Basal cell carcinoma (BCC) is the most common and usually the least dangerous type of skin cancer. BCCs usually appear on the face, neck, back or shoulders. BCCs start in the basal cells of the skin’s top layer (the epidermis). They grow slowly over months or years and rarely spread to other parts of the body.This table summarizes the number and type of interstitial sites for simple cubic, body-centered cubic, face-centered cubic, and hexagonal close-packed crystals.
