A new blood test holds promise of predicting possible cases of prostate cancer up to 10 years before the disease can be diagnosed, a six-year jump on current methods, scientists reported. The new test involves a different way of monitoring the enzyme PSA, or prostate specific antigen, in a man's blood, according to researchers at the National Institute on Aging and the Johns Hopkins University School of Medicine.

A little-known form of "bad" cholesterol that doctors cannot yet measure reliably may cause early heart disease just as often as its better-known cousins, a study suggests. The lesser-known culprit, called lipoprotein(a), may lurk in dangerously high levels in the blood of people whose other cholesterol levels appear normal on routine tests, researchers say.

New studies from Rhode Island and Germany found that shorter men face a greater risk of heart trouble and high blood pressure. The study of 6,589 Rhode Islanders looked at how other men compared with those who stood between 5 feet 7 inches and 5 feet 8 inches. Those under 5 feet 5 inches had a risk of heart disease that was double that of the moderate-size men, while men over 5 feet 10 inches had a risk that was 60% lower.

Defying what some believed to be insurmountable odds, researchers have narrowed the search for a prostate cancer gene to one small corner of the human genetic blueprint, a finding that promises improved diagnosis, new treatments and better survival rates for this most common of male cancers. An estimated 317,000 American men are diagnosed with prostate cancer each year and 40,000 die from it.

A pill that restores full function to impotent men is now in the final phases of clinical testing and could be offered for sale in the United States late next year, a British scientist says. The drug sildenfil blocks the action of an enzyme in the penis that tends to aggravate impotence, said Dr. Ian Osterloh, a researcher for Pfizer Inc. in Britain. "The pill is taken an hour or so before it is needed," said Osterloh. "It will do nothing, however, in the absence of sexual stimulation."

Millions of men who suffer enlarged prostates now can choose a one-hour treatment over drugs or surgery: a machine that microwaves the prostate to relieve urinary symptoms. The Food and Drug Administration approved the Prostatron, which kills excess prostate tissue by heating the gland with microwaves, based on studies showing it may help 75% of patients. It is an outpatient procedure that appears to work better than drugs and clearly is safer than surgery, said Dr.

A new study of hundreds of men with prostate cancer supports the idea that those over age 65 with slow-growing tumors may live as long without treatment as with it. It is the first such study solely among American men, and its findings parallel previous U.S. and international data, researchers said in today's issue of the Journal of the American Medical Assn. Prostate cancer is the second leading cancer killer of men, after lung cancer.

A study of black men has shown for the first time that exercise can significantly reduce severe high blood pressure. What doctors call hypertension afflicts 50 million Americans and is especially common among blacks. While exercise is routinely recommended for people with mildly high blood pressure, it has not been studied for those with more serious cases. "Our results show that the effectiveness of moderately intense exercise extends to patients with severe hypertension," wrote Dr. Peter F.

Prostate cancer, which hits twice as many black men as white men, is often diagnosed at a later stage in blacks, a University of Wisconsin study said. The survey, reported at a medical convention in Chicago, said that of 801 men diagnosed and treated for prostate cancer, the disease had spread beyond the prostate to other areas of the pelvis in 56% of the black patients, as opposed to 38% of the whites. Prostate cancer is the most common cancer among men.

Older men with early prostate cancers may benefit as much from "watchful waiting" as from aggressive treatments like radical surgery, which rose in frequency almost sixfold from 1984 to 1990, researchers say in today's Journal of the American Medical Assn. "We have, in essence, an epidemic of treatment and no scientific proof that it's valid," said Dr. John Wasson, who worked on the two studies in the journal. In one of the studies, led by Dr.
