“Full House” star Dave Coulier’s battle with cancer is getting tougher, according to his wife. It was announced in October that Coulier was diagnosed with stage 3 non-Hodgkin lymphoma. “He has some really tough days, and as chemo has been accumulating it gets a little tougher and more difficult,” she told WXYZ ABC 7 in Detroit this week.

Beloved Full House star Dave Coulier revealed back in November that he had been diagnosed with a “very aggressive” form of stage three non-Hodgkin's lymphoma and that he was in the process of undergoing chemotherapy treatments.
