I am really sorry to hear this news. However, i think the best remedy at this stage is the DUA bcz allah is the best of the best friends of ourz and none can help us but him.
Doc r present for the mere purpose to diagnose the disorders' in ones body and acutally its allah subhan tallah who gives us the shafa and strength to recover from all sort of diseases.
my dua is with u and ur family :)
