Summary

This study compares two ways of giving proton radiation to men with low-risk prostate cancer. One group gets the standard 44 treatments over about 9 weeks, while the other gets just 5 treatments over 1-2 weeks. The goal is to see if the shorter course works as well at keeping the cancer from coming back, with similar side effects.
