In the United States in 1995 alone, 43, 063 died from breast cancer. 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. 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 bodys 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 leader 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 todays 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 womens 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 today one needs a maximum of only 20 % of overall calories from fat sources. Epidemiology experiments are hard to perform on humans because it is extremely hard to control a humans whole life diet.

Therefore, it is much easier to compare cultures of peoples which tend to determine the food intake of those people. In Iceland, the diet tends to be derived from healthy foods of the ocean, including lowfat fish and vegetables. But when researchers increased the amount of fat in their diets, their rate of breast cancer shot up, demonstrating its potential in the Iceland people. A number of doctors simply take the common sense approach to preventing against breast cancer exercising and getting your proper nutrients is the best precaution. The New York Times reported in May of 1997 a study that was done on 25, 000 women in Norway. Compared with sedentary women, those who exercised at least four hours a week had a 37 % lower risk of developing breast cancer.

One leading hypothesis on how exercise fights cancer is brought by Dr. Leslie Bernstein, a professor of preventative medicine at the University of Southern California. Dr. Bernstein says that exercising reduces a womans exposure to estrogen, reducing that possible oncogene. Also, vitamins and minerals including A, C, and E help to fight cancer says F. de Ward, a cancer researcher.

He claims that the problem might not just lie in fat, but overall nutrition. Several medical procedures or side effects of them have been thought to promote breast cancer. It was hypothesized by staff at the NEJM that self done abortions could greatly increase the chances of getting cancer as during pregnancy the cells in the breast quickly divide and reproduce. By having an abortion and thus suddenly halting cell division, a number of cells would become greatly unprotected by their not being any differentiation, and thus would be vulnerable to cancer. Prevention is one point of the puzzle to cure breast cancer, but it is extremely important to get breast examinations often to make sure of no lumps or early tumors. The simplest forms of breast exam is a self exam, one with a doctor, or a mammography.

A mammogram is simply an X-ray of the breast. Mammography can pick up small legions of under one half a centimeter, whereas one can not feel a lump until it is a full centimeter in diameter. But, if breasts are small or dense, a mammogram might not pick it up. Another procedure could be a wire localization. A thin wire is used to show where the legion is after the wire is inserted, and local anesthetic is administered. Thermography is based on the idea that cancer gives off more heat than regular cells.

Transillumination is founded in the concept that light shines through breast tissue, but us blocked by lumps. An ultrasound is when high frequency sound waves are sent off in a radar fashion, and reflect off objects that they hit. A CAT scan is the process of visually cutting the body into cross-sections. But, another controversy runs deep in the issue of using CAT scans to find cancer tissue. The radiation required to examine a five milliliter lump is often considered simply too high for safety, and has a possibility of just simply spreading the cancer to other body parts. A MRI takes advantage of the electromagnetic qualities of the hydrogen nucleus to produce an electric chart or visual.

While the most common form of breast exam is mammography, there are many critics of that procedure. In a cancer study conducted by the American Cancer Society due to be released to the public in June, the organization does a twenty year follow up on an experiment started in the early 70 s. Based on a 96 % follow up from 1993 to 1995, 4051 women had breast cancer. Out of those cancer patients, 2658 were alive (66 %), and 1393 (34 %) were dead. At the end of the twenty year period, those who were forced into examination were 20 times less likely to get cancer. One startling conclusion enforces a hypothesis dating back to the days of Darwin.

Younger women are at increased risk for biologically more aggressive carcinoma, meaning that the future battle for curing cancer is not getting any easier. +which cancer growths are dependant upon the growth of blood vessels to nurture the cancer cells. New drugs are being developed to stop the growth of cancer cells by preventing nourishment of the cancers by new blood vessels. By cutting off the blood supply to the cells, they die, and thus are eliminated from the system. There are various treatments aimed at killing the cancerous cells from surgically removing that area of the body to killing it off by use of chemicals.

A very common operation is chemotherapy. Chemotherapy is a drug designed to kill rapidly dividing cells. Monoclonal antibodies are antibodies that can be engineered to carry drugs or radiation directly to the tumor, and is an efficient way of delivering chemotherapy to the body... One solution to cancer may be hormone therapy.

The hormone, usually tamoxifen, slows growth of cancer cells by blocking some growth enhancing properties of estrogen. Tamoxifen is the most commonly used breast cancer drug in the world. It works, works well, and does it with relatively few side effects, said Dr. Wicker man of a Dallas clinic. The controversy over Tamoxifen is that it might cause other types of cancer. In 1981, the National Cancer Institute ran a test in which women took a placebo or Tamoxifen.

Women with the drug were less likely to develop cancer of the breast, but they were more likely to develop blood clots, ovarian cancer, or breast cancer. Chemotherapy involving tamoxifen has proved useful in delaying breast recurrence, but the majority of patients treated with Tamoxifen eventually go into relapse. There are several physical operations. Traditionally, there are three types of cancer treatments: radiation, mastectomy, cytotoxic chemotherapy. The type of surgery really has its basis on the size of the tumor. A lumpectomy removes the tumor and surrounding tissues.

A simple mastectomy removes the breast, nearby lymph nodes, and portions of the chest and arms. Doctors can perform preventative mastectomies. Some surgeons feel that if the breast is fairly lumpy, and the patient appears to be in very high risk of breast cancer, the surgery may be beneficial. The whole surgery is highly controversial.

A total bilateral mastectomy and reconstruction is preferred. This removal takes out all of the breast including the nipple and duct system so that there can be little chance of relapse. One complication that can result in cancer is Ductal Carcinoma inside. This area houses the lobules and ducts and is the area in which milk is produced.

Similar to rust clogging up pipes, often extra cells or cancerous cells will clog up the tubes providing for some discomfort and other risks. Studies show that 20 - 25 % of women with untreated DCIS will get invasive cancer within 10 years. Also dealing with the lactating in women is breast cancer during pregnancy. Breast cancer during pregnancy is usually not harmful except for minor complications. Breast cancer during that period could also be hard to detect because of the rapidly expanding breasts, and other new growth. On a final note, men can also get breast cancer, but it is often more evident as there tends to be less flesh in a mans chest than in a females.

Until individuals commit themselves to a healthy diet, watch for signs of cancer, or even volunteer time, we will always have the problem. While there are many factors from weight to factors that one cant even control, taking a look at the whole picture and evaluating your opinions into your own choice, and considering other references will end in the best decision for yourself
