Cancer is claiming more than 26,000 lives every day worldwide, with the World Health Organization (WHO) warning that millions of those deaths could be prevented if countries invested more in early detection, affordable treatment and stronger healthcare systems.
According to the WHO and the International Agency for Research on Cancer (IARC), cancer causes nearly 10 million deaths every year, making it the world’s second-leading cause of death. More than 20.6 million new cases are diagnosed annually, and without urgent intervention, the figure is projected to rise to almost 35 million by 2050.
While scientific advances have improved survival rates in many parts of the world, the WHO says the greatest challenge is no longer simply fighting cancer itself but ensuring that life-saving care is available regardless of where people live or how much they earn.
The report reveals that the global cancer burden is being fuelled by preventable risk factors such as tobacco use, alcohol consumption, unhealthy diets, obesity and physical inactivity, which account for about 40 per cent of cancer cases. In many low/middle income countries, chronic infections including the Human Papillomavirus (HPV) and Hepatitis B/C viruses, remain responsible for roughly 30% of cases, while ageing populations continue to drive rising diagnoses worldwide.
Millions of patients see cancer diagnosis as emotional trauma; thus, afar from the medical statistics, there lies a growing human crisis, such as the loss of income, difficult choices to be made between treatment and basic family needs, etc. Across many developing countries, families often exhaust their savings, borrow, sell valuable assets or cut-down basic/sundry expenditure to finance treatment. The report highlights a stark survival divide, between the wealthy and poorer nations.
In Europe and North America, although about one in four people is expected to develop cancer during their lifetime, only around one in about 12 dies from the disease, reflecting stronger screening programmes, earlier diagnosis and better access to modern treatment.
In contrast, many countries across sub-Saharan Africa, experience the struggle for treatment with shortages of oncology specialists, diagnostic equipment, radiotherapy facilities and affordable medicines. Delayed diagnosis and limited treatment options, significantly reduce survival chances, particularly for low-income households. Breast cancer cases comparison between the social-classes, illustrates the difference most clearly. Nearly 90% of women diagnosed in high-income countries, survive for at least five years after diagnosis, compared with just over 40% in low-income countries, where access to timely diagnosis and comprehensive treatment remains limited.
