I’m worried this maybe is cancer? I’ve had this on my thigh for a couple of years. (Photo)

It is very hard to see the lesion from the photo you have sent.  If they are red and regular, they most probably are vascular in nature, however, you will not be completely sure until you have seen your own doctor.

An In Person evaluation is needed in order to determine if there is an infection present, I suggest following up with the physician who performed the mole removal. Best, Dr. Emer. 

Hi!! You first need to get the moles checked by a dermatologist to make sure they are benign. Moles can be removed using electrocautery which leaves minimal scarring if done by an experienced dermatologist. 

Hello djohnkinman.  It would be a lot easier to answer this question if you provided pictures to be able to see how big and/or deep your incisions were.  It would also be helpful to know what technique was used to close your incisions and how long after biopsy that your sutures were...

I don't recommend attempting to remove moles yourself. I recommend getting a formal evaluation with a cosmetic dermatologist. Moles can be removed with laser, radiowave or shave. See an expert. Best, Dr. Emer

I recommend getting a formal evaluation with a cosmetic dermatologist for after care. I recommend Silagen + Bioshield to promote healing. Any scar can be improved with lasers (ProYellow, Excel V, VBeam) and microneedling/prp. See an expert. Best, Dr. Emer
