I agree with Ann-Marie. It's still unknown why HPV causes Head & Neck cancer in some, and not others. Smoking increases your risk, drinking not as much as smoking, chewing tobscvo, having a history of HPV in the cervix, being HIV, lack of nutrients. It's multiple factors, and take years, even decades for the dormant virus to become cancerous, probably due to being attacked so often, your immune system is then unable to fight off the cells from multiplying, especially when you get older, and or when your immune system is lowered. I often hear the phrase, "Let food be thy medicine, and medicine be thy food." But I would not substitute it for conventional treatment, and consider it adjunctive as Ann-Marie mentioned.
