Largest-Ever Study of Prostate Cancer Starts

From Times Wire Reports

Federal health officials launched the world's biggest prostate cancer study, which will examine whether the nutrients vitamin E and selenium ward off the disease.

The dietary supplements are antioxidants that are believed to help control cell damage that can lead to cancer.

The National Cancer Institute said the study--involving 32,400 healthy men from the U.S., Puerto Rico and Canada--will last 12 years.

Prostate cancer, the second-deadliest form of cancer for men after lung cancer, is expected to cause 31,500 deaths this year, the American Cancer Society predicts.
