What it is
Most cysts do not need treatment and may go away by themselves. Do not squeeze them.
A cyst that is infected, painful or in an awkward place can be removed with a small operation.
Common signs
- A smooth, round lump under the skin
- A lump that moves slightly when pressed
- A small dark spot in the centre
- Redness, pain and swelling if it becomes infected
How it is usually diagnosed
- Looking at and feeling the lump
- Sometimes an ultrasound scan
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- GP or dermatology notes
- Ultrasound reports
- Minor surgery and pathology reports
Questions to ask your doctor
- Is this definitely a cyst?
- Does it need to be removed?
- What should I do if it becomes infected?
When to get help right away
Call 112 or go to the nearest emergency department if you have:
- A lump that grows quickly, is hard and fixed, or comes back after removal: see a GP soon
