In the United States in 1995 alone, 43,063 died from Breast cancer Essay. It is the number two cancer killer and the number one cancer in females ages 15 to 54. On average if a woman gets this disease, their life expectancy drops nineteen and a half years. This cancer is within the top three cancers of all women above the age of 15, and comprises 6% of all health care costs in the U.S.
totaling an astounding 35 billion dollars a year. An average woman is said to have a one in thirty chance of getting the cancer, but if that person had family history of the disease, their chances have been measured up to a one in six chance. 69 percent of African American women survive from it, and there are predicted to be nearly two million new cases reported this year in the U.S. The disease is breast cancer.Order now
Breast cancer is a group of rapidly reproducing, undifferentiated cells in the area of the breast in women.
The earliest changes occur in the epithelial cells of the terminal end buds (TEB) of the breast milk ductal system. While the outlining steps of breast cancer are unknown, the cells
in the breast trigger a reaction of cell reproduction. These new cancer cells form tumors. If cancer cells are active or are considered malign, the tumor grows at tremendous speeds, and may end up in metastasis. Metastasis is a complex process in which cells break away from their primary tumors, and via the blood supply or through the lymph system relocate into other organs, thus spreading cancer throughout the body if left untreated. Generally, if a lump is smaller than one centimeter, it is considered benign, although every woman should consult her doctor about
any unusual bumps or feeling in the chest.
One sign of breast cancer results from ductal cancer in the breast. A once hollow open tube could be completely clogged up with cancerous cells thus leaving an awkward feeling in the chest area. Other complications that result from this cancer and others is on top of the clogging and cramming of the system, the body’s need to not only supply for itself, but for the large tumors.
Bone mass is a cumulative effect of estrogen on bones scientists say, and so the study focused on the more easily observed density and mass of bone tissue in women. Four levels were accounted for, and the research was tallied. The risk for getting cancer in the lowest stage of bone mass was about 2%, and then 2.
6, 2.7, and 7.0 in the second, third, and fourth levels of higher mass respectively. This research lended itself to the assumption that cumulative exposure to estrogen may play part in breast cancer. Other hormonal factors have been viewed as potential breast cancer causing agents. Birth control pills are thought by some to lead to breast cancer.
Early birth control pills used much more estrogen and progesterone than today’s pills, and therefore could cause cancer. Lots of contradictory results were found in research of the pill because women who have been taking it for ten or twenty years have actually been taking several different types of pills with different levels of cancer causing hormones. But, in general, the report concluded that the pill doubled to up to quadrupled the women’s chance of having breast cancer. Diethylstilbestrol (DES) was used to increase fertility in 1940 through 1960 and also decrease the chances of having a miscarriage. Studies show it to increase the rate of breast cancer by 1.4.
Exposure to estrogen during periods of rapid growth in the breast tissue during pregnancy may increase risk. In August of 1989, Swedish doctor Leif Bergkvist studied
23244 women ages 35 and up and found that an estrogen supplement that they were taking quadrupled chances for breast cancer.
Fats have been thought to increase the rate of breast cancer occurrence. Conversely, many studies have drawn out a link between fats and cancers. In the 1940’s, Albert Tannenbaum gave rats high fat diets and found that it increased their rates of breast cancer by 27%. The fat threshold for rats is reiterated by many in the health field .
