A few days ago husband found a lump about the size of a hard pea under the skin in his abdomin... about 5-7 inches right of his belly button. He has a fatty cyst/tumor on his back, and this new lump feels nothing like that. It is very hard and doesn't move much, the skin seems to move over it, but it stays stationary. It is near several large moles. 1 is large, raised and round the other is dark, VERY large, only slightly raised and very irregular borders. I don't know if it could be at all related to the moles, but thought it could be helpful knowledge if needed.
Please advise what he should do or if it is something to not be concerned with. He does NOT have a dermatologist. Which I know he should see one for his moles.
