How long have you had the mass? Had it ever been biopsied? I’m curious because I have a large lipoma on my side…sort of on ribs. It’s been there for 20 years! When it first appeared, I had a surgeon examine it and do a biopsy, which was fine. Wish I had removed it then. Why, oh why didn’t someone encourage me to remove it then……anyway, it started bothering me this year and I had scheduled to have it removed, but had to cancel due to family emergency. Looking forward to getting it removed. Now, I am wondering if it might be more than just a lipoma. I asked the surgeon at my consultation about cancer and he said no way. Idk.
