Help my sister fight cancer

I am asking for donations for my sister, Brittany. She is unaware I am asking for donations as I know she would rather not ask for help. She is the most independent person I know and tries to fight every battle herself. As a family we are asking for donations to help pay for hyperbaric chamber treatments. She has been battling stage 4 metastatic melanoma cancer for over two years now. Tumors have been found in her breast, brain, liver, kidney, lung, stomach and the latest at the base of her skull. She has done 4 rounds of radiation to tackle the tumors in her brain, kidney, stomach and the tumor at the base of her skull. She has been taken off immunotherapy as it is no longer working to keep the tumors away. After learning about this treatment we are hoping that it will give her good results. It is not covered by insurance, unfortunately. With this money she will be able to purchase the cancer package offered.
