ARE YOU AT RISK?

What puts me at risk of skin cancer?

Everyone, regardless of skin colour, is potentially at risk for skin cancer. Anyone who spends time outdoors is at risk — not just those who sunbathe. But some people are at a higher risk for skin cancer than others, either because of their skin typeor their behaviour in the sun.

A number of things can put you at risk of developing skin cancer. But there’s good news. You can always do something to reduce your risk.

The risk factors are:

your skin type   •   ultraviolet radiation   •   ozone depletion   •   tanning   •   sunburn

Does my skin put me at greater risk?

Human skin varies greatly in response to UV exposure. In general, there is a more damaging response in people who have very fair skin, who cannot or have difficulty tanning after sun exposure (see table below) In general, people with skin types I & II are most vulnerable to the effects of UVR, both short-term effects such as sun burning and long-term effects such as skin cancer and ageing.

Skin Type Unexposed Skin Colours UVR Sensitivity Sunburn History Tanning Ability
I White Extremely Sensitive Always burns on minimal exposure Never tans
II White Very Sensitive Burns very readily Tans slowly and with difficulty, freckles common
III White Moderately Sensitive May burn on regular sun exposure with no protection Tans relatively slowly
IV Light Brown Relatively Tolerant Burns rarely Tans rapidly on minimal sun exposure
V Brown Very Variable Despite pigmentation, may burn very easily on sun exposure Difficult to detect on heavily pigmented skin
VI Black Relatively insensitive Rarely burns (NB sunburn is difficult to detect on heavily pigmented skin) Difficult to detect on heavily pigmented skin

Two thirds of Irish people have types I or II skin so take extra care if you have:

  • pale or freckled skin that burns easily or doesn’t tan;
  • naturally red or fair hair;
  • blue, green or grey eyes;
  • 50 or more moles;

You should also take extra care (even if you are not skin type I or II) if you:

  • have a history of sunburn;
  • have a personal or family history of skin cancer; or
  • spend a lot of time working or playing outdoors.
