What is Basal Cell Carcinoma?
Basal cell carcinoma (BCC) is a type of skin cancer that begins in the basal cells—the cells at the bottom of the epidermis that produce new skin cells. It's the most common cancer in humans, with millions of cases diagnosed each year.
The good news: BCC is highly treatable, especially when caught early. It rarely spreads to other parts of the body, but if left untreated, it can grow deep into tissue, causing significant local damage.
Types of Basal Cell Carcinoma
Nodular BCC
Shiny, dome-shaped bump, often pearly or pink. May have visible blood vessels. Most common type.
Superficial BCC
Flat, reddish, scaly patch that may resemble eczema or psoriasis. Often on trunk.
Morpheaform BCC
Waxy, scar-like area with poorly defined borders. Can be skin-colored or white. Most aggressive subtype.
Pigmented BCC
Dark brown or black coloring within the lesion. Can be mistaken for melanoma.
