Lung cancer is a disease that affects so many people; young and old, men and women, smoker and non-smoker. Roy Castle Lung Cancer Foundation is the leading UK charity solely dedicated to supporting people affected by all forms of the disease and leading the charge to improve outcomes, so people can live well for longer with lung cancer.

It is the UK’s biggest cancer killer, with over 36,000 dying from lung cancer every year. It kills more people than breast, prostate and pancreatic cancer combined, and more women than breast and ovarian cancer combined.

It is our mission to ensure everyone diagnosed with lung cancer can live well with the disease for as long as possible.

By taking in part in Smash Sherwood you’re ensuring we can continue to help all those affected by the disease.
