Dangers of Lipoma on the Scalp?

Lipoma removal on the scalp can be removed and is not dangerous if it is in fact a lipoma.  Rare cases of fatty tumors have been described.  Most often it is removed under local anesthesia comfortably and best to have a lipoma removed with a minimal incision.  Best Anil Shah

Lipomas are not “dangerous” per se.  However, the only way to get a confirmed diagnosis is to send the specimen to the pathology lab.  There are infrequent cases of liposarcoma which is a bona fide cancer.  The other problems with lipomas is that they can get much larger and they do not go away on their own.  I have taken many off of the scalp as well as virtually every other area of the body.  Depending on the size and location you may be able to have the procedure with only local anesthesia.

If a lump on the scalp is truly a benign lipoma, the only real danger would be a cosmetic deformity, but there is no way to know if a lesion is truly benign without removing it for analysis by the pathologist. Surgical excision of lipomas is usually straightforward and involved making an incision over the lipoma. The lipoma is then removed by dissecting it safely away from the normal surrounding structures. The risks of lipoma removal would be similar to most any other surgical procedure, and would include bleeding, scarring, infection, numbness, and the need for future surgery.
While lipomas on the body are more common than lipomas on the scalp, I would not consider lipomas on the scalp to be rare - it is something I see in my practice relatively frequently.
