A sebaceous cyst is a small non-cancerous lump or bump on the skin. It is usually found on the face, neck, upper chest and upper back but can also appear on other parts of the body.
It develops gradually, and there is no pain. A sebaceous cyst can, however, become infected or inflamed and sometimes emit a foul odour, sometimes with an accompanying discharge of a cheese-like substance. The
inflammation can cause the skin to be tender and sore. A treatment to address this issue is often recommended to alleviate discomfort and improve skin’s appearance.
