A small, "pea-sized" nodule under the skin is most often a lipoma. A lipoma is a fatty tumor, and I cannot ever recall reading or hearing of a malignant lipoma, so it is most likely benign. A dermatologist can easily inspect and either biopsy or remove this nodule.
would it come about as a result of my surgery?
i didn't have it before my surgery.
well, that's good news - it isn't a big deal.
I had something similar after my TAH. The scar was a pretty good length running from above and around my belly button to just above my pubic bone. There were several 'bumps' along the length of the scar. I don't have much belly fat so I could see and feel them when I lay flat on my back. They turned out to be ligatures and one actually had to be cut out. I still have the piece which is about 3/4 of on inch long. My understanding is that they normally lay flat and don't cause any trouble. In my case they popped up. Have your surgeon take a look the bump just to be sure everything is okay. Hope this helps.
My 6 month old daughter has the same type bump on the inside of her left hand, right on the index finger bone. It feels just like a BB. Is this the same thing?
