Melanoma Risk Factors

The first thing to understand about the risk of melanoma is that anyone can develop a this type of skin cancer

No age group or racial group is totally immune to the effects of UV radiation from the sun and no group is genetically free from the risk of developing malignant skin cancer. Less than 1% of cases of melanoma are found amongst the Maori population in New Zealand but those cases tend to be detected at a later stage and are less likely to be successfully treated.

There are several groups that are more at risk than other groups, but the key message is that you should always be aware of your skin and take action by seeing a doctor if you or your loved ones notice any changes in their moles or develop new moles or marks on the skin.

Melanoma risk factors

Ultra Violet (UV) Light

Ultra Violet (UV) light from the sun causes more than 90% of all cases of melanoma. Here in New Zealand we are particularly at risk because of the hole in the ozone layer that reduces the natural protection afforded to other parts of the world.

Sunburn

If you have had severe sunburn during your early life, you are more at risk of developing melanoma as an adult (but you can still develop melanoma even if you were never sun-burnt as a child).

Sunbeds

Using sunbeds is associated with a greater risk of developing melanoma.

Moles

If you have lots of moles on your body (more than 50-100) you are more at risk of developing melanoma.

Fair skin

If you have fair skin and burn easily you are more at risk.

Family history

A family history of melanoma can mean you are more at risk.

Previous melanoma

If you have already had one melanoma, you are more likely to develop more.

Previous skin cancer

If you have already had any type of skin cancer, you are more likely to develop melanoma.

Age

Most cases of melanoma are identified in people aged over 50 but that could be due to greater diligence and awareness in younger generations of the need to protect themselves against the sun. Some 30% of cases still occur in people under the age of 35.

Ethnicity

Whatever your age or ethnic origin, take steps to protect your skin and be aware of any changes in your skin. Always seek the advice of a doctor if you notice any changes or are worried.
