Study warns: These bacteria may aid cancer development
A new study published this week in the journal "Cancer Discovery" shows that bacteria are present in the airways and lungs. It can increase the development and spread of cancer in the body.
Looking at tissue samples from 83 patients. Researchers have found that people with advanced cancer carry more microbes than people with early stage disease.
The principal researcher Dr. said. Leopoldo Segal, the lungs may contain small amounts of bacteria even in healthy people. And these bacteria enter through the nose or mouth.
And when patients have large amounts of certain types of bacteria, they are less likely to survive. Even in the early stages of lung cancer.
Specifically, the condition of the patients harboring the bacteria Violonella, Perfutella and Streptococcus was worse. They also showed signs of a weakened inflammatory immune response that may worsen their condition.
Despite the results, Segal said, the research did not prove that the bacteria themselves were responsible for the aggravation of the condition. And that cancer itself may make the lungs more receptive to receiving these bacteria. This prompted researchers to experiment with transferring the bacterium Violonella to mice with lung cancer and found that it speeds up bad infections. And they fuel tumor growth and shorten the survival time of mice.
This indicates that lung bacteria may modify the immune response in a way that affects the development of lung cancer. According to what was reported by "UBI" website.
