my advice would be try to alternative therapies such a iv vitamin c. we have just lost my sis in law this evening to breast cancer that had metasises, she was just 43.
we relied solely on chemo, for her the chemo is what made her weak, and her everyday quality of life was ruined.
we were too late to thin of laternative medicine in conjuction to chemo.
gods will was to have her with her.
my prayers are with your mother.
