Got the result for the gum and jawbone biopsy ... and good news! It was an amalgam tattoo after all. Fantastic to be cleared of the worry of melanoma!
Also saw my radiology consultant about the MRI result and the queries that I had about size differences. Apparently the reported sizes vary because the MRI 'slices' may not be in quite the same place each time. So as a tumour is a 3-dimensional entity one slice may be wider or longer than another. As the differences were only 0.1cm that was reassuring to know. She said that should Fuss increase in size on the next MRI then it would need looking into, but for now the 0.1cm increase might be just because of a different view.
The specialist also suggested that we go to bi-annual MRI's from now on but I said that, unless and until my symptoms ease off a bit, I would prefer to keep to annual scans for the time being. She agreed to this and so my next MRI will be January 2014. She is unable to explain why I get these constant headaches and nausea, nor the tinnitus. Nor my memory difficulties ... but she reassured me that my brain shows absolutely no sign of Alzheimers disease!
So, all in all, an encouraging week on the health front! GOOD ...
