Quick answer
What is Skin cyst?
A skin cyst (commonly called a sebaceous or, more accurately, an epidermoid cyst) is a smooth, round lump just under the skin, filled with a soft, cheesy material (keratin). They are very common and harmless (non-cancerous).
- How it is treated: Most skin cysts need no treatment and are simply left alone, especially if they cause no problems.
- Self-care: Avoiding squeezing or picking at a cyst prevents inflammation, infection and scarring.
- When to seek help: See a GP if a cyst becomes red, painful, swollen or infected, keeps recurring, or is bothersome and you would like it removed.
What it is
A skin cyst (commonly called a sebaceous or, more accurately, an epidermoid cyst) is a smooth, round lump just under the skin, filled with a soft, cheesy material (keratin). They are very common and harmless (non-cancerous). They often have a small dark central opening (a punctum), and can sometimes release a thick, unpleasant-smelling substance. They grow slowly and can appear on the face, neck, trunk, back and genitals. Most cause no problems, but a cyst can become inflamed, tender and red, or infected, forming an abscess. Cysts can also become larger over time. They are usually diagnosed by their typical appearance and feel. As with any lump, features that are unusual — such as rapid growth, hardness, or being fixed — should be assessed.
How it is treated
Most skin cysts need no treatment and are simply left alone, especially if they cause no problems. It is best not to squeeze or pick at a cyst, as this can cause inflammation, infection and scarring. If a cyst becomes inflamed or infected, it is treated accordingly — an infected or abscessed cyst may need draining and, sometimes, antibiotics. A cyst that is bothersome, keeps getting infected, or is in an awkward spot can be removed by a minor operation, ideally when it is not inflamed, which usually involves removing the whole cyst lining to reduce the chance of it coming back. If a cyst has unusual features, it may be examined more closely. Care is usually guided by a GP, with referral if needed.

Beyond medication
Lifestyle and self-care
Avoiding squeezing or picking at a cyst prevents inflammation, infection and scarring. Good skin hygiene helps. Having a bothersome or repeatedly infected cyst assessed allows planned removal when it is not inflamed.
When to get help
When to see a doctor
See a GP if a cyst becomes red, painful, swollen or infected, keeps recurring, or is bothersome and you would like it removed. Have any lump with unusual features (hard, fixed, rapidly growing) checked.

Answers
Skin cyst: frequently asked questions
Should I squeeze a skin cyst?
No — squeezing or picking at a cyst can cause inflammation, infection and scarring, and often does not remove it. If a cyst is bothersome, a doctor can remove it properly, ideally when it is not inflamed.
Are skin cysts dangerous?
No — they are harmless, non-cancerous lumps. They can occasionally become inflamed or infected, which is treatable. Any lump with unusual features should be checked to be sure.
