About World Cancer Day
World Cancer Day on 4 February is a global day to raise awareness of cancer, encourage prevention and early detection, and support everyone affected by it. It is led by the Union for International Cancer Control (UICC) and traces back to the Charter of Paris signed in 2000.
Cancer touches almost every family in some way, whether through a diagnosis, caring for a loved one or loss. World Cancer Day brings people together to raise awareness, reduce fear and stigma, and push for better prevention, early detection, treatment and care for everyone.
The day traces back to the Charter of Paris Against Cancer, signed at the World Summit Against Cancer in Paris on 4 February 2000. It is led by the Union for International Cancer Control (UICC), a global network of cancer organisations.
How it is marked
Hospitals, cancer charities and health departments hold screening camps, awareness talks and events that honour patients, survivors and carers. Schools and workplaces share information on healthy habits, such as avoiding tobacco, staying active and knowing the early warning signs. In India, where tobacco use is a major concern, many campaigns focus on quitting tobacco and regular screening. Many people also use the day to check in on friends and family members going through treatment.
What to write
Be warm and honest, and offer support rather than forced cheer.
- Thinking of you today. I'm dropping dinner over on Thursday, and I can drive you to the hospital next week if that helps.
- No pep talk, just love. I'm around this weekend if you want company or a quiet film.
- Thinking of your mother today. She would have loved the garden you planted for her.
