Skin cancer cases surge as Canadians ignore sunscreen warnings

Skin cancer remains one of the most common and preventable forms of cancer worldwide. In Canada alone, melanoma is projected to affect 10,800 people in 2025, with many cases linked to avoidable UV exposure. Despite widespread awareness, proper sunscreen use is still overlooked by many.

Experts highlight that one in three cancers diagnosed globally is skin-related, with 80 to 90 percent caused by UV rays. These rays come from natural sunlight as well as artificial sources like tanning beds and UV lamps. A tan, often seen as desirable, is actually a sign of DNA damage to skin cells.

To protect against harm, sunscreen must be applied correctly. Adults need about an ounce—roughly the size of a shot glass—for full-body coverage. Reapplication is crucial every two hours, or more frequently if swimming or sweating. Yet many Canadians either skip sunscreen entirely or use it incorrectly. Melanoma ranks among Canada's top 10 most diagnosed cancers. Tragically, three to four people die from it daily, though most cases could be prevented with proper sun safety measures.

The projected 10,800 melanoma diagnoses in 2025 underscore the ongoing risk of UV exposure. Simple steps—like consistent sunscreen use and avoiding tanning beds—could drastically reduce cases. Safer alternatives, such as bronzer or spray tans, are recommended to prevent long-term skin damage.
