Most skin cancers are caused by UV radiation, which means they are largely preventable — and highly treatable when caught early. Prevention has two halves: protecting your skin, and noticing change early. Here is how to do both. If something has already caught your eye, a doctor can review it for $49.
Protect your skin from UV
- Slip on protective clothing.
- Slop on SPF 50+ sunscreen — reapply every two hours, and after swimming or sweating.
- Slap on a broad-brimmed hat.
- Seek shade, especially in the middle of the day.
- Slide on sunglasses.
- Avoid sunburn — and never use tanning beds.
Catch problems early
The second half of prevention is early detection. Get to know your own skin so you notice a new or changing spot, do a self-check every few months, and have regular in-person checks if you are at higher risk. When something changes, don’t sit on it — get it reviewed.
Know the signs
Knowing what skin cancer looks like, when to worry about a mole, and which sun spots are harmless turns prevention into action — you catch the one spot that matters while it is still easy to treat.

Worried about a mole, mark or changing skin area?
Most skin-cancer advice tells you to watch for change. Skin360AI helps you keep photos of one or more spots connected over time. A spot can be a mole, freckle, mark, lump, sore, patch or any skin area you want to watch. It is not a diagnosis and cannot rule skin cancer in or out.
If a lesion is new, changing, bleeding, non-healing or worrying you, arrange an in-person GP or skin-cancer clinic assessment.
Check and watch the spots you care about over time
Use the free AI-assisted skin check to save photos of moles, marks, lumps, sores, patches or other skin areas you want to watch. A photo record is not a diagnosis or a cancer all-clear.
