Importance of World Cancer Day

Cancer is a condition in which some cells in the body develop uncontrollably and spread to other parts of the body. Globally, cancer is the leading cause of mortality, accounting for over one crore deaths in 2020. In India, the incidence rate was reported between 19 and 20 lahks (estimated) cases in 2022. Usage of Tobacco, prolonged consumption of alcohol, unhealthy food habits, lack of physical exercise, and exposure to air pollution are all risk factors for cancer.

Low and middle-income nations face a unique challenge in addressing the cancer risk caused by several chronic illnesses. In addition, these nations had shown poor cancer prognosis due to a lack of education, delayed diagnosis, and low access to affordable treatment. In developing countries, too, the lack of cancer awareness leads to delay in diagnosis. A study reported in 2020, was conducted in four major centres in India, where the majority of cancer patients seek treatment for the first time only when they are in their advanced stages. The literacy rate and low income greatly influence cancer awareness. In India, people with higher incomes and literacy levels were more aware of cancer than others.

To conclude, general awareness of cancer screening, prevention, and treatment is low among the Indian and global populations, especially in low and middle-income with poor literacy rates leading to an increase in cancer prevalence, and there is an urgent need to fill the lacunae with proper education. World Cancer Day brings attention to how important it is to prevent cancer, find it early, and treat it.

History of World Cancer Day

On February 4th, 2000, the World Summit Against Cancer for the New Millennium was held in Paris, marking the beginning of World Cancer Day. The introduction of World Cancer Day is a key component of the Paris Charter, which also seeks to advance cancer research, prevention, patient care, awareness, and worldwide mobilisation.

Prevention of Cancer

Although many forms of cancer are not preventable, some people will still be diagnosed with cancer even if they lead a healthy lifestyle. Cancer risk can be lowered in a number of ways, including: 

• Consuming a nutritious diet high in fruits and vegetables and low in processed foods and red meat
• Regular exercise and maintenance of a healthy weight
• Abstaining from the use of tobacco products 
• Minimum alcohol consumption
• Taking precautions against ultraviolet rays include using sunscreen and wearing protective clothing
• Participating in the recommended cancer screenings on a regular basis
