I started reading The Opposite of Certainty, a memoir by Janine Urbaniak Reid, because it’s another story about someone with a brain tumor. This time it was the author’s young son. I’m an astrocytoma survivor and I think I’ve read every book there is on brain tumors trying to find myself in the story. Even as I tried, I never quite found the same story, until now.

The family chooses a little of both, waiting and consulting a whole bevy of professionals from herbalists and nutritionists to a chiropractic neurologist and a Qigong master and then later choosing a course of chemotherapy. Once it seems as if everything will be okay, at age 13 the tumor bleeds, leaving Mason with brain damage.

This isn’t the first time, but it is the major way our stories diverge. Although we shared the same type of tumor, a pilocytic astrocytoma, mine was only a pea, not a lemon, like his. I was initially told that I wouldn’t need surgery right away, but within hours that changed, only because I was going to be off my parent’s insurance in a few months.

I had been having symptoms for much longer, but had hid them until my college roommate made me tell my parents. It turned out I…
