A small, hard, bony-feeling swelling on the scalp that has been present for 8–10 months without pain, change in size, redness, or other symptoms is most commonly benign and not serious. In many cases, such lumps are due to conditions like a small osteoma (benign bony growth), a calcified cyst, or a benign scalp cyst that becomes firm over time. These types of swellings usually grow very slowly or remain stable for years and often do not require treatment if they are not causing discomfort.
The reassuring points in your case are that the swelling is not painful, has not rapidly increased in size, and is not associated with skin changes, fever, or neurological symptoms. However, since it feels bony and has persisted for several months, the best way to confirm the diagnosis is with a simple clinical examination and, if needed, an ultrasound or X-ray/CT scan of the skull. These tests can easily determine whether it is a harmless bony prominence or another benign scalp lesion.
In most cases like this, no treatment is required, and removal is considered only if the swelling increases in size, becomes painful, or causes cosmetic concern. If you notice rapid growth, tenderness, redness, headache, or neurological symptoms, then you should seek medical evaluation promptly. Otherwise, it is very likely to be a benign, stable finding.
Good luck and do contact in case of any doubt.
