World Lung Cancer Day 2025 will be observed on August 1, a global event held every year since 2012 to raise awareness about lung cancer — its risk factors, prevention, early detection, and treatment innovations. It is also a day to honor patients, survivors, caregivers, and healthcare professionals working in the fight against this disease.

Why It Is Observed

The purpose of World Lung Cancer Day is to:

• Spread awareness about risk factors such as smoking, air pollution, occupational hazards, and genetic causes.
• Encourage early detection through regular screenings, as early-stage diagnosis significantly improves survival rates.
• Remove stigma associated with the disease, as many believe only smokers are affected, but non-smokers and those exposed to polluted environments can also develop lung cancer.
• Promote research and equal access to advanced treatments, and support fundraising campaigns for better care worldwide.

Theme of 2025

The theme for World Lung Cancer Day 2025 is:
“Breaking Barriers: Championing Early Detection and Equal Care.”
This year’s focus is on:

• Breaking social, financial, and geographical barriers that prevent people from getting timely check-ups and treatment.
• Ensuring equal access to healthcare for all, especially underserved communities.
• Highlighting the importance of screening programs that can detect cancer at its earliest and most treatable stage.

How It Is Marked

On this day, global health organizations like FIRS (Forum of International Respiratory Societies), the American Lung Association, and the Lung Cancer Foundation of America launch awareness campaigns, host webinars, share patient stories, and encourage people to use hashtags like #WorldLungCancerDay, #WLCD2025, and #ScreeningSavesLives to spread the message online.
