It's very common
Skin cancer is the most common cancer affecting New Zealanders.
Skin cancers are commonly put into two groups - melanoma and non-melanoma skin cancer, with melanoma being the most dangerous.
More than 2,000 melanomas are reported each year in New Zealand. In addition, an estimated 67,000 other skin cancers (such as squamous cell and basal cell carcinomas) are treated.
Melanoma is the most dangerous skin cancer. If left untreated, it can spread rapidly to other parts of the body.
- appear as a new spot
- be an existing spot, freckle or mole that changes colour, size or shape
- sometimes be itchy or bleed
- look different to other spots
- appear anywhere on the body (even on parts that aren’t usually exposed to the sun, such as the soles of your feet or under your toenails)
- be raised ('sticky out') and look shiny in appearance
- appear quickly.
DermNet New Zealand’s website provides more images of melanoma.

Non-melanoma skin cancer
The two common types of non-melanoma skin cancer are:
- basal cell carcinomas (BCC)
- squamous cell carcinomas (SCC).
Basal cell carcinoma
BCCs can appear as a pale red or pearly smooth lump, usually on the face or neck.
Squamous cell carcinoma
SCCs often appear as a raised, crusty, non-healing sore. They are commonly found on the hands, forearms, ears, face or neck. SCCs that are on the lips and ears have a high risk of spreading.
If you are concerned about any spot or lump, get it checked by a doctor as soon as possible.
