My next MRI is tomorrow. I distinctly remember the anticlimax of last year, I even wrote about it. It was no big deal. So why am I so worried?
I've been doing a lot of running recently, and one of the best things about it is time to think. I've not had much time to myself since the baby was born and so it feels like a real luxury to just think for a while. Inevitably at this time of year I've been thinking a lot about head scans, brains and tumours.
I'm not sure if I ever asked, or if I've just forgotten, but I don't know how a tumour starts. Like, why does it begin?
When I was 12 I skied off a cliff. It wasn't intentional; I was trying to avoid a tree. Obviously with a bit of hindsight it wouldn't have been so bad crashing into a tree - no helicopters, splints or head scans would have been involved. On the plus side, I actually own copies of my 12 year old head scans which is pretty cool. And there is no tumour.
So where did it come from? When did it start? Why did it start? Why has this not occurred to me before?
Last week I managed to think my way through a 40 minute run, comparing my tumour to the entire universe (the world does revolve around me, doesn't it?). Either, I thought, it was created by God one day, or... there was an almighty big bang in my head (the cliff THE CLIFF), and then the tumour existed. (I admit, there are some failings to this comparison).
Oliver thinks it was a cell mutation, which makes sense. But even if that's the case, it doesn't really answer my question. Why? Why did it mutate? And why that one, and right then, in that way?
The thing is, I could have all the information in the world about how and why and what to expect, but until anything shows up on a scan it is all theoretical. None of it is worth wondering about even, it's such a waste of energy and worry - until there is a scan to look at. And tomorrow, there will be.
What is also not helping is the fact that I've had three migraines in the last five days. Not really recovering from one when the next hits. The last time this happened I was shovelled into an ambulance and ended up having my head sawn open. Bodes well.
Another thing I've been thinking about is the person doing the scan. They can see the results as it happens right, so they know, like straight away, if there's a whopping great lump of something in your head that isn't supposed to be there. What a weird job to know that about someone and send them merrily off home again to wait for a few weeks until they called in. I don't think I'm going to be able to stop myself staring at them on the way out, to see if they have pity in their eyes.
