Visit with the Neurosurgeon

So, I had my annual MRI and then visited with the neurosurgeon the other day. He told me I was doing so well that I don't need an annual MRI, I only need one every two years for right now. He said they still are unsure what caused the abnormal cells in my brain, but that the worst case scenario was that they were a slow-growing, pre-cancerous bunch of cells. The types he referred to he said take about 15 years to recur generally. He said if I start having a bunch of seizures I need to get checked out, but otherwise not to worry. He pointed out rather nonchalantly that if that area starts to grow or become a problem, he could go back and take twice as much out as last time - and that I would probably not notice any problems and would be back to work right away. Seems funny to me that he talks about brain surgery like it's no big deal. Great news though. I'm really happy to be so much more active and not on any medication. Hadn't been like this for years prior to right medial temporal lobectomy.
