About a year ago, long-time Jeopardy! host Alex Trebek announced on social media that sadly, he had been diagnosed with stage 4 pancreatic cancer. It was news that shook many fans, and viewers of the show, especially a diagnosis as scary as this particular sickness. 1 year passed as Trebek stayed relatively silent on social media (as one can imagine), that is until now. Alex Trebek has just released a video on social media with a long-awaited update on his health.
