Breast cancer risk is higher among women whose close blood relatives have this disease. The relatives can be from either the mother’s or father’s side of the family. Woman with cancer in one breast has a greater chance of getting a new cancer in the other breast or in another part of the same breast.
Breast cancer is a malignant (cancerous) growth that begins in the tissues of the breast. Over the course of a lifetime, one in eight women will be diagnosed with breast cancer. Breast cancer is a cancer of the breast tissue, which can occur in both women and men. Breast cancer may be one of the oldest known forms of cancer tumors in humans. Breast cancer is the fifth most common cause of cancer death (after lung cancer, stomach cancer, liver cancer, and colon cancer). Breast cancer kills more women in the United States than any cancer except lung cancer. Today, breast cancer, like other forms of cancer, is considered to be a result of damage to DNA. How this mechanism may occur comes from several known or hypothesized factors (such as exposure to ionizing radiation, or viral mutagenesis). Some factors lead to an increased rate of mutation (exposure to estrogens) and decreased repair (the BRCA1, BRCA2 and p53) genes. Alcohol generally appears to increase the risk of breast cancer.
Breast cancer can also occur in men, although it rarely does. Experts predict 178,000 women and 2,000 men will develop breast cancer in the United States. There are several different types of breast cancer. First is Ductal carcinoma begins in the cells lining the ducts that bring milk to the nipple and accounts for more than 75% of breast cancers. Second is Lobular carcinoma begins in the milk-secreting glands of the breast but is otherwise fairly similar in its behavior to ductal carcinoma. Other varieties of breast cancer can arise from the skin, fat, connective tissues, and other cells present in the breast. Some women have what is known as HER2-positive breast cancer. HER2, short for human epidermal growth factor receptor-2, is a gene that helps control cell growth, division, and repair. When cells have too many copies of this gene, cell growth speeds up.
