Trebek urged viewers to take action and participate in raising awareness to the disease during Pancreatic Cancer Awareness Month this November.

Last month, Trebek told \"GMA\" that he would be undergoing another round of chemotherapy.

\"I was doing so well. And my numbers went down to the equivalent of a normal human being who does not have pancreatic cancer,\" he said. \"So we were all very optimistic. And they said, 'Good, we're gonna stop chemo, we'll start you on immunotherapy.\"

He then revealed things got worse. \"I lost about 12 pounds in a week. And my numbers went sky high, much higher than they were when I was first diagnosed,\" he shared. \"So, the doctors have decided that I have to undergo chemo again and that's what I'm doing.\"

The host said he is struggling to be a source of positivity to people who are also fighting the disease, in a CTV interview earlier in October.

\"A lot of people are coming to me and looking for help, reassurance, and that’s tough,\" he shared, adding that it's difficult, \"trying to be as optimistic as you can when the other person feels none of that. … They feel only despair.\"

Trebek also told CTV that during his battle, he will, \"play it by ear and keep chugging along until we either win or lose.\"
