Funds needed for BRAIN TUMOR surgery

My sister is a 25year old student who was diagnosed with right CP angle schawannoma (brain tumor) a month ago for which she undergone a surgery to drain brain water and placement of shunt and another surgery to remove tumor but doctor took out small tumor part and send it for biopsy. Now another surgery is required to take our the tumor completely. Due to big size of the tumor it cannot be removed with radiation. My sister is unable to walk or talk right now. We need your help to get her surgery done as soon as possible as whatever we had we spent in her last surgeries. (Donations only - NO SADQA or ZAKAT amount please)
