Dave Coulier revealed he is undergoing treatment for tongue cancer less than a year after beating non-Hodgkin lymphoma. Coulier, 66, shared his latest health update during a Tuesday, December 2, interview on the Today show. "To go through chemotherapy and feel that relief of, 'Whoa, it's gone.' And then to get a test that says, 'Well now you've got another kind of cancer.' ... it is a shock to the system," he said, explaining that he was diagnosed with HPV-related oropharyngeal tongue cancer in October.
