A recent study in the journal Cancer Discovery found that inhaling harmful microbes may contribute to advanced-stage lung cancer in adults. Long-term use of face masks may contribute to the proliferation of these dangerous pathogens.
Microbiologists agree that frequent mask-wearing creates a moist environment where microbes can grow and multiply before entering the lungs. These foreign microbes then travel down the trachea and into two tubes called bronchi until they reach small air sacs covered with blood vessels called alveoli.
“The lungs have long been considered sterile, but we now know that oral commensals – microbes that normally reside in the mouth – often enter the lungs through unknowing aspiration.” – Leopoldo Segal, study author and director of the Lung Microbiome Program and associate professor of medicine at New York University Grossman School of Medicine.
According to the study, after entering the lungs, these microbes cause an inflammatory response in proteins known as cytokine IL-17.
“Given the known effects of IL-17 and inflammation on lung cancer, we were interested in determining whether the accumulation of oral commensals in the lung could drive IL-17-type inflammation and impact lung cancer progression and prognosis,” Segal said.
Analyzing the lung microbiota of 83 untreated adults with lung cancer, the research team discovered that colonies of Veillonella, Prevotella, and Streptococcus bacteria, which may be cultured by prolonged mask wear, are present in greater amounts in patients with advanced-stage lung cancer than in earlier stages. The presence of these bacterial cultures is also associated with lower survival and increased tumor growth, regardless of stage.

In addition, studies on the cultivation of Veillonella bacteria in the lungs of mice have shown that the presence of such bacteria leads to the development of immune suppressive as well as inflammatory cells such as the cytokine IL-17.
“Given the results of our study, it is possible that changes in the lung microbiome could be used as biomarkers to predict prognosis or stratify patients for treatment.” – Leopoldo Segal
As more evidence emerges about the long-term effects of mandatory masks and lockdowns, doctors and scientists are beginning to rethink whether these authoritarian measures really do more good than harm. A Canadian health expert named Dr. Aji Joffe found in a related study that lockdowns do “at least ten times” more harm than good.
In a recent working paper by researchers at Harvard, Duke, and John Hopkins Universities, the scientists concluded that “for the population as a whole, the increase in mortality following the COVID-19 pandemic translates into staggering numbers of 0.89 and 1.37 million additional deaths over the next 15 and 20 years, respectively.”
Since the beginning of forced mask wearing, dermatologists have coined the term “maskne” to describe the appearance of pimples near the mouth caused by masks clogging pores with oil and bacteria. This can be caused by both disposable and cloth masks.
Dentists have also warned of a phenomenon known as “mask mouth”, where patients come to the dentist’s office with an increase in gingivitis and tooth decay of up to 50 % within a few months since the mask requirement began.
