Is the mole on the areola indicative of cancer as per the attached image?
Looks normal to me
Hi and welcome. I've reviewed the image.
It is not unusual to have moles in the periareolar area. Well as I can see from this photo it looks to me like acquired melanocyte nevus which is the name for benign moles.
Although this is bit darker, there are no other features of dysplasia and I don't think you should be concerned especially if this area is not exposed to the sun often.
You can always have it checked or removed to ease your mind but I don't think this is required at this point.
Wish you good health.
