Silica dust, though classified a human carcinogen by the International Agency for Research on Cancer, is considered less dangerous than asbestos, so its management is not governed by strict regulations...
Much of the controversy stems from the test's effectiveness in early detection. But its greatest value lies in its ability to help men who already have prostate cancer--a value that was enhanced last week with the publication in the Journal of the American Medical Association of the first detailed study of the natural history of prostate cancer. Researchers from Johns Hopkins used data from the study to develop a formula that gives patients the most precise estimate yet of their chances of surviving a future recurrence...
...prostate is surgically removed (or destroyed by radiation therapy), the PSA level should fall to zero. So unlike the more ambiguous pre-operation tests, any increase in PSA levels after surgery almost always means that some tumor cells have escaped and are growing elsewhere in the body. Prostate cancer usually grows so slowly, however, that patients often die of something else before its spread becomes noticeable...
...drugs that target the still invisible metastasis but have significant side effects--effects that amount to a chemical castration. The men become impotent, lose muscle mass and develop osteoporosis. "Now we're seeing patients who have been on hormonal therapy for five, six, eight years with no sign of cancer in their body other than their PSA test," says Dr. Mario Eisenberger, one of the study's co-authors. Were they castrated for nothing...
FILL 'ER UP Loading up on liquids--any kind, including water, coffee or soda--may help protect the bladder from cancer. Data on 50,000 men show that consuming ten 8-oz. glasses each day can cut the risk of bladder cancer in half. The liquids probably flush away carcinogens and keep urine diluted so toxins make less contact with the bladder wall. Half a gallon a day may sound like a lot to swallow, but it's only about three glasses more than most people already drink...
