New estimates from the World Health Organization (WHO) predict a substantial global Cancer Surge, reaching a staggering 35 million cases in 2050. This marks a significant 77% increase from the 20 million cases diagnosed in 2022, as revealed by data released on Friday by WHO’s International Agency for Research on Cancer. The report comprehensively covers 185 countries and 36 different forms of cancer, shedding light on the growing impact of this pervasive disease.
Current Cancer Landscape and Inequities
Lung cancer emerged as the most prevalent form worldwide in 2022, contributing to 2.5 million cases, or 12.4% of the total diagnoses. The report identified female breast, colorectal, prostate, and stomach cancers as the subsequent most common forms. Alarmingly, lung cancer also accounted for the highest number of cancer-related deaths, causing 1.8 million fatalities, nearly 19% of the total.
Additionally, the report highlighted significant disparities in cancer burden across developed nations, emphasizing the impact of the Human Development Index (HDI). In countries with high HDI, breast cancer diagnosis rates are higher, but the death rates are comparatively lower than in low-HDI countries, where late diagnosis and limited access to treatments contribute to higher mortality rates.
Furthermore, the study exposed inequities in cancer services such as radiation and stem cell transplants, indicating a global struggle to provide adequate care. Dr. Bente Mikkelsen, director of WHO’s Department of Noncommunicable Diseases, expressed concern over the lack of financial protection for cancer care, especially in lower-income countries.
Driving Factors for Cancer Surge and National Initiatives
Several factors were identified as driving the expected Cancer Surge rates globally, including obesity, tobacco use, alcohol consumption, and environmental factors such as air pollution. While the United States has witnessed a decline in cancer-related deaths, certain forms of cancer are on the rise, posing new challenges. Racial disparities persist, with people of color facing higher risks, and the incidence of cancer in younger populations is increasing.
President Joe Biden’s commitment to the cancer fight was emphasized, with the Cancer Moonshot effort aimed at halving US cancer deaths in the next 25 years. The report also underscored the need for major investments to address global inequities in cancer outcomes, stressing that where someone lives should not determine whether they live. Dr. Cary Adams, head of the Union for International Cancer Control, highlighted the existing tools and called for political will to prioritize cancer care and ensure universal access to affordable, quality services.
