cancer
Prostate cancer is cancer of the prostate gland. The prostate is part of the male reproductive system. This gland is locates inside the body at the base of the penis, just below the bladder and in front of the rectum. It is composed of the glandular and fibrous tissue enclosed in a capsule of connective tissue. The prostate is in the shape of a donut and about the size of a walnut. It surrounds the first inch or so of the urethra, the tube that carries urine from the bladder. Normal functions of the prostate depend on the presence of the male hormone testosterone, which is produced by the testes. The prostate produces semen, the thick, whitish fluid that carries sperm. Cancer of the prostate has become the number one cancer in American men. In the United States, approximately 1 in every 11 men will develop prostate cancer during his lifetime. Prostate cancer becomes increasingly common with each decade of life. Over 80 percent of all cases are diagnosed in men over 65. The incidence of prostate cancer increased 47 percent from 1973 to 1987, about a 2.6 percent increase each year. It is estimated that 106,00 new cases of prostate cancer were diagnosed in the US during the 1990. Black men in the US have the highest incidence of
To improve the outcome of treatment for patient's with prostate cancer, the National Cancer Institute supports clinical trials at many hospitals through out the United States. Treatment is being studied on animals and have been improving. Cancer can't be cured but as humans have done throughout history they will find a way to overcome tragedy. Chemotherapy is the last type of treating cancer. It is when the doctors use anti-cancer drugs. This method is usually used when the cancer is very severe and has spread to other parts of the body. The survival rate of prostate cancer patient's has increased since the 1950's. Some factors of these events can be explained by a combination of factors. There have been more frequent diagnosis of early cancers, the cancer is being diagnosed at earlier stages, and the treatment has improved. Scientists have suspected that hormones contribute to the development of prostate cancer. Men who's testicles were removed before puberty have little risk of developing this disease, apparently because the primary source of male hormones was removed. Currently, scientists are comparing testosterone production and metabolism in prostate cancer patients and their brothers as well as in men from families who do not have prostate cancer. Many studies have also been done with cancer causing agents. The results have not been very conclusive. En
