Skin Cancer Risk May Significantly Decrease After Quitting Sunbeds, Experts Say

Individuals who have used sunbeds in their youth may not be destined to develop melanoma, experts have stated, with evidence suggesting that the skin has a capacity to repair itself once excessive ultraviolet (UV) radiation exposure is reduced. The risk of developing melanoma, a deadly form of skin cancer, could fall significantly after three to four years of abstaining from sunbeds and further sunburn, according to Dr. Christopher Rowland Payne, a consultant dermatologist at The London Clinic.

While the risk may never return to that of someone who has never used a sunbed or sunbathed, it can get "pretty close," he explained. This improved outlook applies even to those who used sunbeds for decades or were once frequent sunbathers, provided there is no continued burning.

Melanoma, which claims approximately 2,600 lives annually in the UK, is strongly linked to UV exposure. Studies indicate that individuals who have experienced more than five sunburns in childhood are about 80% more likely to develop melanoma. A single blistering sunburn during childhood or adolescence can potentially more than double this risk. Research also suggests that the dangers of developing the disease later in life can stem from UV exposure at a young age.

Chelsea Tantum, who died from melanoma at age 30, regularly used sunbeds from the age of 15. Her case highlights the severe consequences of prolonged UV exposure. Studies have shown that starting sunbed use before age 35 increases melanoma risk by 87%. A large Norwegian study found that women who began using sunbeds before age 30 had a melanoma risk about one-third higher than those who had never used them, and were diagnosed an average of 2.2 years earlier.

Melanoma UK reports that the risk of melanoma rises by up to 20% for each decade of sunbed use. The charity Melanoma UK states that the risk rises by up to 20 percent for each decade of use. A major analysis published in the British Medical Journal in 2012 found that first using a sunbed before the age of 35 increased the risk of melanoma by 87 percent. A large Norwegian study of 141,000 women found that those who started using sunbeds before the age of 30 had a melanoma risk around a third higher than women who had never used them. They were also diagnosed 2.2 years earlier on average. The BMJ review also found that anyone who had ever used a sunbed was 20 percent more likely to develop melanoma than someone who had never used one. And charity Melanoma UK says the risk rises by up to 20 per cent for each decade of use.

Sunbeds emit UV rays that are significantly stronger than average sunlight, with some studies indicating they can be up to 12 times stronger than natural sunlight and a third more potent than the hottest summer day in Britain. These concentrated rays penetrate the skin, damaging DNA in skin cells and, with repeated use, can cause mutations that lead to cancer. Dr. Rowland Payne emphasized that sunbeds are particularly harmful due to this higher concentration of radiation.

Despite these risks, experts stress that not all UV damage leads to cancer. The skin possesses a remarkable ability to repair itself. However, other forms of skin damage, including non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma, can take longer to develop and may remain linked to past UV exposure for many years. Merkel cell carcinoma, though rare, is also an aggressive cancer linked to excessive UV exposure.

Prevention remains key, with Cancer Research UK stating that the vast majority of skin cancer cases are preventable. Avoiding sunbeds and practicing sun safety are the most effective measures. This includes covering up with clothing, wearing wide-brimmed hats, and using UV-protective sunglasses. Applying sunscreen with an SPF of at least 30 generously and reapplying regularly is also recommended.
