Cancers are now the leading cause of death in Western countries. Cancer prevention is a public health issue. Helping patients is a daily commitment. Most cancers can be explained by viral infections (papillomavirus, cytomegalovirus, Epstein-Barr virus, hepatitis B or C) or a metabolic syndrome (hypertension, cholesterol, diabetes, overweight), which itself depends on chronic viral infections of the small intestine.

Chronic fermentation caused by poor nutrition and poor absorption of sugars leads to the production of polyamines (tumor growth factors), deficiencies (vitamin D, polyphenols) and a biofilm, which produces permeability and harmful microcurrents. The result is a strong immune alteration that changes from a beneficial TH1 status to a TH17 status, tolerating viral infections and cancers.
