What is Basal Cell Carcinoma?
Basal cell carcinoma (BCC) is the most common form of skin cancer in the U.S. It usually develops after years of sun exposure. Ultraviolet (UV) rays damage the skin, and that damage adds up over a lifetime. That’s why BCC is most often found on the parts of the body that get the most sun.
It helps to know a little about how your skin works. The top layer of your skin — called the epidermis — is made up mostly of three types of cells: basal cells, squamous cells, and melanocytes.
Basal cells are small, round cells found at the bottom of the epidermis. Think of them as the “basement” of your skin — which is why they’re sometimes called “basement cells.” They play a critical role in maintaining your skin tissue.
Basal cells are always making new skin cells. These new cells rise to the surface, renewing your skin as older, dying cells shed off. This steady cycle is essential for keeping skin healthy, repairing damage, and healing wounds.
BCC begins when basal cells grow out of control and become cancerous. Here’s the good news: BCC generally grows slowly, and it is usually very treatable — especially when it’s found early.
Having it diagnosed and removed promptly can keep it from growing larger and can protect your skin’s appearance. And while it’s rare for BCC to spread outside of the skin, it is possible. That’s why any spot you’re concerned about deserves prompt attention from your healthcare provider.
Frequently Asked Questions About Basal Cell Carcinoma
What does BCC look like?
It can look different from person to person — a sore that won’t heal, a scaly or irritated patch, a shiny bump, a waxy scar-like area, or a glossy dark growth with a rolled edge. If a spot is new or changing, it’s worth showing to your provider.
Is BCC serious? Can it spread?
BCC usually grows slowly and responds very well to treatment when it’s caught early. It rarely spreads beyond the skin, but it can happen — so any concerning spot deserves a prompt look.
Is BCC curable?
Yes — BCC is highly treatable, especially when found early. That’s why regular skin checks matter, and why any new or changing spot should be brought to your healthcare provider’s attention.
I’ve been diagnosed with BCC. What now?
Follow your provider’s treatment and follow-up plan. Having had BCC raises your chance of other skin cancers, so monthly self-checks and yearly full-body exams become even more important.
