Can you still save your skin from cancer and premature ageing after all that sun exposure?

Pick your favourite cliche: Do as I say, not as I do; an ounce of slotxo prevention is worth a pound of cure; better safe than sorry; forewarned is forearmed.

Mea culpa. All the above relate to my failure to follow the well-established health advice about sun exposure that I’ve offered repeatedly to my readers: Routinely protect your skin from the cancer-causing and ageing effects of the sun’s ultraviolet rays.

For decades, I’ve failed to practise what I preached (okay to wince) and am now paying for my negligence with unsightly splotches, bumps and bruises and at least one cancerous lesion on my sun-damaged skin. My litany of excuses has included: Hats mess up my hair, long sleeves and pants are too hot, and exercising while coated with sunscreen is suffocating.

Vowing to do better, I dutifully purchase the latest dermatology-recommended sunscreen that, alas, remains unopened on a bathroom shelf. I hereby pledge to do better this year, albeit late in the game.

A new report from a dermatology team at Kaiser Permanente health care centres in California has prompted me to reform. The team, headed by the epidemiologist Lisa Herrinton in Oakland, followed nearly half a million patients seen at the centres for up to 10 years. Half had already developed one or more actinic keratosis, a precancerous rough, scaly skin lesion caused by years of unprotected sun exposure.

As you might expect, these lesions most often form on the face, ears, back of the hands, forearms, scalp and neck and are – or should be – routinely removed when found by dermatologists to prevent progression to cancer. The lesions are markers of sun damage and can serve as an early warning system for people at risk of developing cancer somewhere on sun-exposed skin.

While the hazard is greatest for people with light skin, having a dark complexion is not a free pass. Tanning, not just burning, is a form of sun damage.
