Dave Coulier has been diagnosed with cancer.

The “Full House” star, 65, revealed on Wednesday that he has stage 3 non-Hodgkin lymphoma.

He told Today that he first noticed his symptoms several months ago when he got a cold, and then noticed he had a large lump in his groin.

“It swelled up immediately,” he said. “I thought, ‘Wow, I’m either really sick, or my body’s really reacting to something.’”

Coulier visited a doctor and was informed of his diagnosis, which came as a complete shock to the actor.

“The first thing I said to them was, ‘Wait a minute — cancer?’” he recalled. “(I was) feeling like I got punched in the stomach because it never happens to you. You always hear about it happening to someone else.”
