[|Human|] My 26yo son is in hospital with low heamaglobin he had a colonoscopy last friday and they found a 50cent coin lodged in his bowel which has been there for over a year (he thought it had passed) at the lodgement site they found a large mass behind the coin which is being tested as they dont know what it is. Can the coin lodgement cause bowel cancer?
[|AI|]  Hi and welcome to Chat Doctor. Thanks for the query. Basically it can't cause cancer. It can cause granulomas or fibrous tumors if there was inflammation around this coin. These are benign structures which extremely rarely can alternate to malignancy. But if it continues to grow it may cause bowel obstruction so you should be aware of it and if this happens surgery may be necessary. Wish you good health. Regards
