To Cut or not to cut

Recently, my dermatologist did a skin biopsy on my left forearm (via incision, not just a scraping) and a diagnosis of seborrheic keratosis was made.  He said it is pre-cancerous and I could either do nothing or have it removed by a surgeon.  The lesion is about 5 mm in size.  He told me that he strongly recommends to have it cut out and not "wait until it becomes a cancer".
Is surgery really necessary?  A) I am worried about a scar in a very noticable location, and B) I have at least one other lesionon that looks like it.  Is there another form of treatment?
I do not want to cut if not absolutely necessary.  What are the statistics for seborrheic keratosis becoming malignant?
Thank you.

Seborrheic keratoses do not become malignant.  They do not need to be excised--they can be removed by scraping if desired, and that doesn't scar.  The story you tell doesn't make a lot of sense.  If you're sure you're quoting the diagnosis accurately, then you should get another opinion.

Best.
