Cambridge Study Reveals Why Some Smokers Avoid Lung Cancer

A new study from the University of Cambridge has identified genetic factors that explain why some long-term smokers do not develop lung cancer, while some non-smokers do.

Researchers found that specific DNA repair mechanisms in certain individuals effectively mitigate the damage caused by smoking and UV radiation, preventing tumor formation.

These findings provide direct evidence that genetic background plays a critical role in cancer evolution, potentially opening new avenues for personalized cancer prevention strategies.
