Screening increase leading to unneeded surgeries?

Two new studies question whether an increase in prostate and breast cancer screenings are leading to unnecessary treatments and surgeries. Research in the Journal of the National Cancer Institute says more than 1 million US men have been diagnosed with tumors that may have never caused any problems.

Researchers say the PSA test is a double-edged sword, catching serious cancers in a few but causing needless worry and expense for a majority.

Another report looked at combining mammograms and clinical breast exams.

Slightly more cancers were caught with the combo but the number of false positives was substantially higher.

Still, most women said they would rather get a false scare than a delayed diagnosis.
