World Cancer Day is marked annually on 4 February to raise awareness about cancer and to encourage action aimed at prevention, early detection, treatment and care. The day was established in 2000 at the World Summit Against Cancer for the New Millennium in Paris and has since been led by the Union for International Cancer Control, uniting communities across the globe in the fight against the disease.
The aim of World Cancer Day is to promote research, improve education and mobilise individuals, organisations and governments to make meaningful progress in addressing cancer. Supporters are working together to reimagine a world where everyone has access to cancer prevention, treatment and care that meets their specific needs.
Each year, hundreds of activities take place worldwide, bringing together communities, schools, businesses, hospitals and organisations through events held in public spaces, workplaces, healthcare facilities and online platforms.
Cancer occurs when changes in normal cells lead to uncontrolled and abnormal growth, forming a tumour. If left untreated, these tumours can spread to surrounding tissue or other parts of the body through the bloodstream and lymphatic system, affecting vital organs and normal body functions.
According to the World Health Organization and the International Agency for Research on Cancer, cancer remains the second leading cause of death globally. About one in five people will develop cancer during their lifetime, while approximately one in nine men and one in twelve women will die from the disease.
The global cancer burden is expected to rise sharply in the coming decades. More than 35 million new cancer cases are predicted by 2050, representing a 77 percent increase from the estimated 20 million cases recorded in 2022. In that year alone, cancer claimed 9.7 million lives worldwide.
Lung cancer remains the most commonly diagnosed cancer, accounting for 2.5 million new cases globally. Female breast cancer ranks second, followed by colorectal, prostate and stomach cancers. Lung cancer is also the leading cause of cancer-related deaths, followed by colorectal, liver, breast and stomach cancers.
Experts estimate that over 40 percent of cancer deaths worldwide are linked to preventable risk factors such as tobacco use, alcohol consumption and high body mass index. While individuals are often blamed for these risks, public health experts stress the importance of creating healthier environments and addressing the commercial factors that drive harmful consumption.
The World Health Organization estimates that an additional 3.7 million lives could be saved each year through effective prevention strategies, including vaccination, early detection and timely treatment, particularly for common cancers such as breast, cervical, colorectal and prostate cancer.
Cancer continues to have a disproportionate impact on low- and middle-income countries, where about 70 percent of cancer deaths occur. These countries often lack access to adequate screening, treatment and support services. This inequality is especially evident in breast cancer outcomes, where survival rates are significantly higher in countries with strong healthcare systems.
Beyond its human toll, cancer also places a heavy economic burden on societies. The total global cost of cancer is estimated at 1.16 trillion US dollars, driven by healthcare expenses, lost productivity, reduced quality of life and premature death.
World Cancer Day serves as a reminder that while the global cancer burden is growing, millions of lives can be saved through prevention, early detection and equitable access to care.
