"Over the weekend I lost my youngest son to a condition called hydrocephalus that was pretty much a malignant, invasive midline brain tumor, brain cancer," Cannon said. "It's tough."
According to Mayo Clinic, Hydrocephalus is the "buildup of fluid in the cavities (ventricles) deep within the brain." The excess fluid puts pressure on the brain and can "damage brain tissues and cause a range of brain function problems."
On Wednesday, Cannon shared the photo and talked about what it means to him.
