Dh had a form of cancer as a child. It had a 5% survival rate. His odds were less than that as it had already metastasised when he was diagnosed. His parents (and family) are people of faith and they upheld him in 24/7 prayer for as long as it took (year plus). He survived.
He was told that he would be sterile from the treatment. We have four dc.
He is a doctor. He doesn't give patients or their families false hope but he does believe in miracles. He is one.
Praying constantly that Aillidh will be healed and that all those supporting her through this valley will be encouraged, strengthened, resolved. His grace is sufficient.
