How to Tell if Mole is Cancerous?

Mole removal begins with a comprehensive examination and consultation to determine the likelihood of a mole being worrisome. Excisional and incisional biopsies are reserved for suspicious moles. But it’s good news that most moles are not problematic and are only cosmetic, thus leading to the option of scarless or non-surgical mole removal with lasers and RF and plasma. Our office specializes in non-surgical mole removal.

I would encourage you to allow the lesion to heal and then carefully have it evaluated.  When evaluating a mole/lesion for skin cancer we refer to the ABCD's of melanoma.  The only way to know if a lesion cancerous or not is to get a biopsy.

Dr. Ebrahim checks suspicious moles using the ABCD rule: 
Asymmetry

Border

Color or color change

Diameter – diameter larger than .06 mm

Evolution of the mole- changing or evolving

Dr. Ebrahim, in her Dermatology clinic uses Dermoscopy to evaluate moles.  The dermatascope provides

10 times magnification which  allows her to see deeper structures of the mole.  Dr. Ebrahim recommends that you have any suspicious moles evaluated by a Physician for peace of mind. 

The only way to tell if a mole is cancerous is to find an experienced board certified dermatologist with a knowledge of skin cancer.  It sounds like the mole needs to be sent to the pathology lab to determine what exactly it is.  Try not to scratch it because this can make it appear more irritated or infected.

It would be a wonderful thing if we could know who are enemies are but just looking at them. Unfortunately, all the "bad" guys do not wear black hats, wear black sunglasses or stroke a white Persian cat while laughing demonically.  To recognize many skin moles based on their appearance requires years of medical training and seeing thousands of moles. But even then, surgeons may underestimate a and mistake a mole thinking it is benign when in fact it could be a cancer.

The BEST way to tell what a mole is is to have is removed surgically and have a trained skin Pathologist examine it under the microscope. This will almost always pick an early cancer and prevent a delay in treatment. Anything less than this is a bet that the mole is benign and a compromise of your care. I would have it biopsied by a dermatologist or a Plastic surgeon.
