So there are a number of risk factors for skin cancer. The first is if you have very pale skin. So if you're very fair-skinned, you've got blonde hair, you've got blue eyes, that's the first risk factor. The second thing is if there is a family history of melanoma. So about 10% of melanomas run in families. If you've got a first-degree relative that has suffered with that, you're at a slightly higher risk. The third thing is if you have a large number of moles. So if you've got over 100 moles on your body and a lot of them look quite different to each other, something called atypical mole syndrome, that can put you at more risk. The fourth thing is having multiple sunburns, particularly before the age of 18. So four or five sunburns below the age of 18 can double your lifetime risk of developing melanoma. It's also a good idea not to use sunbeds, because using sunbeds can also give you high doses of ultraviolet light that, again, can promote development of skin cancers further down the line. If you enjoy a lot of outdoor hobbies and you've had a lot of sunburns, that puts you more at risk as well. So when you see a dermatologist, they will make an assessment of all these risk factors.
