The signs that mean “get it checked”
New
a new, unusual spot
Changing
size, shape or colour
Growing
getting bigger
Bleeding
or crusting, or itching
Won’t heal
a sore that keeps returning
Any one of these is worth a doctor’s eye — skin cancer is often painless early on.

The scalp catches a surprising amount of sun — especially with short or thinning hair — and is one of the easiest places to miss a skin cancer, simply because you cannot see it. If a spot on your scalp is worrying you, a doctor can review a photo of it for $49 and tell you whether it needs an in-person look.

What to look for on the scalp

The warning signs are the same anywhere on the body — a spot that is new, changing, growing, bleeding, or will not heal, or a mole that stands out from your others. On the scalp, watch especially for:

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.

Frequently asked questions

Is skin cancer on the scalp common?

It is a common and easily missed site, particularly in people with thinning hair or a history of sun exposure, because the scalp is hard to see and often unprotected.

What does scalp skin cancer look like?

Often a rough or scaly patch, a sore that will not heal, a pearly bump, or a new or changing mole. It can be felt (for example when combing or washing hair) before it is seen.

How do I check my own scalp?

Part your hair in sections in front of a mirror, use a second mirror or your phone camera, or ask a partner or hairdresser to look. A doctor can review a photo of anything unusual.

A structured photo record is not a diagnosis, cannot exclude skin cancer and does not replace an in-person examination.
