Alex Trebek, saying he's on the mend, back at 'Jeopardy!'

LOS ANGELES (AP) — "Jeopardy!" host Alex Trebek has returned to work, saying he's "on the mend" after treatment for pancreatic cancer.

The game show posted a video Thursday on Twitter showing the 79-year-old host back on set and promising "a good year" ahead. He actually started work on July 22, his birthday.

New episodes of the upcoming Season 36 are slated to begin airing Sept. 9.

Trebek announced his diagnosis in March. He said he planned to beat the disease's low survival rate with the love and support of family and friends and with prayers from viewers.

The American Cancer Society estimates 3 percent of patients with stage 4 pancreatic cancer are alive five years after being diagnosed.
