A vigilant reader sent me a copy of this notice.  There are still a few days to take advantage.  Urge all your acquaintances to get tested.  And congratulations to the Chicago Sun-Times for offering this life-saving service.

The prostate cancer-detecting PSA blood test, which measures levels of prostate-specific antigen, will be offered for free throughout the Chicago area April 21-26 by the Sun-Times, the National Prostate Cancer Coalition and several local hospitals.
