Tanning beds: A dangerous habit with serious health implications
Heidi Tarr's story is a stark reminder of the dangers of tanning beds. As a teenager, she and her friends indulged in the popular trend of using tanning beds to achieve a celebrity-like glow. Little did they know, this seemingly harmless pursuit could have severe consequences.
Fast forward to her 30s, and Heidi discovered a concerning mole on her back, which turned out to be melanoma, the deadliest form of skin cancer. This experience led her to take action and have over a dozen biopsies to remove more moles. Now, her 15-year-old daughter, Olivia, is curious about the same trending videos on TikTok, showcasing people's tan lines. This sparked an idea in Heidi, leading her to contribute to a groundbreaking study published in the journal Science Advances.
The study reveals a shocking finding: people who use tanning beds are nearly three times more likely to develop skin cancer. It also uncovers the mechanism behind this increased risk. Researchers identified how sunbeds cause DNA mutations in the skin, making users more susceptible to cancer. The World Health Organization's International Agency for Research on Cancer (IARC) confirms that over 80% of the most common melanomas are caused by exposure to ultraviolet radiation, whether from the sun or tanning beds.
Pedram Gerami, a dermatologist and researcher at Northwestern University, noticed an unusually high number of younger women with multiple melanomas. His team compared medical records of 3,000 tanning bed users with those of similar individuals who didn't use tanning beds. The results were alarming: 5% of tanning bed users had melanoma, compared to 2% in the other group. After adjusting for various factors, researchers estimated that tanning bed users were nearly 2.9 times more at risk of melanoma.
The study also focused on the DNA damage caused by tanning beds, as this damage can accumulate and lead to cancer. Researchers analyzed 182 biopsies, including one from Heidi Tarr, and discovered that tanning bed users' melanocytes had nearly twice as many mutations. Bishal Tandukar, a study co-author, emphasized the severity of the situation, stating that tanning bed users in their 30s and 40s had more mutations than people in their 70s and 80s in the general population.
The implications are clear: melanoma is a deadly disease, claiming almost 60,000 lives worldwide in 2022, according to the IARC. Tanning beds are classified as having the highest level of cancer risk, comparable to smoking and asbestos. Several countries, like Australia and Brazil, have banned tanning beds entirely, while others, including the UK and France, prohibit their use for minors under 18. In the US, the regulations vary by state, but Gerami strongly advocates for a ban on tanning beds for minors.
Heidi Tarr's message is a call to action: 'For those who might be thinking about using a tanning bed - or for parents who might be thinking of letting their teenagers use a tanning bed - I just would extremely recommend: don't use them.' She emphasizes the importance of regular skin inspections and encourages people to consult dermatologists for proper checks. For those craving a tanned look, she suggests alternative methods like lotion or spray tans.
