Hi. Can you provide some additional descriptions of that lump? Is it movable or is it fixed against the surrounding tissue? What is its consistency? Hard and bony like your ribs? Or soft and jelly-like? It's too early to tell at this point what that lump is, but if it's soft and movable, it may be a non-cancerous condition like a lipoma (a lump consisting of fat cells) or an epidermal inclusion cyst (an accumulation of oily secretions from skin glands that have been blocked). The best thing for you to do is to have it examined by a doctor. Feel free to post if there are any further developments.
The lump is movable by a couple of inches. It isn't hard like a bone, but not soft either. It feels sort of like a node behind your ear or something like that.
Hi. Thanks for the additional input. You may need to have a biopsy of that lump done to make sure that it isn't anything serious. From your age alone, and from the fact that the lump is movable and not fixed on surrounding structures, we can say that the lump is not likely malignant. But only through a biopsy can we know for sure whether it is or isn't.
