Hi all I have had radiotherapy and hormone injections for advanced prostate cancer and finished approximately two years ago, I now have had diarrhoea for a couple of months and have some stomach pain with this I get a pain then have about 1/3 minutes to get to a toilet, my doctor has had a stool sample and blood taken and a colonoscopy nothing found can my prostate cancer be a factor with theses symptoms. Any thoughts would be appreciated. Richard.
