If a cure for lung cancer were available, it would indeed eliminate the life-threatening risk associated with smoking. However, it's essential to remember that smoking has numerous adverse health effects beyond lung cancer. Smoking is a major cause of various diseases, including heart disease, respiratory conditions, and other types of cancer.
Quitting smoking or avoiding smoking altogether remains the best course of action to maintain good health and reduce the risk of many serious health issues. Even with a cure for lung cancer, smoking would still be detrimental to overall health and well-being. It's always wise to prioritize prevention and lead a healthy lifestyle rather than relying solely on potential future cures for diseases caused by unhealthy habits.
