If I quit smoking for one month after quitting for two years, will it increase my risk of lung cancer?

Whether relapse after quitting smoking for one month after two years of quitting will increase the risk of lung cancer depends on the specific situation. If you only relapse occasionally and do not experience other discomfort symptoms, it generally does not increase the risk of lung cancer. However, if you relapse frequently and have symptoms such as coughing and sputum, it may increase the risk of lung cancer.

1. No: Smoking is a common cause of lung cancer. Cigarettes contain a large amount of nicotine, carbon monoxide and other harmful substances, which will damage lung tissue after being inhaled into the lungs, thus inducing lung cancer. If the patient occasionally relapses during the period of quitting smoking and does not have obvious symptoms of discomfort, this will not lead to aggravation of the disease and increase the risk of lung cancer.

2. Yes: However, if you are in a secondhand smoke environment for a long time or smoke heavily frequently, it will cause serious irritation to your lungs and may even cause diseases such as bronchitis and pneumonia, which will increase the risk of lung cancer.

Patients are advised to go to the hospital for relevant examinations and treatment in time to avoid delaying the disease. In daily life, we should develop good living habits, avoid smoking, drinking and eating spicy and irritating foods, and eat more fresh fruits and vegetables, such as apples and tomatoes, which can supplement the vitamins needed by the body and are beneficial to health.
