Blood test may cut prostate death rates

A new study continues the ongoing debate over using the PSA blood test to screen for prostate cancer.

Scientists in Sweden found that the test can cut death rates from prostate cancer by as much as half when it's used to screen men between 50 and 65 years old.

But the findings don't necessarily mean that nationwide prostate screening programs should be introduced. That's because they can lead to the overdiagnosis of tumors.

The study is published in the online edition of The Lancet Oncology.
