Any kind of disease can severely impact multiple aspects of the life of its victims and going through it can be a devastating experience for them or their loved ones. Receiving a potentially lethal diagnosis like cancer treatment, and realizing to live with the restrictions of cancer can cause numerous troubles. According to the World Health Organization, cancer is the second leading cause of death globally, and about 1 in 6 deaths is due to cancer. Approximately, 70% of deaths from cancer occur in low and middle-income nations. It is very important to aware more and more people to realize the seriousness of this disease, and thus, the World Cancer Day is marked every year on 4 February to bring up awareness about cancer and to promote its prevention, detection and medication.

The World Cancer Day is now directed by the Union for International Cancer Control (UICC) to support the goals of the World Cancer Declaration, written in 2008. Initially, World Cancer Day was founded on 4 February 2000, at the World Cancer Summit Against Cancer for the modern millennium, which was organised in Paris. The Charter of Paris Against Cancer was established to prevent cancer and similarly comprised an article defining the anniversary of the document's official signing as World Cancer Day. The document was signed at the Summit by the then General Director of UNESCO, Koichiro Matsuura, and then French President Jacques Chirac in Paris on 4 February 2000.

Today, the main goal of World Cancer Day is to considerably curtail this disease and it is a service to mobilize the international community to stop the mistreatment of preventable suffering from cancer. This day is similarly observed as a campaign to create to resonate, encourage modifications and mobilise activities. It proceeds with multiple years and extends an opportunity to develop endless influence by boosting public acknowledgement and engagement of people.

The UICC has decided an exclusive theme for the years 2019 to 2021, and it stands as “I am and I will”. The organisation has decided that 2021 will be the ultimate year of “I am and I will” campaign, which indicates that our actions influence everyone around us, within our communities and cities, and also beyond the borders sometimes. This year the organisation primarily strives to withstand the power of alliance and united efforts. The year 2019 was also progressive, and the UICC saw supporters and leaders around the world indicating the brave and heroic activities required to accelerate further progress for a world without cancer. And this year, the UICC is expecting the same amount of support from people all around the world.

It is incredibly crucial to get rid of the myths that people incorrectly assume about cancer, and educate people about the indications and symptoms, and the significance of screening for timely detection. It is furthermore important to pursue a healthful lifestyle, and sharing of survivor tales, which conveys a message of faith and enthusiasm. More than 30% of cancer cases could be prevented by modifying lifestyle or avoiding the risk factors. World Cancer Day precisely targets myths, raises awareness, and refuses multiple stigmas related to cancer. Multiple programs are organised on World Cancer Day to show support for those affected by cancer. One of these programs is #NoHairSelfie a global movement to have “hairticipants” shave their heads either physically or virtually to show a symbol of courage for those undergoing cancer treatment. It is important to notify people about the significance of regular screening and check-ups and recognising that our dedication to work will direct to significant advancement in lowering the global influence of cancer.
