BOISE -- Diagnosed with brain cancer at age 13, Trevor Schaefer has been a huge advocate of eradicating disease.
KTVB caught up with Trevor at Whole Foods in Boise Wednesday promoting his new book, 'The Boy on the Lake.'
KTVB has also been following Trevor's story for years.
Most recently, his efforts to pass Senate Bill 50, also known as "Trevor's Law," which is a disease cluster bill designed to help communities determine whether there is a connection between "clusters" of cancer and other diseases, and contaminants in the surrounding environment.
Trevor was diagnosed with a malignant brain tumor in 2002, the same year there were four other cases of childhood cancer in the same area in McCall.
On Wednesday, Trevor and Whole Foods teamed up to raise awareness about his cause-- and the benefits of healthy eating.
"One of our main focuses with Trevor's Trek foundation is nutrition and the role that nutrition plays in preventing and treating cancer," said Trevor.
Whole Foods also donated five percent of Wednesday's sales to the Trevor Trek Foundation.
As for Trevor's Law, it's expected to get a hearing in the next couple months and Trevor's hoping this year, it will pass.
