As Alex Trebek undergoes a second round of chemo for pancreatic cancer, fans shouldn’t worry about the longtime “Jeopardy!” host leaving the small screen. After a recent interview sparked rumors that he could be planning to step down as the host of the iconic game show, production sources tell TMZ that the show is taped months in advance – as of now, they have tapes into December, so it’s no biggie if Trebek has to miss any episodes.
