My hubby who is 50years old 190lbs, 5'10" tall, had anal cancer. In Sept 2009, treatments included a pic-cath for 2 96 hour treatments and 30 zaps of radiation (which severely burned him) The treatments were from Oct 2009 to Dec 2009. He seems to be doing ok but the doctors never really gave him the "all-clear" or declared him cancer free. He has been eating a lot of nuts which he knows he is not suppose to and two days ago during a bowel movement, he had what he stated " a load" of blood pass. He is believing this is from eating to nuts and his anal walls being thinner from the radiation. Can you please advise on this?
