Belgium Faces Surge in Cancer Diagnoses: 44 More Cases Per Day by 2035
Belgium is bracing for a significant rise in cancer diagnoses over the next decade, with projections indicating an additional 44 new cases detected every day by 2035. According to the latest report from the Belgian Cancer Registry Foundation, the country could see a 21% increase in annual cancer diagnoses, jumping from 77,344 cases in 2023 to approximately 93,330 by 2035. The findings, released on April 27, 2026, highlight the urgent need for strengthened prevention efforts and healthcare system preparedness.
Dr. Helena Fischer, Editor of Health at World Today Journal, explains the implications: “This projected rise isn’t just a statistical concern—it reflects real pressure on Belgium’s healthcare infrastructure. With an aging population and increasing life expectancy, the country must act now to mitigate the impact on patients, families, and medical resources.” The report underscores that while the overall risk of developing cancer is expected to rise only modestly—by about 3%—the sheer growth in the number of older adults will drive the bulk of the increase.
The surge in diagnoses will not affect all demographics equally. Men are projected to see a sharper rise (24%) compared to women (16%), with the total number of cases climbing from 42,140 in 2023 to 52,350 in 2035 for men, and from 35,204 to 41,000 for women. These disparities reflect both demographic trends and variations in cancer risk factors across genders.
Why Are Cancer Diagnoses Rising?
The Belgian Cancer Registry Foundation attributes the projected increase to three key factors: population growth, aging, and a slight uptick in cancer risk. “The primary driver is demographic,” says Julie Francart, Deputy Director of the Foundation. “Belgium’s population is both growing and aging, and older adults are more likely to develop cancer. The actual risk of cancer per individual is rising only marginally—by about 3%—but the number of people in high-risk age groups is expanding rapidly.”
This distinction is critical. While the overall incidence rate (cases per 100,000 people) is expected to remain relatively stable, the absolute number of diagnoses will climb due to the larger pool of older adults. For example, the proportion of Belgians aged 65 and over is projected to grow from 20% in 2023 to nearly 25% by 2035, according to Statbel, Belgium’s official statistics agency. This shift alone accounts for a substantial portion of the anticipated rise in cancer cases.
Still, not all cancers will see equal growth. The report highlights stark differences in projected increases by cancer type. Some of the steepest rises are expected in:
- Melanoma (skin cancer): +63%
- Liver cancer: +53%
- Pancreatic cancer: +49%
In contrast, cancers of the stomach and ovary are among the few expected to see a decline in diagnoses. The Foundation notes that these variations reflect both changes in risk factors (such as UV exposure for melanoma) and improvements in early detection and treatment for certain cancers.
The Most Common Cancers: What to Expect
The report confirms that the three most common cancers in Belgium—prostate, breast, and lung—will retain their top positions in 2035, though their share of total cases may shift slightly. Together, prostate and breast cancers are projected to account for 30% of all invasive tumors in men and women, respectively. Lung cancer and cancers of the hematolymphoid system (such as lymphomas and leukemias) will follow, representing 12.2% and 10.8% of total cases.
“These projections aren’t just numbers—they represent real people and real challenges,” says Francart. “For instance, lung cancer remains a leading cause of cancer death, and its prevalence is closely tied to smoking rates. While Belgium has made progress in tobacco control, we still see high rates of smoking among certain groups, particularly younger adults and those in lower socioeconomic brackets.”
The rise in melanoma cases is particularly alarming, given its strong link to UV exposure. Belgium has seen a steady increase in melanoma diagnoses over the past two decades, driven in part by changing behaviors, such as increased apply of tanning beds and more frequent sun exposure during holidays. Public health campaigns have sought to raise awareness about sun protection, but the report suggests these efforts must be intensified to curb the projected rise.
