Many people do not realize that skin cancer can occur on the foot. While it is rare, I do see it in my office. I do my best to educate my patients on what to look for, and explain that there is only one person who can tell if it is skin cancer – that person is a pathologist. You need to look at the cells under a microscope to determine if it is malignant, or cancerous.

Watch the video below to hear Dr. Campitelli discuss skin cancer on the foot:

There are four major things we look at to help determine if it needs biopsied. They are easily remembered by the acronym ABCD’s of skin cancer.

A – Asymmetry   

B – Border

C- Color

D – Diameter

Asymmetry – If you were to draw a line through the skin lesion, the sides should look the same.

Border – The borders should be regular and not jagged or irregular.

Color – The color should be regular and equal throughout

Diameter – The diameter or size of the lesion should be no larger than that of a pencil eraser.
