Anal Swelling / Lump

Also called: Perianal Mass

An anal swelling or lump refers to any palpable mass or area of swelling around or just inside the anus. This common symptom can arise from various causes, ranging from the acute, painful presentation of a thrombosed hemorrhoid or a perianal abscess to the more chronic, often painless nature of skin tags or anal warts. While most causes are benign, a persistent lump can rarely be a sign of malignancy. Therefore, a thorough clinical evaluation is necessary to establish a precise diagnosis, as the treatment and urgency depend entirely on the underlying condition.

Frequently asked questions

Could my anal lump be cancer?
While the vast majority of anal lumps are caused by benign conditions, it is a possibility. Anal cancer can present as a hard, sometimes ulcerated lump. This is why it is essential that any persistent or unusual lump in the anal area be evaluated by a healthcare professional to get an accurate diagnosis.

The lump is very painful. What is the most likely cause?
A sudden, very painful lump right at the edge of the anus is most commonly a thrombosed external hemorrhoid. A painful, swollen, red lump that gets progressively worse, especially with a fever, is most likely a perianal abscess.
