If you find a small lump near the anus, it's important to have it checked by a healthcare provider to make sure it isn’t a sign of something more serious, such as an infection or, rarely, a malignancy.
A small lump near the anus can sometimes be harmless, but there are several possibilities. It might be due to a minor infection, like a small abscess, or it could be a benign growth such as a hemorrhoid or skin tag. In some cases, although less common, lumps near the anus can be related to early signs of anal or perianal skin malignancies. Regardless, any new or unexplained lump should be evaluated. Usually, a doctor will begin with a physical exam to look at the lump’s size, shape, and tenderness. They might ask about any symptoms like pain, bleeding, or changes in the area. In addition, imaging tests or even a biopsy might be recommended if there are any concerns about the nature of the lump. Early evaluation helps rule out serious conditions and ensures you receive the right treatment if needed. Even if the lump is not causing discomfort, it is wise to get a professional opinion to have peace of mind and proper care.
