So that you do not feel bad that this advancement
in BC cancer was not available
in time for
use with your mother, let me also point that it is only inidicated for with people with one tumor and no spread to the lymph nodes, so your mother would not have been a candidate for this type of treatment in any case.
Rest assured that your mother is being given the best treatment for her type, stage, and grade of BC.
Best wishes to you both...
