Can you get an earlier colonoscopy ? I had noticed smaller diameter stools also. They found a tumor, looked like a polyp on steroids. It was cancerous. Had section of colon removed. They tested 22 lymph nodes and they came back clear. Oncology doctor said I didn't need chemo or radiation, but will monitor my blood work every three months and colonoscopy will happen every year. I did not have to have a temporary ostomy bag. I was dreading that. But I will have to accept reality of the outcome no matter what. I am now ( 2 months later ) testing for prostate cancer. I read what I can but get information overload. I am challenging the urologist and not winning any browie points doing so.
Please if you can, insist on a colonoscopy sooner. Time can make a difference. My tumor was growing quickly. Not to scare you just to make you aware. Do not put this off please. Keep writing.
