What Should I Do If I Find a Lump between My Vulva and Anus?

If you find a lump between your vulva and anus, it is important to have it evaluated by a healthcare provider to determine its cause and decide whether treatment is needed.

Explanation

A lump in the area between your vulva and anus can be caused by many things. It might be a benign (noncancerous) growth such as a cyst, a fibroma, or other soft tissue lesion. Sometimes, it could also be a rare type of growth like a myxoid leiomyoma, which is typically not dangerous but should still be evaluated. Even if the lump does not hurt or bother you, having it checked by a healthcare professional is a wise decision. The provider will perform a physical examination and may recommend imaging tests like an ultrasound or MRI to elucidate the nature of the lump including the size and shape. In some cases, a small tissue sample (biopsy) might be taken to confirm the diagnosis. Checking out the lump will help rule out any serious conditions and provide reassurance if it is benign. Early evaluation ensures that you get the proper care and treatment if needed.
