Your sister is on the right track and she is among most doctors that when faced with cancer themselves know full well that poisons do not work and will opt for alternative treatments. She may want to look into BX Antitoxin, it has no side effects and targets the cause. Conventional treatments treat the symptoms, killing off tumor cells by way of killing off healthy cells too; a good alternative like BX Antitoxin does not harm healthy cells but targets the cancer at its core. Have her look into it, http://www.jesichashope.org
