Clear again, and a discussion of scans

Yesterday I went back to the Western General Hospital for another follow-up appointment. All was well. The doctor even checked my legs this time (with all the poking and prodding I receive each time, no one has thought to do that before).

We talked about the possibility of another CT scan and three arguments were suggested as to why it wouldn't really be a good idea. First, it is more or less unnecessary after a certain period of time (though the Australian doctors thought two years, here they think one), and any relapse is likely to be signalled through clinical signs anyway (e.g. loss of appetite, difficulty swallowing, coughing up or passing blood, weight loss, lumps and bumps, difficulty breathing, and so on). Second, since I have already received the maximum amount of radiation they are ever going to give me (lest they damage my spine),* each scan adds a little more radiation to this (only a fraction of what I received in treatment, but there's no point pushing it). Third, and this was the point he elaborated the most, he believed that the more scans you have, the more anxious you become, since scans pick up more than cancers, so that every little dot becomes a reason for worry.

There was, of course, a fourth reason which he didn't mention: cost. It would be interesting to know the extent to which this was a factor in his recommendation. I don't think that in principle this is an unreasonable consideration as I don't think we ought to do everything possible to keep people alive. It is possible to over-invest in health. However, I don't know enough about the NHS and the UK budget to make any kind of informed decision about the relative investment in health here in the UK.

Nonetheless, at the end of the discussion, he agreed to arrange a scan prior to my next appointment in three months in order to mark the two year milestone.

Every now and then I struck afresh by how surprising it is to be here: (a) alive and (b) in Edinburgh** doing a PhD. Praise God!
*I can't remember if I ever mentioned on this blog the strange sensation I got a few weeks after the end of radiotherapy. For many months, whenever I walked for more than 5 minutes, my feet would tingle. I told my oncologist about this and he told me to nod my head. Being taken off-guard by the apparent nonsequitur of the request, I complied, only to find I could generate the same tingling sensation just by moving my head. He explained that the radiotherapy had started to affect my spinal column and so when I stretched it (through walking, or just nodding my head), then I felt that strange sensation. It was a little off-putting at the time, but on reflection, it showed that they had indeed given me the maximum dose of radiation. Earlier, the radiologist had referred to the real possibility of burning a hole in my oesophagus if they gave me a little bit more than I had.
