Type Of Breast Cancer
Breast cancer is a malignant (cancerous) tumor that begins in the tissues of the breast. In the course of a lifetime, one in eight women will be diagnosed with cancer breast. Breast cancer is a cancer of the breast tissue, which can occur in both men and women. Breast cancer can be one of the oldest forms of tumors humans.Worldwide cancer, 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 other cancer except lung cancer. Today, Breast cancer, like other forms of cancer, is regarded as a result of DNA damage. As this mechanism may occur comes from several factors known or hypothesized (such as exposure to ionizing radiation mutagenesis, or viral). Some factors leading to a higher rate of mutation (exposure to estrogens) and decreased repair (BRCA1, BRCA2, and p53) genes. Alcohol generally appears to increase the risk of breast cancer.
Breast cancer can also occur in men, but rarely does. Experts predict that 178,000 women and 2,000 men will develop breast cancer in the United States. There are several types of cancer breast. First is ductal carcinoma begins in the cells lining the ducts that carry milk to the nipple and accounts for more than 75% of breast cancers. Second place is the lobular carcinoma starts in the milk-secreting glands of the breast, but otherwise quite similar in its behavior to ductal carcinoma. Other varieties of cancer breast may arise from the skin, fat, connective tissue and other cells in the breast. Some women have what is known as HER2-positive breast cancer. HER2 short for human consumption epidermal growth factor-2 is a gene that helps control cell growth, division and repair. When cells have too many copies of this gene, cell growth accelerates.
Causes of breast cancer
Simply being a woman is the main risk for breast cancer. While that men can also contract the disease is nearly 100 times more common in women than in men. The probability of breast cancer increases as women higher. Nearly 8 in 10 breast cancers found in women 50 years or more. About 5% to 10% of breast cancers are related to changes (mutations) in certain genes. The most common gene changes are those of the BRCA1 and BRCA2. The risk of breast cancer is higher among women whose close blood relatives have this disease. Relatives may be of either the mother or father's side of the family. Women with cancer in one breast has a greater chance of getting a new cancer in the other breast or elsewhere in the same breast. This is different from the first cancer coming back Many experts believe the main reason for this is growing tumors, because they are faster. Asian Indian women, Hispanics and Americans have a lower risk of breast cancer. Security types of abnormal biopsy may be linked to a slightly higher risk of breast cancer.Women who have received radiation treatment to the chest area (as treatment for another cancer) early in life have a much higher risk of breast cancer
Some pregnant women receiving the drug DES (diethylstilbestrol) because it was thought to reduce the chance of losing the baby. Recent studies have shown that these women (and their daughters who were exposed to DES in utero) have a slightly increased risk of breast cancer. Alcohol consumption is clearly linked to a slightly increased risk of breast cancer. Women who have 1 drink a day were very small risk. Those who have 2 to 5 drinks daily have about 1 ½ times the risk of women who do not drink alcohol. The American Cancer Society suggests limiting the amount you drink.Being overweight is associated with an increased risk of breast cancer, especially for women after change of life and if weight gain was occur during adulthood. Moreover, the risk appears to be greater if the extra fat is in the waist area. Breastfeeding and pregnancy: Some studies have shown that breast-feeding slightly lowers breast cancer risk, especially if breastfeeding lasts 1 ½ to 2 years. This could be because breast-feeding reduces the a woman's total number of menstrual periods, as does pregnancy. Women who began having periods early (before age 12) or were by the change of life (menopause) after the age of 55 are at slightly increased risk of breast cancer.
