SubicSquid,
Sorry to hear you may be joining the IMRT Club but with two positive margins you have a very good chance your cancer is local and they can get it with radiation. However, I think I would get another PSA in a month or so since 0.15 is still low, mine was 0.5 before I started treatment. You are only out 3 months and need time to heal and get the incontinence under control if possible before starting radiation.
