A recent published study found that inhalation of harmful microbes can contribute to advanced stage lung cancer in adults. It is known that long-term use of face-masks may help breed dangerous pathogens and that frequent mask wearing creates a perfect, moist environment in which microbes proliferate before entering the lungs. The invading microbes travel down the trachea and the bronchi until they reach the tiny alveoli. The presence of these bacterial cultures is also associated with a lower chance of survival and increased tumour growth regardless of the stage.
