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.

Milia are tiny white or yellowish bumps just beneath the skin’s surface — little cysts of trapped keratin, most common around the eyes and cheeks. They are completely harmless. The reason to know them is that a persistent, single white or pearly bump can occasionally be an early basal cell carcinoma, which is worth a doctor’s eye.

What milia look like

Milia vs an early BCC: how to tell

FeatureMilia (harmless)Early BCC — worth checking
ColourUniform white to pale yellowPearly or pink; may have tiny visible blood vessels
Size & numberTiny (1–2 mm), often several togetherUsually a single spot that slowly enlarges
Over timeStable for months or yearsGrows, bleeds, crusts, or will not heal
SurfaceSmooth, dome-shaped, grain-likeShiny, or a central dip that scabs and returns

When a “white bump” is worth checking

Have a bump looked at — rather than assuming it is milia — if it is single and growing, pearly with tiny visible blood vessels, bleeds or crusts, or will not heal. Those are features that can point to an early BCC rather than a harmless milium.

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.
