Re: Lump on top of my left ribcage
Based on my research, if it's hard, painless, immovable, and has irregular edges, it *may* be cancer, but those are general guidelines and not hard, fast rules. Based on your description of it, it's probably either a 1) strain or tear of a muscle and/or tendon and/or 2) an infection and/or abscess. Either way, please get it checked out by your doctor to rule out it being anything serious.
