In the summer of 2015, I underwent brain surgery for a rather large meningioma (tumor) in my left frontal lobe. It was causing a huge amount of swelling and what we in the neurology field refer to as "mass effect" and "midline shift," which is shop talk for my frontal lobe was pushing on my parietal lobe and the left side of my brain was on the right. Not fun stuff at all.
I had no time to really ponder much of anything as I was immediately admitted for tests and surgery. Cutting my skull from ear to ear, my neurosurgeon adeptly removed the tumor. A gross total resection, as we call it. And it was a success. Tumor gone. Job well done. Ordeal over? Well, not so much.
