There's more advice on the issue of prostate cancer screening.
A leading group of cancer specialists says the decision hinges, in part, on a man's life expectancy.
They say doctors should discuss the pros and cons of PSA blood tests only with men expected to live at least 10 more years.
They also say the risks of the tests outweigh the benefits for men who aren't expected to live that long.
In contrast, a government task force recently recommended against routine PSA screening for all men.
