Melanoma
Last update
3097 new cases of melanoma have been registered in Norway in 2025. Melanoma of the skin is the most serious form of skin cancer and is among the forms of cancer that are increasing the most in Norway.
About melanoma
Melanoma usually occurs in the skin and develops from the pigment-forming cells in the skin. In rare cases, melanoma can occur in the eye and mucous membranes (vagina, throat, intestine). Melanoma is the skin cancer that takes the most lives. Below we provide figures and information for melanoma of the skin.
The number of melanoma cases globally has increased sharply in populations with fair skin type, and the incidence in Norway is among the highest in the world.

Risk factors
The most important causative factor for melanoma of the skin is ultraviolet (UV) radiation from the sun and tanning beds. The significant increase in incidence over the past few decades is likely due to changes in sun habits and increased UV exposure, particularly among men over the age of 50.
Those at the highest risk are individuals with fair skin and blond or red hair, as well as those with many or large moles. In addition, other factors (e.g., overweight, use of certain medications, chemicals) may also play a role.
Some families appear to be genetically predisposed to skin cancer. They may request genetic testing and special follow-up.
You can find more about risk factors in the overview from WCRF.
There are several studies that have looked into the risk of melanoma. An overview of factors identified as carcinogenic based on International Agency for Research on Cancer monographs:
