Vinny Desautels, 7, grew his hair out for two years to donate it to children fighting cancer.
"I want to help people so they don't have to go to the doctor to fight cancer," Vinny said.
But now Vinny, who lives outside of Sacramento, has been diagnosed with cancer.
"It is Stage 4 aggressive cancer," Jason Desautels, Vinny's father said. "What they found is that he has a significant growth on his hip and in the bone around the eye and behind the nose and on the cheek on the right side."
Vinny's father said his doctors were still trying to determine the exact type of cancer he has.
