Malfunctioning of Immune System May Increase Risk of Lung Cancer

The deadly disease of lung cancer is not only present among smokers but is also posing a threat to non-smokers as well. The most vital factor that works to save patients from lung cancer is its early detection. The early lung cancer is detected; the more are the chances for survival. A recent study has suggested that an immune system that is not functioning normally may lead to lung cancer among non-smoking patients. The study provides an insight about increasing rate of lung cancer in non-smokers.

Hung is a senior researcher at the Lunenfeld – Tanenbaum Research Institute at Sinai Health in Toronto, Canada. She said, “Our research suggests that the underlying dysfunction of immune regulation can lead to lung cancer, as if a shield is down.” In this study, the team of researchers looked at genes of 80,000 people to see if other conditions can cause lung cancer. No less than 70% of patients also have existing COPD or airflow obstruction. The co-author said that a strong immune system helps to keep inflammation under control and chronic inflammation promotes cancer.

The recent findings work to provide more insight into why lung cancer occurs in non-smokers. This also highlights the importance of immune regulations. Screening for CT scans can work to find the disease of lung cancer before appearing of its symptoms. The recent research findings increase the number of people to be screened so that the disease could be detected at an early stage. It lays importance on immune regulation. The report was published online in the journal Nature Communications.
