Did you realize that approximately 10% of lung cancer patients have never in their lives smoked cigarettes? When asked about lung cancer prevention, most people will tell you that the easiest way to prevent lung cancer is to never take up the dangerous habit of cigarette smoking. And while its true that smoking often leads to lung cancer, the fact that 10% of lung cancer patients are not now nor have ever been smokers cannot be easily explained.

Cancer in its simplest definition is the potential end result of a mutation or alteration that occurs within a gene. And sometimes, there is just no way to stop (or prevent) a gene from changing, nor is there a way to control the genes you inherit. When one gene in particular, the epidermal growth factor receptor gene, undergoes a mutation, the mutation is such that it basically gives the green light for malignant cells to grow and also to divide. Such a situation is totally unavoidable.
