My sister is a M.D. but has opted for natural and alternative for her breast cancer. She has tried some standard such as laser surgery when the tumor got too large. It seems that the most success that she has had is with Frankincense.
She tried Cesium Chloride but did not seem to have a lot of success with it.
She also tried blood root / black salve which did eat away a lot of cancer but did not get it all.
