World Cancer Day is a global initiative observed on February 4 each year. It aims to unite the world in raising awareness, improving education, and catalysing personal, collective, and government action against cancer. World Cancer Day is also used as an opportunity to educate the public on early warning signs and symptoms, as many cancers are treatable or curable when detected early. This day also highlights that more than one-third of cancers are preventable through lifestyle changes, such as avoiding tobacco and getting vaccinated.

The increase in lifestyle-related cancers in India

Cancer is no longer just a disease of chance or genetics, it is increasingly becoming a disease of the way we live. India has undergone a transformation from infectious diseases and tobacco-related cancers being prevalent as risk factors to having a substantial increase in lifestyle-related cancers, particularly in urban and semi-urban communities.

According to GLOBOCAN 2020 data, India reported over 1.3 million new cancer cases, and this number is expected to rise sharply over the next decade. What is particularly worrying is the increase in cancers linked to lifestyle factors, such as breast, colorectal, prostate, endometrial, pancreatic, and certain head and neck cancers, many of them occurring at a younger age than previously seen.

One of the biggest drivers of this trend is physical inactivity and obesity. India is witnessing a paradox where malnutrition and obesity coexist.Excess body fat leads to chronic inflammation, hormonal imbalance, and insulin resistance, all of which increase cancer risk.
