I've raised £100000 to help fund the best trial abroad for relapsed brain cancer of our 3 year old daughter Anna Poppy

We are asking for help to raise money to enable our daughter Anna Poppy to the access the best trial for a very aggressive brain & spinal cancer.
Anna is a typical little girl; she loves dressing up as a princess and looking after babies.
Unfortunately Anna was diagnosed with a medullablastoma in December 2017, shortly after her 2nd Birthday. Since then she has endured a 9 hour operation, 6 months of chemotherapy finished off by a intensive high dose chemotherapy where Anna was confined to a room for 5 weeks. Doctors were hopeful and offered her around an 80% chance of a cure.
Throughout the whole process Anna was unbelievably resilient and was always keen to get up and play whenever she could. Treatmemt finished in June 2018 and since then Anna has been in remission, with 2 clear scans, and making a steady recovery. She finally started to eat solid food again in January 2019 and her feeding tube (which she affectionately called Terry) was removed after over a year of being permanently stuck to her face.
Unfortunately, after her 3rd scan on February 4th we received the devastating call to say that the scan showed a tumour in her spine.
Since then we have been told that this means her cancer is now metastatic and very aggressive. The only curative option would be for full radiotherapy to the brain and spine for 6 weeks but there is only a 20% chance this will work.
After that the nhs will only offer palliative care and Anna's life expectancy would be months.
We are unbelievably thankful to the nhs so far but we can not give up hope. We have spoken to other parents in our position and understand that America has several different options for further treatment should radiotherapy be unsuccessful. We are not sure of the exact costs needed until we know which trial would work best but we know it will all need to be self funded.
Time is not in our favour so we would be extremely grateful for any donations you can offer to help us save our little girl.
