[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion, you should consult doctor and get done clinical examination of your anus. Because we need to rule out local recurrence of anal cancer. Boil can also be the possibility in your case. Chemotherapy and local radiotherapy make patient immunocompromised and hence infections are common. So better to consult doctor and rule out infection and local recurrence. You may need biopsy of that lump with histopathological examination to confirm the diagnosis. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
