Global cancer cases projected to rise 67% by 2050

Global cancer cases are projected to increase by 67% by 2050, reaching an estimated 34.4 million new annual diagnoses. This follows data from the International Agency for Research on Cancer and the American Cancer Society, which recorded approximately 20.6 million new cases and 9.8 million deaths in 2024.

Researchers attribute the rising numbers to population growth and increased life expectancy. Lung cancer remains the most frequently diagnosed cancer and the leading cause of cancer-related deaths, accounting for 2.6 million new cases and 1.9 million deaths in 2024. Breast cancer follows with 2.4 million new cases.

While one in five people is expected to be diagnosed with cancer during their lifetime, experts emphasize that the burden can be mitigated. Key prevention strategies include reducing tobacco use, limiting alcohol consumption, managing weight, increasing physical activity, and preventing cancer-related infections. Improving early detection and access to diagnostic and treatment services are also critical to reducing future mortality rates.
