WHO Raises Concern, Says Global Cancer Burden Growing, Amidst Mounting Need For Services

Ahead of World Cancer Day, the World Health Organization (WHO) has raised concerns about global cancer burden growing and the increasing need for services.

WHO’s cancer agency, the International Agency for Research on Cancer (IARC), released the latest estimates of the global burden of cancer while WHO also published survey results from 115 countries, showing a majority of countries do not adequately finance priority cancer and palliative care services, as part of universal health coverage (UHC).

The IARC estimates, based on the best sources of data available in countries in 2022, highlight the growing burden of cancer, the disproportionate impact on underserved populations, and the urgent need to address cancer inequities worldwide.

In 2022, there were an estimated 20 million new cancer cases and 9.7 million deaths. The estimated number of people who were alive within 5 years following a cancer diagnosis was 53.5 million. About 1 in 5 people develop cancer in their lifetime, approximately 1 in 9 men and 1 in 12 women die from the disease.

The global WHO survey on UHC and cancer shows that only 39% of participating countries covered the basics of cancer management as part of their financed core health services for all citizens, ‘health benefit packages’ (HBP). Only 28% of participating countries additionally covered care for people who require palliative care, including pain relief in general, and not just linked to cancer.

*Projected cancer burden increase in 2050

Over 35 million new cancer cases are predicted in 2050, a 77% increase from the estimated 20 million cases in 2022. The rapidly growing global cancer burden reflects both population ageing and growth, as well as changes to people’s exposure to risk factors, several of which are associated with socioeconomic development. Tobacco, alcohol and obesity are key factors behind the increasing incidence of cancer, with air pollution still a key driver of environmental risk factors.

In terms of the absolute burden, high HDI countries are expected to experience the greatest absolute increase in incidence, with an additional 4.8 million new cases predicted in 2050 compared with 2022 estimates. Yet the proportional increase in incidence is most striking in low HDI countries (142% increase) and in medium HDI countries (99%). Likewise, cancer mortality in these countries is projected to almost double in 2050.

“The impact of this increase will not be felt evenly across countries of different HDI levels. Those who have the fewest resources to manage their cancer burdens will bear the brunt of the global cancer burden,” says Dr Freddie Bray, Head of the Cancer Surveillance Branch at IARC.

“Despite the progress that has been made in the early detection of cancers and the treatment and care of cancer patients–significant disparities in cancer treatment outcomes exist not only between high and low-income regions of the world, but also within countries. Where someone lives should not determine whether they live.

“Tools exist to enable governments to prioritise cancer care, and to ensure that everyone has access to affordable, quality services. This is not just a resource issue but a matter of political will,” says Dr Cary Adams, head of UICC – Union for International Cancer Control.
