Hi Sherry, Do discuss with your oncologist about supplements and immune boosters. Some cancer types thrive on the extras! Prednisone is a drug oftened used to slow down and shrink cancers, mast cell included, and this is a drug that moderates the immune system because again the cellular growth we know as cancers are often triggered by the immune's system overzealousness and some of the immune mediated conditions that trouble our Berners are from over activity not deficiency.
All the best to you Rose T.
