Following the tragic announcement, Fontana and Oz star Dean Winters, 57, created a GoFundMe page to help cover the Adam’s medical costs.

“As many of you know, our friend and brother Granville Adams has been diagnosed with cancer,” Fontana wrote on the fundraiser’s page. “In only a few months, the medical bills have skyrocketed to astronomical levels. Not only does he have to battle this ruthless disease, but now he has to fend off the hospital bills the insurance company refuses to pay.”

“We want to gather together and show Granville our love by clearing this quarter’s bills, giving Granville concrete support in his fight against this vicious disease,” he continued

At the time of Adam’s death, the campaign had raised almost $100,000 in contributions.
