My son Avigna sharma age 8years is undergoing bone marrow transplant at kokilabean dhirubhai ambani hospital. He was reffered from tata hospital mumbai as waiting period for BMT was of 12 months there. He was diagnosed with Acute lymphoblastic luekimea in the year 2016 and his treatment was done at tata hospital but again it relapsed this year on April. And now only bone marrow transplant is his hope for survival. But the cost is really high so kindly help me.
