Full House star Dave Coulier, 65, told the Today show that he was diagnosed with Stage 3 non-Hodgkin lymphoma five weeks ago. He shared that he has been undergoing treatment for the 'aggressive' blood cancer, including three surgeries and chemotherapy. 'It has been a rollercoaster ride for sure,' he said, as he joked he looked like a 'baby bird' due to hair loss as a result of his treatment. #fullhouse #celebritynews #davecoulier
