CanSAR is a not for profit group of volunteers who never stop spreading the message that radon gas is the leading environmental cause of cancer deaths. Radon gas accounts for up to 14% of lung cancer deaths in the U.S. according to the World Health Organization.  Very few people are aware that over 21,000 individuals in the US and over 2000 in Canada die annually from radon-induced lung cancer.

If you visit the CanSAR website you will see the many stories of their members who were not aware that radon was present in their homes until after their diagnosis.
