Breast Cancer Is Most Aggressive in African American Women
Breast cancer is the second leading cause of deaths in American women, with lung cancer being the first. It is the most common cancer in women not including non-melanoma skin cancers. Breast cancer is a group of related diseases in which cells in the breast, most commonly in the lining of the milk ducts or milk producing glands become abnormal and divide without control or order as a normal cell would. When cancer cells break away from the original tumor and enter the blood stream or the lymphatic system, secondary tumors may form, invading or damaging other parts of the body including vital organs. According to the World Health Organization about more than 1.2 million people are diagnosed with breast cancer a year worldwide. The WHO also states that there were 7.6 million deaths related to breast cancer in 2008, which was a huge 6.4 million rise from the deaths in 2001 that’s an estimated 625,000 new cases of invasive breast cancer, including stages 1-4 were diagnosed among women in the United States. Another 55,400 were diagnosed with Ductal Carcinoma in Situ, (DCIS) a noninvasive breast cancer. DCIS is the earliest form of breast cancer, confined to the milk ducts of the breast. Although much less common of course, breast cancer also occurs in men. It was estimated that there will be 40,600 deaths related to breast cancer, with 40,200 in women and only 400 deaths in men in the United States. The incidence rate of breast cancer (number of new breast cancers per 100,000 women) increased approximately 4% during the 80’s but leveled off to 100.6 cases per 100,000 women in the 90’s. The statistics rose 40% by the twenty-first century. These risk models were based on population averages. Each woman’s breast cancer risk may be higher or lower depending upon several factors such as family history, Genetics, age of menstruation and other factors that have not yet been identified.
