(American Journal of Public Health) -- Even though prostate cancer screening is touted as an important tool to help save men's lives, most men may not understand the risks or effectiveness associated with the procedure.

According to a survey of 271 Texas men, more than half were planning to have a PSA (prostate-specific antigen) screening test, but 60 percent were uninformed about some aspect of the test.

The test is controversial in public health and medical circles because of a lack of data on its effectiveness in reducing cancer deaths and such side effects of cancer treatment as impotence and urinary leakage.

The study's authors suggested further study into the issue using a larger study sample and public information campaigns that stress informed decision making.
