Let's start with the most important thing: you are not alone in this, and you are not expected to understand everything right now. The words "B-cell acute lymphoblastic leukemia" just landed in your life like a bomb, and your brain is probably doing that thing where it hears the doctor, but the words bounce off like they're in a foreign language. That's normal. That's human. And that's exactly why this chapter exists.

We're going to talk about what this disease actually is, what it does inside the body, and why it matters. No jargon without an explanation. No pretending it's not serious. Just clear, honest, plain-language truth. If you only read one chapter in this book, read this one. If you read it and still have questions, that's okay too — you can come back to it.
