Proceeds from the cereal will directly impact pediatric cancer research at Roswell Park's Carly's Club, the featured charity for MariOs, says Robin Hace, events coordinator at Carly's Club.
"Those programs are year round ... something to help them escape the rigors of treatment and to, really, normalize their life a little bit," Hace said.
Lucas Lowe of Akron spoke at Tuesday's announcement about MariOs. He received his diagnosis at age 7, Hace said.
Lucas had a big grin on his face throughout the event. Hace said his treatments will continue into 2014.
Mario Williams says the condition has touched his family -- with his father getting a colon cancer diagnosis two years ago.
Carly's Club for Kids & Cancer Research aims to offer support programs to make life more manageable for children diagnosed with cancer and their families -- and to raise funds for pediatric-cancer research seeking cures at Roswell Park Cancer Institute, according to the organization's website.
