Treatment:

Sebaceous cysts are not dangerous and can usually be ignored. Placing a warm moist cloth (compress) over the area may help the cyst drain and heal.

If you have a small inflamed cyst, your doctor may inject it with a steroid medicine that reduces swelling.

If the cyst becomes swollen, tender, or large, your doctor may drain it or perform surgery to remove it.

Expectations (prognosis):

Large, painful cysts may interfere with day-to-day life.

Complications:

These cysts may occasionally become infected and form painful abscesses.

The cysts may return after they are surgically removed.

Calling your health care provider:

Call your health care provider if you notice any new growths on your body. Although cysts are not dangerous, your doctor should examine you for signs of skin cancer.
