Skin Cancer: What You Need to Know

Skin cancer is the most common cancer in the world, but most people don’t realize they’re at risk. It starts when UV light from the sun or tanning beds damages the DNA in skin cells. If the damage isn’t repaired, cells can grow out of control and form a tumor. The good news is that early detection and simple lifestyle changes can keep the odds low.

Common Types and Warning Signs

There are three main types you’ll hear about: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. BCC and SCC usually appear as a firm, raised bump or a scaly patch that won’t heal. Melanoma looks like a new mole or a change in an existing one. Use the ABCDE rule to spot it – Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, and Evolving shape or size. If something looks odd, get a doctor to check it right away.

Other signs to watch for include itching, bleeding, or a sore that keeps coming back. Even a small change can matter, because skin cancers grow fast on sun‑exposed areas like the face, neck, arms, and hands. Don’t wait for pain; most skin cancers are painless in the early stages.

How to Reduce Your Risk

Protecting your skin is easier than you think. Slip on a shirt with long sleeves, wear a wide‑brim hat, and use sunscreen with at least SPF 30 every day. Reapply every two hours, especially if you’re swimming or sweating. Seek shade between 10 a.m. and 4 p.m., when the sun’s rays are strongest.

Avoid indoor tanning – the UV light is just as harmful as midday sun. If you’ve had a severe sunburn, keep an eye on that spot for weeks. Regular skin checks, either at home with a mirror or by a dermatologist, catch problems before they spread.

Family history matters, too. If close relatives have had skin cancer, you’re more likely to develop it. Talk to your doctor about a personal screening schedule. For fair‑skinned people, a yearly full‑body exam is a smart move.
