CANCER STUDY SUGGESTS USE OF BLOOD TEST

A new study of the effectiveness of a blood test for detecting prostate cancer found it twice as effective as a physical exam at finding early malignancies.

More than 10,000 men participated in the study of a test measuring levels of prostate-specific antigen, or PSA, a protein that seeps out of the walnut-size prostate gland if a tumor is present or the gland is enlarged.

Elevated PSA levels are a possible indicator of prostate cancer, which will kill 35,000 American men this year, said researchers led by Dr. William J. Catalona of the Washington University School of Medicine.
