What?? White fluffy tissue with blood spot

please help. Been seeing this during daily enema for a week. Had colonoscopy done a year ago and they found and removed a precancerous tumor. Have had cervical cancer at 46...now 48...radical hysterectomy and 25 radiation treatments. I am very concerned. Also...have done enemas for 6 months now and seem to not be able to hold them like I used to could. At about 10 to 12 inches in I feel resistance like a turn or polyp??? Used to go . 4 inches max but now only about 10 inches. Go to doc tomorrow but trying to get educated. People here are fabulous...God bless every one here! Tweet
