"Jeopardy!" host Alex Trebek is teaming up with the World Pancreatic Cancer Coalition for a new public service announcement.

Trebek says he wish he knew about the symptoms of the disease ahead of time.

"I wish I would have known sooner that the persistent stomach pain that I experienced was a symptom of pancreatic cancer,” says Trebek. “Other symptoms include mid-back pain, unexplained weight loss, new onset diabetes and the yellowing of the skin or the eyes."

Trebek announced his diagnosis with stage 4 pancreatic cancer back in March.

Since then, he's been actively raising awareness.

Trebek is encouraging people to educate themselves on the risks and symptoms, and to spread the word on social media.

Trebek shares in the PSA that in most countries, pancreatic cancer is the only major cancer with a five-year survival rate in the single digits.

According to the American Cancer Society, for all stages of pancreatic cancer combined, the five-year survival rate is 9%.

World Pancreatic Cancer Day is Nov. 21.
