Skin Cancer: Signs, Prevention & When to See a Doctor
Skin cancer happens when skin cells grow out of control. The most common kinds are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal and squamous cancers grow slowly and are usually treatable. Melanoma is less common but more likely to spread. Knowing what to watch for and how to protect your skin makes a big difference.
How to spot trouble early
Want a simple rule to remember? Check your skin once a month and look for anything new or changing. Use good light and a mirror or ask someone to check hard-to-see areas. The ABCDE rule helps with moles and spots:
- A — Asymmetry: one half doesn’t match the other.
- B — Border: edges are uneven, notched, or blurred.
- C — Color: multiple colors or a very dark spot.
- D — Diameter: larger than 6 mm (about a pencil eraser), though smaller can be a problem.
- E — Evolving: any change in size, shape, color, or symptoms like bleeding or itching.
Also watch for: a sore that won’t heal, a scaly patch, a pearly bump, or any spot that hurts, bleeds, or looks different from your other moles. If a spot keeps coming back after treatment, get it checked again.
Practical prevention & next steps
Sunscreen and smart habits reduce risk. Use a broad-spectrum sunscreen SPF 30 or higher and reapply every two hours, or after swimming or sweating. Wear a wide-brim hat, sunglasses, and tightly woven clothing when you're in strong sun. Avoid tanning beds — they raise your risk a lot. Try to stay out of direct sun between 10 a.m. and 4 p.m.
Some people need more frequent checks: those with fair skin, many moles, a family history of melanoma, lots of sunburns earlier in life, or a weakened immune system. If that sounds like you, ask your doctor about regular skin exams.
What happens if your doctor is worried? They usually remove or biopsy the spot to get a clear diagnosis. Early-stage cancers are often treated with simple procedures that remove the growth. More advanced cases may need surgery, targeted therapy, or immunotherapy—your dermatologist or surgeon will explain the best option.
If you find a changing mole, new lump, or a sore that won’t heal, don’t wait. Book a primary care or dermatologist appointment. Catching skin cancer early usually means simpler treatment and better results.
Quick checklist: do a monthly self-check, use SPF 30+, avoid tanning beds, wear protective clothing, and see a doctor for any changing or unusual spots.
