Dave Coulier is battling cancer — again.

The “Full House” actor, 66, revealed Tuesday that he’s been diagnosed with tongue cancer, seven months after announcing he had beaten his battle with Stage 3 non-Hodgkin’s lymphoma .

“To go through chemotherapy and feel that relief of whoah, 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,” Coulier said on “Today.”
