"It is uncomfortable but not painful, and it's generally brief, lasting less than a minute," assures Prof Lim of Singapore.
A serious drawback to DRE is that it cannot be relied totally. As such, Letran suggested for a blood test that measures prostate-specific antigen (PSA), a protein given off by prostate tissue. In general, the higher the PSA, the greater the cancer risk. The Ministry of Health in Singapore believes that the combination of DRE and PSA enhances early detection.
But DRE and PSA tests are not enough. If the urologist finds something is wrong, he recommends a transrectal ultrasound, the same technology that produces images of babies in the womb. While ultrasound can't distinguish healthy cells from cancer cells, it can help direct a needle biopsy. Two features help a doctor determine the likely course of the cancer and the best treatment: how far the cancer has spread (if the cancer is confined to a small part of the prostate gland, generally many years will pass before it spreads to areas around the gland and then to bone and other parts of the body) and how malignant the cells look (prostate cancer cells that are more distorted under the microscope tend to grow and spread more quickly). Treatment may serious affect a man's lifestyle, according to Letran. Major surgery, radiation therapy, and drugs for prostate cancer often cause impotence and may cause incontinence. In addition, Letran urges that food rich in animal fat should be avoided. "Eat more vegetables, especially tomatoes," he suggests. "Vitamins like selenium and zinc are being studied for possible prevention of prostate cancer." The question that ponders many researchers is why Prostate Cancer is ranked third or less in under-developed countries. Some say it's because of more physical work men are subject to in their lifetime compared to developed countries.
