{draw:frame} Com 220 Professor Jon Saul By There are many risk factors involved with breast cancer. Many of these risk factors onecannot change. Gender is one of those risk factors. Breast cancer is found mainly in women who carrya one out of eight chance in being diagnosed during a lifetime. The main reason women develop breast cancer is because the “breast cells are constantly exposed to the growth-promoting effects of female hormonesestrogen and progesterone.” (ACS) Breast cancer is about 100 times more common in women than in men. Aging is another risk factor, which increases as one getsolder. Invasive breast cancer increases after age 45 from one out of eight to two out of three. Genetic risk factors are hereditary. If a woman has a family history of breast cancer, her risk factors of breast cancer are double. Race plays a role in the risk factors of breast cancer because white women have a slightly higher chance of forming breast cancer. African American women are more likely to die from breast cancer because they have more aggressive tumors. Women’s menstruation cycle has a risk factor involved with breast cancer. Women who started their menstruation cycle prior to age 12 will have an increased risk of getting breast cancer. "Women who weighed 8.8 pounds or more at birth have a 12% increase in breast cancer risk compared to women who weighed 6.6 to 7.69 pounds," says Isabel dos Santos Silva, MD, PhD, professor of epidemiology at the London School of Hygiene and Tropical Medicine, the study's lead author.

According to Mokbel and Cutuli (2006), during a study of untreated breast cancer, when breast cancer goes untreated, about 39% will develop invasivebreast cancer over about three decades. Out of those 39% about 45% will die from metastatic disease. Depending...
