Should I be concerned about bump at incision site from lipo 20 years ago? (Photos)

Thank you for your question. I would recommend just following up with your Surgeon and or a Dermatologist just to evaluate it. Best of luck to you.

Dear BSpirit,
it is hard to tell for sure without an examination. If you are considering treatment, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

I would let your medical doctor examine this. This is not from liposuction 20 years ago, but could be a small cyst or even a fatty tumor.

Thank you, BSpirit for your question and photographs.
Photographic evaluation is incomplete without personal examination to give a most appropriate answer
However from the photographs, it seems that,
It may be some hypertropic scar and is harmless.If you don't have any cosmetic concern then you don't need any treatment.

However please consult a board-certified plastic surgeon near you and discuss this in detail.
Wish you an alluring look.

It's difficult to say what may be the cause of the bump since your surgery was so long ago. I encourage you to have the area evaluated by a board certified plastic surgeon or your primary care physician for diagnosis. It may just be a little area of scar tissue.

Your skin growth is not related to Liposuction.
You can run it by your primary care doctor or see a dermatologist. To me it looks like a dermatofibroma or a benign mole a.k.a. nevus.
