Hi I'm isabel. My GP phoned me and told me my stool sample came back positive and she was sending me for a colonoscopy if that was OK. Previous to that I had full blood count taken and she said I had low iron storage but I wasn't anaemic and put me on ferrous fumerate which has caused me to be constipated. I had to strain to do the toilet so as I could put sample in. I have a consultation on Monday regarding my colonoscopy but I'm worried sick incase it's cancer. I had breast cancer 15 years ago had a lumpectomy and radiotherapy and put on tamoxifen for 10 years. I am now off everything and have been feeling fine but it's on my mind 24/7. Has anyone else felt the same
