July 23, 2012 at 10:33 pm #55651 Catherine PooleKeymaster Yes, I believe so, but I would verify with your doctor what he/she means. Lesions are normally what you find outside of the body, not internally. July 24, 2012 at 11:00 pm #55652 Mrs_RasParticipant Gary’s onc said lesions are the same thing as tumors. That means he has about 15 tumors, not including the 162 nodules he has up and down his left side, his back, leg and groin.
