Not all basal cell cancers are harmless

basal cell cancers aren't always so harmless: True, the growths are usually easy to remove, but of the million new cases each year, about 5 to 10 percent can be resistant to treatment, recurring over and over and requiring more extensive surgery. And some basal cells can be very aggressive, damaging the skin around them and even invading bone and cartilage. That's why if you have a suspicious growth, you should see a doctor promptly. You want it removed before it disfigures your face.
