Two other reports presented at the meeting revealed favorable results about proton therapy, in which prostate cancer is attacked by a beam of protons rather than X-rays. Physicians at the University of Florida in Jacksonville reported that proton therapy did not appear to have harmful effects to the urinary system, which had been feared. And a study at Loma Linda University in California found that a booster round of proton therapy reduced recurrence of prostate cancer in men who first had X-ray treatment.
