At this age group cancer is less likely It may be due to piles or even chronic fissure Kindly consult a surgeon at your locality for physical examination and proctoscopy or else online with Dr Pandian

Its mostly due to haemorrhoids, so prior to colonoscopy take medications & look whether decreasing or not.
