Dr G, Seattle's best oncologist, was concerned enough about my spells of vertigo that he has ordered a brain MRI for next week. I've never had a brain scan before (I don't think. Neither of us could remember.). I passed his quick neurological tests - follow the finger with my eye, touch my finger to his, then to my nose -- so this is more on the order of ruling out any brain mets.
My tumor marker has jumped from the previous month, so it's possible that the reduction in tumor size I reported earlier today was due more to the 5FU than to the Megace. But that's something we can't know until we scan that site again in a few months.
The brain MRI is mid-week next week and I see Dr G to get the results at the beginning of the following week. I will report the news when I get it.
Dancing with cancer should perhaps be subtitled living with uncertainty.
