Help my sister have a bone marrow transplant and live her life for her baby

As my sister was pregnant, she was diagnosed with Hodgkin Lymphoma. In God's grace, she was born normal and presently a year old. My sister underwent 6 cycles of chemotherapy and underwent a CT scan and was diagnosed with Tuberculosis. As weeks passed, her health deteriorated and soon was paralysed. She can't walk and we got to the point that I carried her up the stairs to her room. We then brought her to a proper hospital and there, after her MRI, she was found to have a mass growth behind her throat hitting her spine causing the paralysis. She is now presently having chemotherapy and her doctor suggested she have a bone marrow transplant. We can't afford it as me and her husband only make minimum wage (450php or $10 a day). I hope you find it in your heart to help because I want her to watch my niece grow. Godbless you.
