Prostate Cancer
Rates of prostate cancer
vary widely across the world. It is least common in South and East Asia, more
common in Europe, though the rates vary widely between countries, and most
common in the United States. According to the American Cancer Society, prostate cancer is
least common among Asian men and most common among black men with figures for
European men in between.
However, these high rates may be
affected by increasing rates of detection. Although prostate cancer can
sometimes strike younger men, the risk of getting it increases with age and
more than seventy percent of men diagnosed with the disease are over the age of
sixty five.
Prostate cancer can occur in men only;
the prostate is exculsively of the male reproductive tract. Prostate cancer is a disease in which cancer
develops in the prostate of the male reproductive system, this happens when cells in the prostate begin to grow
out of control and can then invade nearby tissues or spread throughout the
body. Large collections of this out of control tissue are called tumors. The
tumor usually grows slowly and remains confined to the gland for many years.
During this time, the tumor produces little or no symptoms
or outward signs (abnormalities on physical examination). As the cancer
advances, however, it can spread beyond the prostate into the surrounding
tissues (local spread). Moreover, the cancer also can metastasize (spread even
farther) throughout other areas of the body, such as the bones, lungs, and
liver. Symptoms and signs, therefore, are more often associated with advanced
prostate cancer. Prostate cancer may cause pain, difficulty in urinating,
erectile dysfunction and other symptoms.
The cause of prostate cancer has not
been identified but the cancer is thought to be related to benign prostatic
hypertrophy (BHP). The risk factors of prostate cancer include advancing age,
heredity, hormonal influences, and such enviromental toxins, chemicals, and
industrial products. The best way to try and prevent prostate cancer
is to modify the risk factors for the disease that you have control over.
You may want to try to eat a low fat diet that is rich in
fruits and vegetables. Certain foods, vitamins and minerals have been suggested
to decrease your chances of getting prostate cancer, however doctors are still studying
more data before any particular food or supplement can be endorsed for
preventing the disease. Currently, there are studies looking at selenium,
lycopen, vitamin A and other retinoids, vitamin D, vitamin E, and soy for
prostate cancer prevention.
Since prostate cancer is a disease of
older men, many will die of other causes before the disease can spread or cause
symptoms. Deciding on treatment can be
daunting not only because there are far better options for treatment today that
they were ten years ago but also because not enough relaiable data are
available on which to base the decisions. Prostate cancer can be treated with surgery,
radiation therapy, hormone therapy,
occasionally chemotherapy, or some combination of these.
Most men who have the risk factors do
not get the disease, on the other hand men who do get the disease often have no
known risk factors, except for growing older.
If you think that you may be at risk, you should consult your doctor
immediately so that you may be given suggestions on ways of reducing your risk
and can plan scheduled check-ups.
