 If there is a brain tumor related kind of headache that it's like one that's like right on the top, nobody complains that like it hurts like right here. Is that a thing? Is that literature supported? The vast majority of headaches are not related to brain tumors. And so headaches are so multifactorial, migraines, tension headaches, you know, too much computer time, too much caffeine, too little caffeine, you know, no hydration. There's so many things which cause headaches. Thankfully, the brain does not have pain receptors. And so typically we don't have vocal headaches because of a brain tumor. So when people do have headaches, typically it's from pressure in the brain. So if a tumor can get so large and it's taking up pressure, it's putting, you know, pressure on all the normal structures causing a lot of swelling, we can get a global headache because of that. But in general, we typically don't get pain here or here in a certain place because of a brain tumor.
