Thinking of her and hoping the best.
But on that occasion let me give you a hint to the Germanic New Medicine: http://www.newmedicine.ca/
It might be of help to understand how the body works and how we have been misled over the last decades especially on cancer. It ties into all the other evil shit and the biggest problem here is the chemo and panic that kills the patient.
Try to read and understand it, try to see if you can find the conflict of your mother and how long it lasted / what solved it. Hope you can find something and can talk to her to ease her panic and make her understand that what happens is not a coincidence and that it is natural.
All the best!
