Breast cancer is the growth of the malignant (cancer) that starts in the breast tissue. One in eight Women diagnosed with breast cancer. Breast cancer is cancer of the breast tissue, which can happen to women or men. Breast cancer has become one of the oldest forms is known as the cancer tumors in humans. In worldwide, breast cancer is the fifth most common cause of death (after lung cancer, stomach cancer, liver and colon cancer).

Breast cancer kills more women in the United States than any cancer except lung cancer. Breast cancer is considered to be a result of damage to DNA. The mechanism may occur from a number of factors (such as exposure to ionizing radiation, or a virus mutagenesis). Several factors led to an increase in the rate of mutation (exposure to estrogens) and decreases repair genes (BRCA1, BRCA2 and p53), and alcohol are generally appear to increase Risk of breast cancer.

Breast cancer can also occur in men, although it rarely happens. Experts estimate the 178,000 women and 2,000 men affected by breast cancer in the United States. There are some types of breast cancer. Ductal carcinoma starts first is in the cells lining the channels that carry milk to the nipple and accounted for more than 75% of breast cancer. Lobular carcinoma starts second on the issue of breast milk glands but is otherwise very similar to the behavior of ductal carcinoma. Other types of breast cancer can arise from the skin, fat, connective tissue, and other cells that are present on the breast.

Some women have what is known as HER2 positive breast cancer. HER2, abbreviation of human epidermal growth factor receptor-2, is a gene that helps control cell growth, Division, and repair. When cells have too many copies of these genes, cell growth is accelerating.

Being a woman is a major risk for breast cancer. While men can also get breast cancer, about 100 times lower than in women. Breast cancer risk rises if the age increased. Almost 8 out of 10 Breast Cancer found in women aged 50 or more. About 5% to 10% of breast cancer is related changes (mutations) in genes. The most common changes in genes are BRCA1 and BRCA2 breast cancer gene. Higher risks in women who have a family that had either relatives of breast cancerthat is derived from family side from the mother or father.

Women with breast cancer have a greater risk to get a new breast cancer in the other breast. This is different from the first cancer; many experts believe that the main reason is because they have a tendency more quickly in the development of tumors. Asian women, Hispanics and American Indians have a lower risk for breast cancer. Women have to do a treatment of radiation in the area of the breast (as a treatment for cancer of the other) early in order to prevent an Increased Risk of breast cancer

Some pregnant women were given the drug DES (diethylstilbestrol) is expected to lose their chances of losing a baby. Recent studies have shown that women (and their female children are exposed to DES in uterus), has a slightly increased risk for breast cancer. The use of alcohol is clearly associated with a bit of an increased risk for breast cancer. The use of alcohol is clearly associated with a bit of an increased risk for breast cancer. Women who drank 1 time a day had an increased risk is very small. But those who takes 2 to 5 times daily has about 1½ times the risk of women who do not drink alcohol

The American Cancer Society recommends limiting the number of the drink. It is associated with higher risk of breast cancer, especially for women after pregnancy and weight gain are increasing. Also, the risk appears to be higher if the extra fat at the waist.

Some studies have shown that breastfeeding is slightly lowered the risk of breast cancer, especially if breastfeeding lasts 1½ to 2 years. Women who started having menstrual periods (before age 12) or menopause after age 55 have a slightly increased risk of breast cancer.
