Cancer Cases To Surge To 35 Million By 2050: WHO Report

A recent report by the World Health Organisation (WHO) has warned that cancer is poised to become one of the world's biggest public health challenges. The Global Status Report on Cancer 2026 estimates that annual cancer cases will surge from 20.6 million in 2024 to 35 million by 2050.

The report highlights that one in every five people worldwide will develop cancer during their lifetime, while nearly 92% of the global population will be affected by the disease either directly or through a family member's diagnosis. Asia currently bears the largest burden, accounting for 53% of all new cancer cases globally.

According to the report, nearly 10 million people died from cancer in 2024, making it the second leading cause of death globally after cardiovascular diseases. Cancer now contributes to 16.5% of all global deaths, and more than 4.8 million deaths occur among adults aged 30 to 69 years.

The WHO attributes the rising burden of cancer to population growth, ageing, and increasing exposure to risk factors such as tobacco use, obesity, alcohol consumption, and physical inactivity. The agency estimates that global cancer incidence will increase by 66.7% by 2050, with the biggest rise expected in low-income countries and lower-middle-income countries.

The report also reveals stark inequalities in cancer outcomes, with five-year survival rates for several cancers exceeding 85% in high-income countries, but dropping to below 45% in low-income countries. Access to early diagnosis, treatment, and specialised care remains limited in low-income countries.

Breast cancer remains the most common cancer among women, with 2.4 million new cases in 2024, while lung cancer is the leading cancer among men, with 1.6 million new cases and 1.3 million deaths. Colorectal cancer continues to be the third most common cancer worldwide.

The economic consequences of cancer are equally alarming, with the cumulative global economic cost of cancer projected to exceed US$33.2 trillion (Rs 2,85,520 lakh crore) between 2020 and 2050. This will impose a heavy burden on health systems, economies, and households.

Despite some encouraging progress, including a decline in global tobacco use and an increase in HPV vaccination coverage, the report notes that only 28% of countries currently provide a minimum package of cancer services under universal health coverage. This leaves millions without access to essential care.

In conclusion, the WHO report highlights the urgent need for stronger health systems and equitable access to cancer care. The projected surge in cancer cases and the significant economic burden it will impose underscore the importance of addressing this major public health challenge.

The report's findings have significant implications for India, which has a large and growing population. The country needs to strengthen its health systems and improve access to cancer care to address the rising burden of cancer. This will require increased investment in healthcare infrastructure, as well as efforts to reduce risk factors and improve early diagnosis and treatment.

Overall, the WHO report serves as a wake-up call for governments, healthcare systems, and individuals to take action to address the growing burden of cancer. It is essential to work together to reduce the incidence of cancer, improve access to care, and mitigate the economic consequences of this devastating disease.

The report's warning that cancer will become one of the world's biggest public health challenges is a stark reminder of the need for urgent action. It is crucial that we take steps to address the rising burden of cancer, both globally and in India, to reduce the suffering and economic burden it imposes on individuals, families, and societies.

In the coming years, it is essential that we prioritize cancer prevention and treatment, improve access to care, and reduce the economic consequences of the disease. This will require a concerted effort from governments, healthcare systems, and individuals to address the growing burden of cancer and mitigate its impact on global health.
