I concur with Luella and would add that oleander and inositol/IP6 (two key items in the suggested protocol) could be quite effective at reducing and eliminating your tumor.
In addition to taking oleander orally, you can also make your own concentrated oleander extract at home and then use it together with iodine, colloidal silver and a few drops of DMSO topically two or three times a day to help attack and eliminate the tumor. See:
