Scientist’s Study Reveals Hopes Smokers Avoid Lung Cancer

Jakarta, CNN Indonesia

Smoking is considered to be the main cause of lung cancer. But new findings from researchers may slightly reduce the truth of this assumption.

Launch Science Daily, cigarettes can trigger DNA mutations in the lungs of normal people. Mutations that over time make the lungs of smokers susceptible to cancer.

Experts from the Albert Einstein College of Medicine in the United States (US) have also experimented to prove it through a study.

The study was carried out by a research team using genetic profiles, which were obtained from heredity or under other conditions through engineering, taken from the bronchi of 14 smokers, who had never smoked, and 19 light, moderate and heavy smokers.

Experts found that cell mutations in the lungs of normal people progress more slowly than those of smokers. “The experiment confirmed that smoking increases lung cancer by increasing the frequency of mutations,” said Simon Spivack, one of the researchers involved in the study.

“That’s one of the reasons why so few people who don’t smoke get lung cancer. While 10 to 20 percent of long-time smokers are more at risk,” he added.

But in addition to these findings, experts also found unique facts. Cell mutations in the lungs turned out to depend on each individual.

The same goes for smokers. According to Spivack, there are some heavy smokers who can suppress the mutation of their cells.

In addition, the experts also found that cell mutations slowed down after 23 years of exposure to cigarettes.

“Our data suggest that these individuals may not develop lung cancer even if they are heavy smokers because they can suppress the accumulation of the mutation,” Spivack said.

“The slowing of the mutation could come from these people who have good systems at repairing DNA damage or neutralizing toxins from cigarette smoke,” he added.

Still Observing

Furthermore, experts are still researching why the ability to repair DNA is different in each individual. It is hoped that through this study, the individual’s risk of developing lung cancer can be better understood.

“We now hope to develop new research that measures a person’s capacity to repair DNA, which could offer a new way to assess a person’s risk of developing lung cancer,” said Jan Vijjg, who was also involved in the study. Science Alert.
