Why do some lifelong smokers remain cancer-free?

It has long been a subject of scientific inquiry why some individuals remain free from lung cancer despite a lifetime of smoking. According to a report by ABP Ananda, research suggests that genetic factors and the body's inherent ability to repair cells play a critical role in this phenomenon. Studies indicate that some people possess a unique biological capacity to resist DNA mutations caused by smoking, which provides them with a level of protection against the development of cancer.
