evidence: Seeing this, I harkened back to work of Dr. Tullio Simoncini, who was trendy in alternative cancer therapy circles twenty years ago. In 2005, he wrote a book entitled CANCER IS A FUNGUS A Revolution in Tumor Therapy, which enjoyed widespread popularity. According to Wikipedia, Simoncini "was known for the claim that cancer is caused by the fungus Candida albicans, and has argued that cancer is a form of Candida overgrowth." He advocated for intravenous bicarbonate therapy for cancers and treated patients accordingly. [...] Spoiler alert: I agree. Cancer is not a fungal infection. It would be nice if an inexpensive substance like sodium bicarbonate would provide the key to eradicating cancer. But like many facile theories about cancer, it fails the reality test. [...] Indeed, cancer researchers now theorize, based on these tantalizing clues, that fungi may serve in the future, not just as biomarkers and predictors of treatment response, but also as therapeutic targets! In other words, the time may not be far off when antifungal drugs will find use beyond merely eradicating opportunistic fungal infections acquired by cancer patients receiving immunosuppressive chemo or radiation—but as a way of fighting their tumors.
