I wrote a post on eastern healing methods here, i would highly recommend the meditations for your daughter, i will be putting up self healing methods shortly. There is also a man I have found selling medicine that helps illnesses such as cancer, i am about to try some of it myself for my arthritis-its herbal, and was until recently very secret handed down master to student.
I can also offer to send some healing to her if i have her permission- where exactly is the cancer? How advanced?
