Sebaceous cysts, commonly known as just cysts, are small, closed sacs that contain solid or fluid material and can be found anywhere on the skin. They develop as an infection, often from a swollen hair follicle, and require treatment to prevent it from enlarging or becoming cancerous.
Cyst removal is done through surgical excision. A small incision is made in the area of the cyst and then the cyst and surrounding tissue will be removed to ensure complete excision. A local anesthetic is used for this procedure. Most cysts do not return when thoroughly removed. Some patients are left with a small scar after a cyst is removed, which can be further treated with a reconstructive treatment, although most scars will fade over time.
