The harmful substances present in tobacco smoke, such as carcinogens and toxic chemicals, can cause DNA damage and genetic mutations, leading to the development of lung cancer. By quitting smoking, individuals allow their bodies to gradually repair and restore the damaged lung tissue, reducing the risk of cancer initiation and progression. Over time, the lung's natural defense mechanisms regain their function, improving lung health and reducing the likelihood of cancerous transformation. Moreover, smoking cessation has been shown to have a positive impact on precancerous lung lesions, known as lung dysplasia. Studies have demonstrated that quitting smoking can lead to a regression of these lesions, further reducing the risk of Non-Small Cell Lung Cancer development.
