In March 2014, I tried to connect a boat trailer to my minivan, ploughed head-first into the closed tailgate and really hurt my neck.

An X-ray showed I hadn’t broken my neck, but the doctors saw something near the back of my brain, at the base of my skull. A CT scan confirmed it was a tumor. The doctor was elated because he found it before I had any symptoms. I had mixed emotions, and it took a while to process the news.
