Lancet Study Warns of Rising Global Cancer Burden
A recent study published in The Lancet warns that cancer deaths worldwide are expected to rise by nearly 75% by 2050, reaching 18.6 million, while new cancer cases could increase 61% to 30.5 million. The surge is largely driven by economic growth and an ageing global population, with low- and middle-income countries facing the sharpest rise.
Since 1990, global cancer deaths have already increased 74% to 10.4 million, and new cases more than doubled to 18.5 million in 2023. Countries with limited healthcare resources are experiencing the fastest growth in cancer cases, highlighting disparities in prevention and treatment access.
India is projected to see one of the steepest increases, with cancer rates rising 26.4% between 1990 and 2023, among the highest worldwide. In contrast, China experienced a 18.5% decline in cancer rates over the same period. Experts warn that unless urgent action is taken, low-resource countries like India will face a growing healthcare burden.
The study identifies preventable risk factors contributing to over 40% of global cancer deaths. Key risks include tobacco use, unhealthy diets, high blood sugar, and other lifestyle-related factors, emphasizing the potential for prevention through policy and behavioral interventions.
Dr Lisa Force, lead author from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, highlighted the lack of prioritization and funding for cancer control globally. “Despite the clear need for action, cancer control policies remain underfunded in many regions,” she said.
The Global Burden of Disease (GBD) study, which analyzed data from 204 countries and territories, also revealed disparities in cancer outcomes. While overall global death rates fell 24% between 1990 and 2023, low-income countries saw 24% more new cases, and lower-middle-income countries experienced a 29% rise, reflecting unequal progress in cancer prevention and treatment.
Researchers emphasize that cancer will remain a major contributor to global disease burden, and the projected increases over the coming decades will disproportionately affect countries with limited healthcare resources. The study calls for stronger global initiatives to tackle preventable risks, improve early detection, and strengthen healthcare systems to manage the looming crisis.
