Most are benign but they should always be checked out
Any swelling that suddenly becomes noticeable to you should be looked at by a doctor. Most swellings are usually innocent and not malignant, but it is foolish to ignore any lump or bump that wasn't there before.
Many swellings can be diagnosed by simple examination, whereas others may have to be examined by a specialist. They may X-ray or scan the affected part, and then probably remove the lump (lumpectomy), for closer inspection in the laboratory.
Lumps or swellings should never be left undiagnosed, especially breast lumps. Even if a swelling is cancerous, the earlier the cancer is caught the better the chance of a complete cure.