Prevention: The Best Tool Against Rising Cases
While the projections paint a sobering picture, experts emphasize that many cancers are preventable. “About 40% of cancers are linked to modifiable risk factors, such as smoking, alcohol consumption, poor diet, and lack of physical activity,” notes the World Health Organization (WHO). In Belgium, public health authorities have long prioritized prevention, but the report calls for renewed efforts to address gaps in awareness and access to screening programs.
Key prevention strategies highlighted in the report include:
- Tobacco control: Smoking remains the leading cause of preventable cancer in Belgium. While smoking rates have declined, about 18% of adults still smoke daily, according to Sciensano, Belgium’s public health institute. Strengthening smoke-free policies and increasing access to cessation programs could help reduce lung cancer and other smoking-related cancers.
- Sun protection: With melanoma cases projected to rise sharply, the report urges greater emphasis on UV protection, particularly among children and outdoor workers. Schools and workplaces could play a key role in promoting sun-safe behaviors, such as wearing protective clothing and using sunscreen.
- Screening programs: Belgium has well-established screening programs for breast, cervical, and colorectal cancers, but participation rates vary. The report recommends targeted outreach to underserved communities, including low-income groups and immigrants, to ensure equitable access to early detection.
- Vaccination: The human papillomavirus (HPV) vaccine, which protects against several cancers, including cervical cancer, is offered free to adolescents in Belgium. However, uptake has been uneven, with some regions reporting lower vaccination rates. The report calls for efforts to improve vaccine coverage, particularly among boys, who are also at risk for HPV-related cancers.
“Prevention isn’t just about avoiding risk factors—it’s also about early detection,” says Francart. “For cancers like breast and colorectal, screening can catch tumors at an early stage, when treatment is most effective. Expanding access to these programs and ensuring they reach all segments of the population is critical.”
Healthcare System Under Pressure
The projected rise in cancer diagnoses will place additional strain on Belgium’s healthcare system, which is already grappling with workforce shortages and rising costs. Oncologists warn that without proactive measures, the increase in cases could lead to longer wait times for diagnosis and treatment, as well as greater pressure on hospitals and specialist clinics.
“Belgium has a strong healthcare system, but it’s not immune to the challenges posed by an aging population,” says Dr. Fischer. “Hospitals and cancer centers will need to expand capacity, invest in new technologies, and ensure that staff are trained to handle the growing number of patients. This includes not just oncologists and surgeons, but also nurses, radiologists, and support staff who play a critical role in cancer care.”
The report also highlights the need for greater investment in palliative care and survivorship programs. As more people live longer with cancer, the demand for supportive services—such as pain management, psychological counseling, and rehabilitation—will grow. “Cancer isn’t just a medical issue. it’s a social and economic one,” says Francart. “We need to ensure that patients and their families have access to the resources they need to cope with the physical, emotional, and financial burdens of the disease.”
What’s Next for Belgium?
The Belgian Cancer Registry Foundation’s projections serve as a call to action for policymakers, healthcare providers, and the public. While the rise in cancer diagnoses is largely driven by demographic trends, the report makes clear that proactive measures can mitigate its impact. Key steps include:
- Strengthening prevention campaigns: Targeted efforts to reduce smoking, promote sun safety, and encourage healthy lifestyles could help curb the rise in preventable cancers.
- Expanding screening programs: Ensuring equitable access to breast, cervical, and colorectal cancer screening could improve early detection and outcomes.
- Investing in healthcare infrastructure: Hospitals and cancer centers will need to expand capacity to accommodate the growing number of patients, including hiring more staff and adopting new technologies.
- Supporting research: Continued investment in cancer research could lead to new treatments, improved diagnostics, and a better understanding of risk factors.
For individuals, the report underscores the importance of staying informed about cancer risks and taking proactive steps to reduce them. “Cancer prevention isn’t just the responsibility of governments and healthcare providers—it starts with each of us,” says Dr. Fischer. “Simple actions, like quitting smoking, wearing sunscreen, and getting regular screenings, can make a real difference in reducing your risk.”
