Most of us know to wear sunscreen and avoid tanning beds, but when it comes to actually recognizing the signs of skin cancer, the truth is… many people don’t know what to look for. And that’s a problem. Because the earlier skin cancer is caught, the easier it is to treat.
What Does Skin Cancer Look Like?
So, what does skin cancer really look like? It’s not always as obvious as a scary-looking mole. In fact, some signs might seem so harmless, you’d never guess they were dangerous. Here’s what you need to know — and what you absolutely shouldn’t ignore.
1. A New Spot That Wasn’t There Before
It could be a freckle, a mole, or a tiny bump. If you notice something new on your skin — especially if you’re over 30 — it’s worth watching. New skin growths can be totally harmless, but they can also be early warning signs of skin cancer.
Quick Tip: Take a photo when you first notice it. That way, you can track changes over time.
2. A Mole That Changes Shape, Size, or Color
This one’s important. If you’ve had a mole for years and it suddenly starts growing, changing color, or developing an irregular border, don’t brush it off. These changes are red flags for melanoma, the deadliest form of skin cancer.
Pro Tip: Dermatologists recommend using the ABCDE rule:
Asymmetry
Border irregularity
Color variation
Diameter over 6mm
Evolving over time
If your mole hits any of those points, get it checked.
3. A Sore That Won’t Heal
We all get little cuts or blemishes that take time to fade. But if you have a sore or scab that just doesn’t heal — or heals and comes back in the same spot — it could be a sign of basal or squamous cell carcinoma. These are two of the most common (and treatable) types of skin cancer.
4. Itchy or Bleeding Spots
An itchy patch that won’t go away, or a mole that randomly starts bleeding? These can both be symptoms of something more serious. Don’t wait for it to get worse. When skin cancer causes irritation, it’s often because it’s growing or affecting nearby tissues.
5. Waxy or Shiny Bumps
Some skin cancers appear as small, pearly or waxy-looking bumps — especially on the face, neck, or ears. They may look like nothing at first, but they can grow beneath the surface and cause long-term damage if ignored.
So, When Should You See a Doctor?
If anything on your skin seems odd, different, or just “off” — go see a dermatologist. Even if it turns out to be nothing, peace of mind is worth it.
And here’s the kicker: skin cancer is one of the most preventable cancers out there. Sun protection, regular self-checks, and early detection can make a world of difference.
Look Closely. Stay Safe.
Most people don’t think twice about that spot on their shoulder or that dry patch on their nose — until it’s too late. But you don’t have to be one of them.
