Cancer is not a fungus, but cancer can be caused by the fungus. But not only, it can be parasites, or often both.
While sodium bicarbonate might destroy tumors, it is just another allopathic treatment. Tumors are a symptom rather than a cause. We all make cancer cells, but when the immune system gets weaker and the blood "dirtier" due to a compromised liver, then those cells grow out of control.
But for me there is no doubt that fungus and parasites are the causes of most cancers.
