While some research institutions have claimed to have discovered a genetic gene for lung cancer, so far there is no consensus in the academic community. Whether lung cancer has a genetic effect has been inconclusive.
The Japanese Cancer Research Society, which has followed more than 100,000 Japanese middle-aged and elderly people for close to 13 years, showed 791 cases of lung cancer in the survey sample. And when the two groups with immediate family members who had lung cancer patients and those who did not were compared, it was found that the former were twice as likely to develop lung cancer as the latter. Indeed, clinically, many lung cancer patients can be found to have a corresponding family history, and families with lung cancer patients have a significantly higher chance of other people in the family getting lung cancer, so it may seem to be closely related to genetic factors.
But we can’t ignore the fact that lung cancer patients live with their families, share a common living environment, consistent eating habits, coordinated work and rest, and breathe common air, including lung cancer-causing factors such as secondhand smoke, and the family predisposition to lung cancer is indeed obvious. Is there a genetic predisposition for lung cancer? Further research is needed.
