Thank you for all your kind words.
There's an amazing book called "Cured" by Dr Jeff Rediger about spontaneous remission (some with different types of medical treatment, some not). It's not a cure for anything specifically, but its a fascinating study (by a proper medic) on what threads seem to link people who defeat the odds with cancer and auto-immune diseases. No concrete conclusions, but some interesting threads. Some people seem to make it though despite the odds, and some just don't and its totally unfair and seems random. I'm so deeply sorry to anyone who's seen people go through this or any other cancer. Its grim. I've seen it close up. However I don't believe there's such a thing as false hope. We must all have hope. There are a few, within the sad outcomes of so many, who do live beyond their diagnosis. My mum was one. She survived long enough to get me and my sister into adulthood. Not sure how, but she did.
Sarah has no other options on the table at the moment. She's chemo'd and radio-therapied up to the hilt, and there's only a certain amount that can do. There are immunotherapy trials going on in the UK (so its not German quackery, its science which is constantly evolving, debated, reviewed etc), but her specific type of tumour doesn't fit any of the trials. She chose this option as she has spoken to people who've gone through it and survived, up to 10 years on from diagnosis. She is so loved and valued in her community that people have been willing to chuck a few £ in, whatever they choose, just in-case there's an inkling of hope of keeping her here for longer than the odds pessimistically declare. None of us are in denial, but hope, humour, and a massive groundswell of love and support, and this treatment might just ride her through...you never know. Every limb and digit crossed...
