 My oncologist was like, I don't know. I mean, we don't know what to do. There's no data. And like, I'm a data scientist. Like, there's no data. We can't tell you what to do. But if you want to look at your kids and say you tried something, and he can wrote out a bunch of different chemo's and chemo combinations and radiation and chemo combinations in pencil and handed it to me, he's like, pick one. And I was like, what do you mean pick one? I was like, you tell me. Like, what should I do? And they just, they had nothing to offer because they just didn't know. And it's not their fault that they didn't know. It's just that there was no way to know. There's like, we're so rare. Even if we were common, there's such huge gaps of information missing across the entire spectrum of cancer care that oftentimes it's just kind of a guessing game when you get to the rare subtypes of even more common cancers.
