Why So Many Canadians Still Ignore Life-Saving Sunscreen Habits

Skin cancer remains one of the most common yet preventable cancers worldwide. Despite widespread access to sunscreen, many Canadians fail to use it correctly—or at all. Experts warn that improper protection against UV rays leads to thousands of avoidable cases each year.

UV exposure from the sun, tanning beds, or UV lamps causes 80 to 90 percent of skin cancers. These include melanomas, which rank among the top 10 most diagnosed cancers in Canada. In 2025 alone, an estimated 10,800 Canadians received a melanoma diagnosis. Tragically, three to four people die from the disease daily in the country.

Proper sunscreen use could drastically reduce these numbers. Adults need about an ounce—roughly the size of a shot glass—for full-body coverage. Reapplication every two hours is essential, or more frequently when swimming or sweating. Yet many skip these steps, leaving skin unprotected. A tan, often seen as healthy, actually signals DNA damage from UV rays. In Germany, 27,430 people were diagnosed with malignant melanoma in 2023, showing the global scale of the issue. With consistent sun safety, experts say most cases could be prevented.

Skin cancer rates remain high, but prevention is straightforward. Correct sunscreen use, avoiding tanning beds, and seeking shade can cut risks significantly. Public health campaigns continue to stress these measures, aiming to lower diagnoses and save lives.
