Dave Coulier has had a really difficult few years, having received two separate cancer diagnoses and thankfully been declared in remission from both. The former Full House star appeared on The Kelly Clarkson Show to discuss his illness and healing, and the important lessons he learned through that difficult time - including that he was surrounded by toxicity in a way that really worried him. "I feel great today. I'm here to announce that I'm in remission from both of the cancers," Coulier told host Kelly Clarkson.
