I had a sudden heavy bleed from my rectum yesterday .it was more like a large dark tarry clot . Became very weak .was taken to hospital . While there I had several episodes of urgency to go to the loo which produced blood with lots of blackish clots . CT scan was clear . Bloods ok . Haemorrhoids we re suggested but I am very sceptical as there was so much blood . Going for colonoscopy on Wednesday . What do you think ?
Thanks for your question on Chat Doctor. Since your CT abdomen is normal, possibility of mass is less likely. But bleeding from rectal and that too large suggest malignant involvement only. In early cases mass has not formed, but mucosal irregularities can give rise to bleeding and mass in the future. And this can not be identified by CT scan. We need to do colonoscopy for this and biopsy from suspicious lesion will confirm the diagnosis. So you may have early malignancy. Get fans colonoscopy.
