Mesothelioma Awareness Day is Sept. 26. On this day, patients, family members, doctors and the mesothelioma community raise awareness of the rare cancer to help find a cure. Supporters wear blue and may wear mesothelioma awareness wristbands or ribbons.

It was established in 2004 by Meso Foundation community members, and has been the driving force behind the movement to bring more attention and funding to this cancer.
