Alex Trebek is on the mend.

Five months after being diagnosed with stage 4 pancreatic cancer, the beloved “Jeopardy!” host is finished with chemotherapy and has begun production of Season 36 of the enduring quiz show.

“Let me tell you, it’s going to be a good year,” Trebek, 79, said in a video promoting the upcoming season.

Trebek told People in May that some of his tumors had shrunk by 50 percent. At the time, he credited his fans’ well wishes and prayers, in addition to the treatment for the disease, which kills 45,750 people a year, according to the American Cancer Society.

Back in March, Trebek shocked his dedicated following by announcing he was fighting the disease.

In the video message announcing his diagnosis, he said, “Normally, the prognosis for this is not very encouraging. But I’m going to fight this and I’m going to keep working and with the love and support from my family and friends and with the help of your prayers also, I plan to beat the low survival rate statistics for this disease.”

His success so far is a big accomplishment. The odds aren’t usually in these patients’ favor.

“Unfortunately, the prognosis is poor for patients with stage 4 pancreas cancer,” Daniel M. Labow, MD, chief of Mount Sinai Hospital’s surgical oncology division, told The Post. “In general, five-year survival rates are between 5 and 10 percent.”

Season 36 of “Jeopardy!” premieres Sept. 9.
