Interview With Dr. Jason Fung


Jason. Welcome back to the podcast. It's great to have you on paul. Thanks for having great to be here. We're gonna have a great discussion today. I really loved the new book. The cancer code. And i gotta admit when i dug into the book. It was really what i expected. I was thinking would be more along the lines of fasting. How that could help prevent maybe treat cancer given your background fasting but it was so much more than that. I mean that would have been a great book but this goes really deep into cancer and the evolution of our thinking of cancer over so many years so congrats. I really enjoyed this. Oh thank you very much. And i think that's sort of when i started looking at the issue of cancer. That was sort of how i got into it. Which is why you know most people. I would think think it's going to be about all about sort of fasting and nutrition and cancer but as done sort of deeper into the topic of cancer. There's just so much else going on because clearly cancer is a much more. Broad problem than just attrition because we know things like smoking for example has nothing to do with nutrition. What you eat if you smoke your risk of cancer just goes way way up saying with the best for example. You've exposed as fast as it doesn't really matter what you eat. You're you're great risk of developing a museum which is the type of lung cancer. So that's sort of while it was sort of how got into it as it developed as looking through it more became More and more the question which is never really answered. I think that is really important. Is the sort of how we think about what this problem really is. That is what is cancer. And that's i think one of the greatest remaining medical mysteries because most of these other diseases that we face we sort of know what's causing that. So even when we get a new virus like poof nineteen for example within a few months. We've got this virus like look you know it's still kicking our bod but we've sequenced. We figured it out. It's this is the virus. This is the sequence you know. The dna sequence. This is how it gets in. We've said okay it's the ace two receptors. You know you get at the site of storms. We know so much about it. Even within six months of this sort of brand new disease coming up which has greatest fascinating. Yeah something like hiv. For example it took us years to figure out the actual virus going from age hiv to sort of treatment whereas now you know thirty forty years down the line. We figured out what this virus looks like. We figured out know where detaches we figure so much. Stop so quickly but the problem is that with cancer. What is this disease. Such a strange disease because it's a common disease. It's the second biggest killer of americans yet. If you were to ask the question of what is this disease. People have no idea. Most experts have no idea like you ask the american cancer society and it says well. It's a disease of genetic mutations and that's not really correct because if it was simply a matter of genetics that is You know just bad luck genetically then. Why does environment play such a huge role in this genetic disease. That is if you have a disease. Such as cystic fibrosis sickle cell anemia. All these genetic diseases they passed on sort of mother to child or they have a significantly higher risk in we can identify the genes that are associated with it on the other hand. It doesn't matter if you're japanese if you're african if occasion If you smoke you're much more likely to get lung cancer. So it's not a genetic disease in that sense yet. People have been saying it's genetic disease donate disease and the problem with that. Is that if you don't understand what causes it. Your research sort of goes in the wrong direction that is looking for these genetic mutations and they progress in cancer has really slowed to a halt. Like if you think about how many genetic sort of tours for cancer we have. It's very very few the number of medications that makes a difference to cancer. You can count on one hand in most of those were developed in the early part of the sort of late nineties early two thousands rates with that was twenty years ago and whereas all these great genetic cures for cancer. We just don't see them in because it's not nearly a genetic disease and we have to sort of understand further and this is this is really an exploration of how the way we think about cancer has changed over the last little bit because there's been a huge paradigm shift from being a genetic disease tomorrow logical evolutionary disease which has huge implications for treatment.
