Maybe the rad seed implants would help her. After everything else helped, I was given Radiation seed implants . This was supposed to prevent any more cancer from rearing it's nasty head. I have been thru hell and I think it was from the implants. From under the chin, while you are put in a coma, they insert the implants thru the chin into your tongue and leave them for a few days. You are kept in a sleep and quarantined with only the Dr or nurse to get near you to check on your condition, as you are radioactive. The after affects are severe and I would hate to see your mom go thru more pain but if it would do the job then it's worth it.
