 Yeah. And then, like I said, not only for finding it, but like our daughter, okay, she has cancer. She goes on what's called a PARP inhibitor. After three or four sessions, is it working or not? They do the PET scan. They can tell. And if it's not working, they change up to a different immunotherapy. And then, you know, on her last PET scan, it was clear that the cancer had spread. There wasn't going to be a cure.
