Breast cancer is the most commonly diagnosed non-skin cancer and the American women. It is estimated that about 213,000 American women with breast cancer in 2006. Breast cancer risk in women with increasing age. For years, scientists have certain characteristics, risk factors that affect women identified, based generally on the possibility of contracting the disease. But many women with breast cancer are not a risk factor for older women is increasing known, and many of them are not risk factors for breast cancer.
Breast cancer incidence is significantly higher in the West, in Europe or North America, Third World countries. The Americans have the highest incidence of breast cancer in the world. Women in the United States breast cancer is the most common cancer and the second leading cause of cancer death (after lung cancer). Women in the United States, 1 8 (12 5%) probability of invasive breast cancer and 1-35 (3%) chance of breast cancer caused her death.
Breast cancer affects one in eight women during their lifetime. Breast cancer kills more women in the United States than all other cancers of the lung. No one knows why some women with breast cancer, but there are some risk factors.
Breast cancer causes
Genes in cells carry hereditary information, a person from their parents. hereditary breast cancer accounts for about 5% to 10% of all breast cancer cases. Some of the new genes with breast cancer are more common in certain ethnic groups.
Now scientists are trying to determine whether the compound genetic and environmental factors and the person may increase the risk of breast cancer. Breast cancer can be a time for many reasons.
Events of reproductive age - age of child-bearing age women stimulated to divide estrogen breast tissue cells. More estrogen a woman is to be, the greater the risk of breast cancer exposed. Exposure to estrogen increases if a woman began a period of more than 11 years experience menopause at the age of 55.
BRCA1 and BRCA2 addition, mutated genes that can help someone with breast cancer. Scientists have known for some of these genes, and we try to identify other
Treatment of breast cancer
Today, radical surgery is rarely the chest. However, most female candidates for lumpectomy or simple parallel. If you select a page, you can breast reconstruction.
Chemotherapy uses drugs to kill cancer cells. Size of the tumor characteristics of tumor cells and to what extent the spread of cancer to determine need for chemotherapy. If the tumor is a high probability of return or spread to other parts of the body, your doctor may recommend chemotherapy after surgery to reduce the likelihood of recurrence of the disease. This is called adjuvant chemotherapy. If the cancer has spread to other parts of the body, chemotherapy may be recommended to combat the cancer and reduce symptoms, the cancer is the cause.
a simple parallel: the chest, the surgeon removes all breast tissue - lobules, ducts, fatty tissue and skin, including the nipple and areola. According to results of operations and further research may need additional treatment to the chest wall radiotherapy, chemotherapy or hormone therapy.
Invasive cancer can be given if they spread to other tissues. Those who do not spread to other tissues are called non-invasive. Carcinoma in situ is a noninvasive cancer .
