"Jeopardy!" host Alex Trebek to undergo another round of chemotherapy

“Jeopardy!” host Alex Trebek announced Tuesday on "Good Morning America" that he will undergo another round of chemotherapy for stage 4 pancreatic cancer, a month after returning to work and telling fans that he's "on the mend."

Why it matters: Despite overall cancer survival rates improving in the U.S., pancreatic cancer is known to be very deadly and tends to be diagnosed at a more advanced stage.

What he's saying:

  • "I was doing so well. And my numbers went down to the equivalent of a normal human being who does not have pancreatic cancer. So we were all very optimistic."
  • After the start of immunotherapy, Trebek said he lost about 12 pounds in a week and his numbers skyrocketed "to much higher than they were when I was first diagnosed. So, the doctors have decided that I have to undergo chemo again and that's what I'm doing."
  • "When [the cancer] happened early on I was down on myself. I didn't realize how fallible each of us is in his or her own way … I talk to the audience sometimes and I get teary eyed for no reason. I don't even bother to explain it anymore, I just experience it. I know it's a part of who I am and I just keep going.”

Pharmaceutical investments in cancer drugs soar despite few results

Pharmaceutical investment in cancer treatments has risen drastically over the past decade, as has spending on cancer drugs, but the results have been comparatively small, UC Hastings law professor Robin Feldman argues in a WashPost op-ed.

Why it matters: Every dollar invested in cancer is a dollar that isn't invested elsewhere — for example, in antibiotics.

A New York University study has identified a pattern of lung cancer in mice exposed to the same amount of e-cigarette vapor as someone who's been using e-cigs for approximately three to six years.

The big picture: As vaping deaths and illnesses rise, the medical community and health regulators are increasingly concerned about the unknown effects of e-cigarette use. While e-cigs were originally meant to help cigarette users ween off smoking as a whole, vaping has dramatically increased in popularity in recent years, especially among young people.

3 scientists — 2 American, 1 British — won the 2019 Nobel Prize in medicine for studying how cells sense and react to varying oxygen levels, per AP.

Why it matters: The Nobel Committee said the scientists' work has "greatly expanded our knowledge of how physiological response makes life possible" and kickstarted new strategies to fight anemia, cancer and other diseases.
