Thanks for consulting. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. kindly consult a general surgeon as a rectal examination needs to be made regarding the lump. some times a polyp also can present with similar features. based on the rectal examination the intervention can be planned. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
