Once the doctor knows what it is, the skin is cleaned and numbed with a local anaesthetic before any treatment begins.
A cyst can be opened and emptied, then its sac removed, while a lipoma is lifted out through a small incision in one piece.
Either way, the procedure is usually quick, and most people go home the same day with just a dressing on the shoulder.
Keeping the wound clean and avoiding heavy lifting for a few days helps it heal into a thin, barely visible line.
If something new appears on your body, get it checked. The videos below show shoulder lumps being examined and removed by professionals.
