The World Health Organisation (WHO) has stated that almost the entire global population will experience the impact of cancer by the year 2050. This assertion is backed by the WHO Global Status Report on Cancer 2026, which was released on July 8. The report, developed in collaboration with the International Agency for Research on Cancer (IARC), projects a notable rise in annual cases, estimating that the number of new cancer cases will increase from 20.6 million to approximately 35 million over the next 25 years, marking an increase of 66.7 per cent.

Current statistics indicate that cancer is responsible for nearly 10 million deaths each year, averaging over 26,000 fatalities daily. It is positioned as the second leading cause of death globally, following cardiovascular diseases. The report highlights that, beyond the direct health implications, cancer is placing an escalating emotional, social, and financial burden on patients and their families.

According to the report, an alarming 92 per cent of individuals worldwide are expected to be affected by cancer in some form during their lifetime, whether through a personal diagnosis or by caring for others diagnosed with the disease. WHO Director-General Dr Tedros Adhanom Ghebreyesus stated that the existence of disparities in cancer care and outcomes is not unavoidable and can be mitigated through proactive global initiatives.

Preventable Factors and Urgent Prevention Measures

WHO’s report indicates that nearly four in ten cancer cases are associated with preventable risk factors such as tobacco use, excessive alcohol consumption, unhealthy diets, physical inactivity, and infections like human papillomavirus (HPV) and hepatitis. Dr Elisabete Weiderpass, Director of IARC, noted that although some nations have successfully reduced cancer incidence through prevention-focused policies, much progress remains necessary. She stressed that the evolving cancer landscape, driven by rising obesity rates and environmental issues, must remain a priority on the political agenda.

The report brings to light deeply rooted disparities in cancer survival rates between high-income and low-income nations. For instance, while 87 per cent of women in high-income countries diagnosed with breast cancer survive for at least five years, this statistic drops to approximately 42 per cent in low-income countries. This is primarily due to delays in diagnosis and inadequate access to effective treatment options.

Additionally, less than one-third of countries incorporate comprehensive cancer care in their universal health coverage plans, leaving millions without essential services. The availability of critical cancer medications also varies significantly, with low- and lower-middle-income countries having access to only 9 to 54 per cent of essential treatments, in stark contrast to 68 to 94 per cent in high-income nations.

Asia Faces Significant Cancer Burden

Asia is reported to bear the highest cancer burden, accounting for over half of global cancer cases (50.7 per cent) and deaths (56.5 per cent) as of 2024, primarily due to its large population. Lung cancer remains the leading cause of cancer-related deaths worldwide, with men experiencing high rates of lung, prostate, and colorectal cancers, while women predominantly face breast, lung, and colorectal cases.

The impact of cancer extends beyond mere health statistics. WHO’s comprehensive survey indicated that the repercussions of the disease reach far into financial sustainability and mental health. At least 45 per cent of cancer patients reported facing financial difficulties, while over half experienced mental health challenges. Caregivers also reported significant strains due to unpaid responsibilities and social isolation, illustrating the all-encompassing effects of the disease on a person’s life.

While some progress has been made since 2010—such as a 27 per cent decline in tobacco use—WHO stresses that these advancements are insufficient to manage the growing cancer burden. The report calls upon governments to concentrate on enhancing cancer prevention efforts, broadening access to screenings and treatments via universal health coverage, investing in healthcare professionals, and ensuring that essential medicines remain affordable and accessible to all.
