The number of cancer diagnoses in the Netherlands is expected to rise over the next twenty years. New calculations from the Netherlands Comprehensive Cancer Centre (IKNL) predict nearly 170,000 new cases annually by 2045, up from approximately 136,000 currently. This increase is largely attributed to the aging population in the Netherlands, as cancer is more prevalent in older individuals; by 2045, around 20 percent of the population will be 70 or older. However, the IKNL emphasizes that many diagnoses are preventable through focused prevention efforts. Factors such as smoking, alcohol consumption, obesity, lack of exercise, and UV exposure significantly increase cancer risk, though decreased smoking among men has already lowered lung cancer rates. While stomach cancer diagnoses are expected to continue declining, skin cancer is projected to become the most common form of cancer in the Netherlands by 2045 for both men and women. Currently, prostate cancer is most common in men, while breast cancer is most common in women.
