4 years ago I had hormone and radiotherapy and my PSA is now 0.07. I was given the choice of surgery at the time and found it a really hard choice but at 70 years of age I was worried about side effects like incontinence so chose the 20 sessions of radiotherapy. I havent been too bad over the years but recently started to experience fatigue again and when my gp requested a poo test the reading came back raised and yesterday I had a CT colonoscopy to check for possible colon cancer. I'm now nervously waiting for results. I just remember reading that there was a small risk of this with radiotherapy something like 2 %. and so I agreed to the spacer gell being inserted to protect the rectum. I now find myself regretting not having surgery but of course its too late. Just wondering if anyone has had a similar experience .
