Why Skin Cancer Rates Keep Rising Despite Easy Prevention

Skin cancer remains one of the most common and preventable cancers worldwide. In Canada, melanoma ranks among the top 10 most diagnosed cancer types, with thousands of cases reported each year. Despite this, many people still fail to use sunscreen properly—or at all.

In 2023, Germany recorded around 27,430 cases of malignant melanoma, highlighting the widespread impact of skin cancer. While exact figures for Canada in 2025 are not yet available, estimates suggest over 10,800 Canadians will receive a melanoma diagnosis that year. Globally, one in three cancers diagnosed is skin cancer, with 80 to 90 per cent linked to UV exposure from the sun or artificial sources like tanning beds.

A tan may seem harmless, but it actually signals DNA damage caused by UV rays. To reduce risk, experts recommend applying about an ounce of sunscreen—roughly the size of a shot glass—for full-body protection. Reapplication every two hours, or more often when swimming or sweating, is also crucial. Yet many Canadians still neglect these steps, even though proper sun protection could prevent most cases.

Tragically, melanoma claims the lives of three to four Canadians daily. The disease is largely preventable, making awareness and correct sunscreen use more important than ever.

Skin cancer continues to affect thousands, but simple precautions can drastically lower the risk. Proper sunscreen application and avoiding excessive UV exposure remain key to reducing diagnoses and deaths. With melanoma still a leading cancer in Canada, public education on sun safety could save lives.
