Large pulmonary nodules often form in the respiratory organs of both smokers and non-smokers.
A radiologist and professor at the University of Groningen (Netherlands) Rosemarin Vliegenthart shared a comment on this topic.
He said tests had been done which showed that lung nodules formed in about 11.1% of people.
And this does not depend on the presence or absence of tobacco dependence, according to the website of the Radiological Society of North America (RSNA).
Vliegenthart added that the risks increase significantly in people over 45 years of age.
The scientists made their conclusions based on health data from 10,000 people. The volunteers either never smoked or had given up the habit.
The study aimed to analyze biological markers that are associated with the development of a number of chronic diseases (coronary heart disease, lung cancer, COPD, etc.).
Over the entire observation period, 0.3% of subjects who had pulmonary nodules were diagnosed with lung cancer.
Scientists concluded that in the vast majority of cases, almost all large nodes in the respiratory system were benign in nature.
