does a brilliant job in guiding you in the right direction as it covers various types of cancers and which natural treatments work best for those different kinds individually. Cesium chloride is one of the most effective treatment as most tumours are acidic in nature and need to urgently be neutralized, or alkalized.
It has the power to even increase intracellular PH, whereas bicarbonate of soda only increases extracellular PH of tumors (as far as I know). For this reason it is highly effective in most cancers since most tumors are acidic. Some I believe are NOT acidic, so you need to be careful when doing your research and find out what works best for you specific type of cancer.
