So you do have cancer? Or you think you might have cancer?
Here's the deal with this nasty little buggar: What kind you have and how far it's progressed are going to really set the stage for the kind of treatment that is planned and how much that will affect someone's studies. The thing with cancer is, "fighting" it is really mostly just waiting. Waiting to have a test, waiting for results, waiting for treatment, waiting for more tests, etc.
The point is, with all that waiting going on, the hardest part is to not let your imagination get the best of you. Because it can eat you alive.
