Fund Sagnik to get treatment for relapsed cancer,Neuroblastoma Stage 4

My son, Sagnik, is 2 years 3 months old. He was first diagnosed with Neuroblastoma Stage IV cancer on 30th August, 2017. He was treated in Apollo Cancer Institute, Chennai and complted Chemotherapies and Bone Marrow Transplant(BMT). He was doing well but suddenly after 3 months of BMT, around 12th March, 2018, he developed a lump over his head. After further diagnosis, doctors confirmed that it has relapsed.
We further consulted with doctors and found that relapse treatment are not available in India.
However, since I was involved with different facebook communities, I came across different hospitals in UK, US etc, where relapse treatment is done. Me, my family and my friends are working to gather treatment details and hospital adress so that we can start next course of treatment as soon as possible. We have contacted several hospitals, organizations so that they stretch their healing hand to us. I will share further details once I get the treatment plan.

Now treatment in overseas is very expensive. Recently I talked to a doctor in Germany who said whole treatment will cost apprx. 0.5 million US dollar. However he extended his support and also thinking if part of the treatment can be done from India. Our treating oncologists are in touch with him and I hope soon they will figure out something. Once we get detailed treatment plan and written cost estimate, I will share them without delay. 

Now I am not the one who will step back for not affording the cost of treatment. I will explore each and every possible way and will knock every door to raise fund so that I can give my son a chance to live.
So, I really need your help and contribution for this mission. I am hopeful that together we can accomplish this mission. Please share my message to wider audience which will help me raise funds.

This is my kid when we was having his happy days:


This is now when he is spending most of his days in hospitals:
