From the Nov. 2008 Urology Times:

Univ. Calif. Davis researchers report patients treated with radiation for initial therapy for prostate cancer, and men treated with radiation for positive margins at radical prostatectomy have a 2-fold risk for developing subsequent bladder or colorectal cancers due to the radiation exposure.

Caution was urged as there are trends towards treating the positive margins before any rise in PSA confirms residual cancer.

Additionally, at the 2009 American Urology Assn meeting, stats were quoted describing a risk of 1% per year of developing a secondary cancer in the bladder or rectum due to radiation exposure.
