Most patients diagnosed with early-stage prostate cancer will live just as long if they simply watch their cancers rather than have them surgically removed, according to the results of a landmark clinical trial that could upend the medical approach to a disease that affects 1 in 6 men. The study, which focused on cancers still confined to the prostate, should reassure patients who want to avoid distressing side effects of surgery - such as urinary incontinence...

A growing body of evidence suggests that the widely used diabetes drug metformin can reduce the risk of cancer, researchers said Wednesday. A study in mice exposed to tobacco carcinogens shows that the drug can reduce the development of lung tumors by more than 70%, and results from a small clinical trial in Japan suggest it can reduce rates of colorectal tumors in humans. The National Cancer Institute is now organizing a clinical trial to test the drug in people who smoke, and other trials are testing it against breast and prostate cancer.

If people weren't afraid of CT scans before now, it might just be a matter of time until they are. Or perhaps until lawmakers take matters into their own hands. L.A. Times staff writer Alan Zarembo wrote Tuesday of local hospitals that said they were simply following the manufacturer's recommendations: " Two More Hospitals Report CT Scan Radiation Overdoses ." Judith Graham wrote recently in the Chicago Tribune about attempts to protect children from excess radiation: " Clamping Down on CT Scans for Kids ."

Test-tube experiments at a National Institutes of Health laboratory show evidence that a drug called hydroxyurea may block or slow the replication of the AIDS virus, researchers report. In a study published in the journal Science, researchers at the National Cancer Institute report that HIV, which causes AIDS, is unable to reproduce in cells exposed to hydroxyurea, a cancer drug that has been used for 30 years.

Guidelines for breast cancer screening could be changed by some medical organizations once they fully analyze new studies showing mammograms may provide little benefit for women before age 50, officials said. Dr. Gerald P. Murphy, chief medical officer at the American Cancer Society, said his group is examining the new studies, but "not all of the information has been evaluated, and there are no conclusions that can be made on this as yet."

A controversial drug to treat two lethal types of cancer has won approval from the Food and Drug Administration for wider trials in humans, it was announced. An FDA spokeswoman said the agency will permit the National Cancer Institute to expand the use of interleukin-2 to a larger number of patients with advanced melanoma and kidney cancer. The treatment will be available to patients selected for participation in tests at NCI-approved cancer centers.

Frying, broiling and barbecuing produce potentially carcinogenic compounds in meat, chicken and fish, but microwaving, stewing and poaching do not, the National Cancer Institute said in reporting on a laboratory study. Researchers at the institute's Division of Cancer Etiology found that cooking at high temperatures and for a long time produced compounds that caused cancer in monkeys and other lab animals. Dr.
