Skin cancer is the most common cancer type in the Netherlands. One in five people will develop skin cancer, and we expect that the number of diagnoses will only increase. At the Netherlands Cancer Institute, we know what kind of damage the sun can cause, which is why we joined the Zonvenant as a strategic partner: an initiative of the Huidfonds, the Dutch skin foundation. Through this declaration of intent, we will work harder to inform the public, patients, and colleagues of the risks of developing skin cancer through sun exposure.
