Minimally invasive surgery for lung cancer generally does not affect sexual function, but for patients with poor recovery of lung function, it will affect sexual function to some extent. Lung cancer is a tumor originating from the bronchial mucosa or glands in the lungs, which is a malignant tumor. Once diagnosed with lung cancer, it can be treated with surgery, including open-heart surgery and thoracoscopic surgery. Thoracoscopic surgery itself will not cause adverse effect on the sexual function of lung cancer patients, and if patients recover well after surgery, they can have normal sexual life. However, if lung cancer patients are in serious condition, or minimally invasive surgery does not achieve better curative effect, resulting in poor recovery of lung function and poor physical condition, sexual function will be affected to some extent. For lung cancer patients, they need to have sexual life after surgery according to their recovery. If the body recovery is poor, premature sexual life is not recommended. They should rest more and avoid overwork. Meanwhile, regular review should be conducted to avoid recurrence of the disease, so as to achieve early detection and early treatment and improve prognosis.
