Global Cancer Burden Projected to Surge, Warns WHO

By The Inspirer.

As the world marks World Cancer Day on Sunday, February 4, the International Agency for Research on Cancer (IARC), the cancer agency of the World Health Organization (WHO), unveiled concerning projections for the global cancer burden.

By 2050, cancer cases are anticipated to surge by 77%, totaling over 35 million new cases worldwide. This marks a significant increase from the estimated 20 million cases reported in 2022.

The rising cancer burden is attributed to factors such as population aging, growth, and changing exposure to risk factors linked to socioeconomic development.

Tobacco, alcohol, and obesity are identified as key contributors, with air pollution also playing a pivotal role in environmental risk factors.

A survey conducted by WHO across 115 countries revealed that most nations lack adequate funding for priority cancer and palliative care services under universal health coverage (UHC).

The IARC’s estimates for 2022 underline the urgency of addressing cancer inequities globally. In that year alone, an estimated 20 million new cancer cases and 9.7 million deaths were reported. The data also indicates that approximately one in five people develop cancer in their lifetime, with one in nine men and one in twelve women succumbing to the disease.

The survey further highlights that only 39% of participating countries cover the basics of cancer management in their financed core health services for all citizens. Additionally, just 28% of countries extend coverage to care for those requiring palliative care, emphasizing the need for improved financial backing for cancer services.

The Global Cancer Observatory data for 2022 reveals that lung, breast, and colorectal cancers collectively accounted for two-thirds of new cases and deaths worldwide. Lung cancer topped the list, with 2.5 million new cases, followed by female breast cancer and colorectal cancer. Lung cancer also led in cancer-related deaths, causing 1.8 million fatalities, followed by colorectal, liver, breast, and stomach cancers.

The estimates demonstrate significant disparities in cancer burdens based on human development. Breast cancer, for instance, presents stark contrasts between high and low Human Development Index (HDI) countries, highlighting the need for focused efforts to address global inequities in cancer outcomes.

Looking ahead to 2050, high HDI countries are expected to witness the greatest absolute increase in cancer incidence, with an additional 4.8 million new cases. However, the proportional increase is most notable in low and medium HDI countries, indicating the unequal distribution of the global cancer burden.

Despite advancements in cancer detection and treatment, disparities persist. The WHO emphasizes the urgency of political will and increased investments to ensure that everyone, regardless of their location or income, has access to affordable and quality cancer care.
