A recent study led by McGill University reveals a troubling trend in Canada: despite increasing rates of skin cancer, Canadians are spending more time in the sun and using less protection. The research, based on survey data from over 77,000 participants, highlights a gap in public health efforts as melanoma cases surge, published in BMJ Public Health.
The study analyzed national survey data collected between 2011 and 2018, representing a weighted sample of 21 million Canadians. Findings showed that 75% of adults spent at least 30 minutes in the sun on summer days off, with nearly half staying out for two hours or more. Most reported inconsistent or no sunscreen use, and one in three experienced a sunburn in the past year.
Young adults were particularly at risk, with higher rates of sunburns, tanning bed use, and lower adoption of protective clothing. Dr. Ivan Litvinov, the study’s senior author and Associate Professor of Dermatology at McGill, expressed concern: “Episodic sunburns, especially in childhood or adolescence, significantly increase the risk of melanoma later in life.” He attributed these behaviors to cultural beauty standards, a sense of invincibility among youth, and potential cost barriers.
Melanoma, the deadliest form of skin cancer, saw a 17% increase in cases in 2024, with approximately 11,000 new diagnoses nationwide. Other skin cancer types are also on the rise.
The study underscores the urgent need for renewed public health campaigns to address sun safety misconceptions, particularly among young adults. As skin cancer rates climb, researchers emphasize the importance of consistent sun protection to curb preventable risks.
