Dear Pranjal,
I am very sorry to hear about your loss.My Mom is battling with Cholangio ca in India as well. You can get similar medical care in India nowadays as you would anywhere in the world.But unfortunately the disease is usually diagnosed in advanced stages.A lot of patients only tolerate a stent placement which is done for palliative reasons. I can understand what you must be going through and can relate with it . Please let me know if I can be of more help to you in anyway. You did everything right.Its the disease which is dreadful .
