A sebaceous cyst is a small lump or bump on the skin which is non-cancerous. It is most frequently found on the face, neck, upper chest and upper back. However, cysts can occur anywhere else on the skin.
Usually, a sebaceous cyst grows gradually and does not cause any pain. However, they may become infected or inflamed. Additionally, the surrounding skin may turn red, sore, and tender.
A foul-smelling, cheese-like material may sometimes drain from your cyst. In these cases, treatment can reduce the discomfort you experience and improve the appearance of your skin.
How are Cysts Treated?
Cysts can be drained with a needle. Alternatively, they can also be injected with corticosteroids to help reduce the inflammation. If left untreated, a cyst can become an abscess – which poses the risk of bursting inside the body and causing blood poisoning.
