Basal Cell Carcinoma: Causes, Signs, and What You Need to Know

When you see a spot on your skin that won’t go away—a pearly bump, a scaly patch, or a sore that bleeds and heals over and over—it might be basal cell carcinoma, the most common form of skin cancer that starts in the basal cells of the epidermis. Also known as BCC, it rarely spreads to other parts of the body but can grow deep and damage surrounding tissue if left untreated. Unlike melanoma, it doesn’t get as much attention, but it affects over 4 million people in the U.S. every year. Most cases happen on areas exposed to the sun—face, neck, ears, scalp, and back of the hands.

What causes it? UV radiation, from sunlight or tanning beds. This damage builds up over time, even if you never got a bad sunburn. People with fair skin, light eyes, or a history of sunburns are at higher risk, but it can happen to anyone. Dermatology, the medical field focused on skin health, is where you’ll get the right diagnosis. A simple skin biopsy can confirm if it’s basal cell carcinoma or something else, like eczema or psoriasis.

It doesn’t always look scary. Some forms look like a pimple that won’t heal. Others appear as a flat, scaly red patch or a waxy scar-like area. You might not feel pain, which is why people ignore them. But if it’s changing in size, color, or texture, don’t wait. Early treatment—like topical creams, freezing, or minor surgery—works best and leaves minimal scarring.

The good news? Most basal cell carcinomas are caught early. The key is knowing what to look for and checking your skin regularly. This collection of posts gives you real, practical advice—from recognizing early signs to understanding treatment options and how medications might affect your skin. You’ll find insights on how certain drugs influence skin health, what to ask your doctor, and how to protect yourself long-term. No fluff. Just what works.
