World Cancer Day falls each year on 4 February. It brings people together to raise awareness, improve education, and push for action on cancer care and prevention. The 2026 campaign continues a three-year arc led by Union for International Cancer Control (UICC). The theme is “United by Unique,” which places people and their stories at the centre of care.

The 2026 theme: United by Unique

“United by Unique” runs from 2025 to 2027. In 2026, it asks a clear question: what does it take to deliver care that meets people’s needs. This includes listening to lived experience, removing barriers, and tailoring services with empathy. The aim is simple, better outcomes and fairer systems.

This theme evolved from past equity campaigns. It keeps the focus on practical action, from local events to national policy. Toolkits and visuals are available on the official site so groups can join in.

The global picture in numbers

Cancer remains a major health challenge. The latest global estimates report about 20 million new cases and 9.7 million deaths in 2022. These numbers come from the Global Cancer Observatory, run by the International Agency for Research on Cancer, part of World Health Organization. Trends show rising cases as populations grow and age.

Projections point to sharp increases in many regions by 2035 and beyond, unless prevention and early detection improve. Planning now helps health systems prepare and save lives.

What you can do today

Cancer control does not rest with clinics alone. It starts where we live, work, and learn. Here are direct steps for individuals, workplaces, and communities.

For individuals and families

Know routine screening ages. Learn when to get screened for breast, cervical, colorectal, and other cancers based on your country’s guidance. Ask a clinician if unsure.
Get recommended vaccines. HPV vaccination helps prevent cervical and other cancers. Hepatitis B vaccination reduces liver cancer risk.
Protect your lungs. Keep smoke out of your home and car. Seek help to quit tobacco and nicotine.
Move more, eat well. Aim for regular activity and a diet rich in plants. Limit alcohol.
Know warning signs. New lumps, unusual bleeding, persistent cough, weight loss, or lasting pain need medical advice.
Keep good records. Note your personal and family history. Bring your list to appointments.

For workplaces and schools

Create smoke-free and vape-free campuses.
Offer on-site HPV vaccination where allowed, or partner with local clinics.
Host a screening sign-up day with local providers.
Add sun safety rules for outdoor workers and students.
Provide paid time off for screening and treatment visits.

For community groups and local leaders

Translate materials into local languages.
Set up transport support for screening and treatment visits.
Map nearby services, including palliative and survivorship support.
Track what works and share your results with regional health teams.

Planning an activity for 4 February

Use this quick planning table to move from idea to action. Adapt it to your context.

Goal	What to do this week	Who to involve	Measure of success
Raise awareness	Host a short talk or webinar on screening and vaccines	Local clinician, patient speaker, school or HR lead	50 sign-ups, 30 attendees
Boost screening	Partner with a clinic for stool tests or mammograms	Clinic manager, community health workers	100 kits given, 60 returned
Support patients	Launch a ride or meal-train network	Volunteers, faith or civic groups	20 active volunteers, 40 rides
Advocate	Ask officials to fund a registry or navigation program	Health dept, elected reps, NGOs	Meeting held, public letter issued

How to talk about cancer with care

Words matter. The 2026 theme calls for empathy and respect. Try these tips when supporting someone.

Ask open questions, then listen.
Offer specific help, like rides or child care.
Check before sharing anyone’s story online.
Avoid blame. Cancer has many causes.
Include caregivers. They need support too.

Policy moves that make a difference

Policy change saves the most lives. Here are proven areas to push.

Tobacco control. Raise taxes, restrict ads, and enforce smoke-free spaces.
Vaccination scale-up. Expand HPV and hepatitis B coverage, including catch-up drives.
Screening access. Fund programs that reach rural and low-income groups.
Pathology and imaging. Invest in labs, radiology, and trained staff.
Data systems. Build or strengthen cancer registries to guide spending.
Navigation and palliative care. Support patient navigators and pain relief access.

Many of these actions appear in toolkits from UICC and allied groups. Use them to brief decision makers and track progress.

Common mistakes to avoid

Waiting for symptoms rather than following screening schedules.
Relying on one channel. Use clinics, schools, and community leaders.
Planning an event without a follow-up path to services.
Leaving out caregivers and survivorship needs.
Talking only about treatment, not prevention and early detection.

Why it matters

Behind every statistic is a person and a family. People-centred care respects culture, income, gender, age, and disability. When we design services around real lives, more people get screened, start treatment sooner, and complete it with fewer hurdles. That is the heart of “United by Unique.”
