What You Need to Know About the Rise in Skin Cancer
"The back is one very notable example because obviously, we can't see what's going on," says Khan. "The other is between the toes, the scalp, behind the ears, under the breasts, the genital area, and the buttocks." Banwell echoes this, particularly for those with darker skin tones. "Those with darker skin tones should look out for darker spots that bleed, grow, appear darker or lighter, or change in any way," he says. "Even though those with fairer skin are more prone, it does not mean that those with darker skin tones won't be affected."
Old misconceptions, new dangers
"One of the biggest misconceptions is that sunbeds are a 'safer' way to get a 'base tan'. This is not the case whatsoever," says Banwell. "We know that skin cancer is caused by exposure to the Solar Constant — i.e. the combination of ultraviolet radiation (UV-A and UV-B), infrared (IR) and visible light from the sun. Intense exposure via sunbed use also dramatically increases the risk of skin cancer formation (between 30–70%), and thus avoidance of sunbeds is mandatory."
Another common myth? That sunscreen isn't necessary in winter or cloudy weather. "You should be wearing sunscreen throughout the year," Banwell insists. And age isn't a get-out clause. "Skin cancer can affect those at any age," he adds. "Repeated sun exposure without protection can really increase your risk."
How often should you check your skin?
"I think the golden rule," says Khan, "is that anything that is present for two months or more, whether it's just a reddish lesion which doesn't heal, or whether it's a pigmented lesion which is undergoing any change, these are the things that people need to be aware of.' For those with a personal or family history, vigilance is essential. "We need to have our moles checked or check ourselves at least once a month," Khan says.
"Dermatologist visits can be every three to six months, and we can use mole mapping to establish whether lesions are changing," Khan adds. Genetic mutations like CDKN2A may also require screening, he notes, adding that "Once one has had a family history or a melanoma oneself, this is no longer about just prevention. It is a medical necessity."
What's new in detection and treatment?
Artificial intelligence is already transforming early diagnosis. "It has evaluated many thousands of lesions and can now detect melanoma and other cancers with almost the same accuracy as a dermatologist," says Khan. Tools like MoleScope and Reflectance Confocal Microscopy (RCM) allow virtual biopsies and high-resolution skin imaging. "This is a real breakthrough," he adds.
