surrounding tissues. This type of cancer includes early and easily treated cancer. However, this cancer can spread to surrounding tissues if not treated immediately.
• Lobular carcinoma in situ . Is a cancer that grows in the lobules. Just like ductal carcinoma in situ , this cancer does not spread to surrounding tissues.
• Invasive ductal carcinoma . This cancer grows in the ducts and can spread to surrounding tissues, can even spread to other areas of the body. This type of cancer occurs in 70-80% of cases of breast cancer.
• Invasive lobular carcinoma . Is a cancer that grows in the lobules and can spread to surrounding tissues. This cancer occurs in 10% of cases of breast cancer.

While the type of breast cancer is rare

• Angiosarcoma. Is a type of cancer that grows in blood vessels and lymph channels in the breast.
• Paget's disease. Paget's disease is a cancer that grows in the nipple of the breast, then extends to the black area around the nipple (areola).
• Phyllodes tumor . This rare type of cancer grows in the connective tissue called the stroma.
• Inflammatory breast cancer . It is a rare type of breast cancer, but it develops rapidly and clogs the lymph channels, which makes the breasts look inflamed like infections.
• Triple negative breast cancer . Is a type of cancer that shows negative results on examination of the presence of estrogen hormone receptor (ER), progesterone (PR) receptor, and HER-2 protein receptor in cancer tissue, which is usually positive in breast cancer.
