Last week I was referred for urgent cancer screening as blood was in my poo test and experiencing other symptoms. Yesterday I had the colonoscopy the man that done it asked me why I was here and I said my doctor referred to you because of blood found in my stool samples and other symptoms. He laughed and said ‘ nothing will be wrong’ indicating because of my age. I had it done and when I was waiting the nurse come and spoke to me and said the colonoscopy was normal just an anal fissure was detected. But on my report it says 12 biopsy’s were taken and I remember seeing that on the screen. Does anyone know why they would take these biopsy’s and why so many?
