Long-Term Mask Use May Contribute to Advanced Stage Lung Cancer, Study Finds
A recent study in the journal
Cancer Discovery found that inhalation of harmful microbes can
contribute to advanced stage lung cancer in adults. Long-term use of
face masks may help breed these dangerous pathogens.
Microbiologists agree that frequent mask wearing creates a moist environment in which microbes are allowed to grow
and proliferate before entering the lungs. Those foreign microbes then
travel down the trachea and into two tubes called the bronchi until they
reach small air sacks covered in blood vessels called alveoli.
"The lungs were long thought to
be sterile, but we now know that oral commensals–microbes normally
found in the mouth–frequently enter the lungs due to unconscious
aspirations.” – 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 invading the lungs these microbes cause an inflammatory response in proteins known as cytokine IL-17.
“Given the known impact of
IL-17 and inflammation on lung cancer, we were interested in determining
if the enrichment of oral commensals in the lungs could drive an
IL-17-type inflammation and influence lung cancer progression and
prognosis,” said Segal.
While analyzing lung microbes of 83 untreated adults with lung cancer, the research team discovered
that colonies of Veillonella, Prevotella, and Streptococcus bacteria,
which may be cultivated through prolonged mask wearing, are all found in
larger quantities in patients with advanced stage lung cancer than in
earlier stages. The presence of these bacterial cultures is also
associated with a lower chance of survival and increased tumor growth
regardless of the stage.
Additionally, research into the
cultivation of Veillonella bacteria in the lungs of mice found that the
presence of such bacteria leads to the emergence of immune suppressing
cells as well as inflammatory ones such as cytokine IL-17.
“Given the results of our
study, it is possible that changes to the lung microbiome could be used
as a biomarker to predict prognosis or to stratify patients for
treatment.” – Leopoldo Segal
As more evidence emerges pertaining
to the long-term effects of mask mandates and lock downs, doctors and
scientists are beginning to reconsider whether these authoritarian
measures really are doing more harm than good. One Canadian public
health expert named Dr. Aji Joffe found in a related study that lock downs cause “at least ten times” more damage than benefit.
In a recent working paper by researchers at Harvard, Duke, and John Hopkins Universities, academics concluded that “for
the overall population, the increase in the death rate following the
COVID-19 pandemic implies a staggering 0.89 and 1.37 million excess
deaths over the next 15 and 20 years, respectively.”
Since forced mask wearing began, dermatologists have coined the term ‘maskne’ to describe an onset of pimples near the mouth caused by masks clogging up pores with oil and bacteria. This can be caused by either disposable or cloth masks.
Dentists have also been warning about a phenomenon known as ‘mask mouth’
in which patients are arriving back to the dental office with an
increase in gingivitis and tooth decay as high as 50% in a period of
just a few months since mask mandates began.
This discovery sheds light on the growing evidence of harm caused by long-term mask wearing.
