I am a 32 year old man. I've had a lipoma near my left ribcage for 15 years. It has grown very slowly in that time and there has never been any pain, symptoms related. No other health problems. I am having the lipoma removed next week, and during the consultation the dr. said she doesn't expect anything negative. Still, I'm nervous about the biopsy. Given how long I've had it, with no symptoms and normal blood work, it's probably unlikely to be something more serious than lipoma, right?
