Sis-in-Law needs a Prayer filled miracle

Another amazing update.... The power of Prayer, no doubt!
SIL is doing well. All artificial life helps have been 100% removed. PT is making her stand up every day getting ready for her 1st walking steps since a month ago. Today they are doing detailed scans of the left breast and abdominal and chest areas, and will follow up with an MRI on Tuesday pin-pointing on what the CT's show today.
Now she has to start facing what she and her mother chose to avoid a year ago, that landed her where she is. To that end, a slight change in prayer focus that they fully understand and grasp what still needs to be done - dealing with the tumor.

Now time for a little rant on the part of my wife and I (another point of prayer focus).
MIL is already denying the 1st 3 weeks were as critical as they were, and saying SIL doesn't need to know the extent of it, nor that she was air lifted to one of the best hospitals in the world that just happens to be local to us. She says SIL should never be told. COME ON MOM!!!!! Now that she is back to fully coherent and alert, how can she make her own sound decisions with her husband going forward if she doesn't know?
My wife and I have tried several times to say she needs to take a break for a day or two and let SIL and BIL have some time alone to discuss it all privately as husband and wife. BIL is just too nice of a guy to give her the boot for a day. MIL says that is her daughter and she will not leave her side during all this. I can see in MIL's face the amount of guilt and sorrow she is carrying for not trying to get her to go to a real doctor in the beginning.
