Boy Shaves Head For Buddy With Cancer, Shows Us What Real Friendship Looks Like

When first-grader Vincent Butterfield found out his best friend was sick, he wanted to do everything he could to help.

His buddy, Zac Gossage, of Union, Mo., was diagnosed with acute lymphoblastic leukemia, a cancer of the blood and bone marrow, in June 2013. When Vincent learned Zac could lose his hair from chemotherapy treatments, he did what he could to make sure his friend didn't feel alone.

"Vincent is like that. He’s a compassionate little boy. When he sets his mind to it, he does it,” Vincent's mother, Karen Butterfield, told NBC's "Today."

Zac's mom says the boys have an incredible relationship. "I’m grateful that he has such an amazing friend,” Stacy Tooley told the outlet.

Acute lymphoblastic leukemia is the most common childhood cancer, and patients have a survival rate of more than 90 percent, according to a 2012 study conducted by the University of Colorado Cancer Center.
