World Cancer Day is observed annually on February 4 by the Union for International Cancer Control (UICC). In 2026, it marks the second year of the 2025–2027 three-year campaign with the theme 'United by Unique', emphasising that every cancer patient's experience is unique and that unity in this diversity drives better outcomes. From February 3–5, 2026, the Cancer Patients Aid Association (CPAA) organised awareness and outreach events across India aligned with this theme.

India carries one of the highest cancer burdens globally, with a projected 15.7 lakh new cases in 2025 (ICMR-NCRP data). The five most prevalent cancers in India are breast, cervix, oral, lung, and colorectal cancers. The Government of India's National Cancer Grid (NCG), National Programme for Prevention and Control of Cancer, Diabetes, CVD and Stroke (NPCDCS), and Ayushman Bharat PM-JAY provide institutional responses to this burden.

For Rajasthan, the All-India Institute of Medical Sciences (AIIMS), Jodhpur, and Sawai Man Singh Medical College, Jaipur, serve as tertiary cancer care referral centres. The state's cancer burden is compounded by high tobacco use and limited early screening access in rural areas.
