Thanks for the query.

The lump that you describe could be a neurofibroma/lipoma. A physical examination by a surgeon will confirm.

Neurofibroma / lipoma is basically a lump of fibrous tissue/adipose tissue. Its not cancerous and not harmful. Surgical removal is sometimes needed when there is function impairment or when you develop symptoms.

I suggest you to see your doctor for localised examination of the lump. You may plan the necessary procedure after discussing with them.

Hope I have answered your query. Should you have any additional concerns I will be available to clarify them.

I just wanted to add that it is not visible it is noticeable only to the touch. I am afraid of a bone cancer?

Hi again,
From your description bone cancer is unlikely.Bone cancer affects the bone and isnt felt on touch. There is a lot of muscle and tissue between the skin and the bone.

Its more likely to be the possibilities i have already mentioned.
