What about grade I or grade III?

What if I magically knew it was a grade I tumor? I would wait and watch without a doubt. The tumor-related risks are small since my tumor is not close to important parts of the brain. And if it were to start to grow it generally would be slow and I could have it taken out when needed, if that ever happened.

What if I magically knew it was a mixed grade II with III cells? Then I would have it out. And I would probably treat it aggressively -- I would gather information first but I expect that's what I would do. And if this is the case, it's better to do it sooner rather than later.
