Early stage lung cancer patients generally do not affect the sexual life of couples after recovering from normalcy through surgical treatment. Lung cancer is a common malignant tumor of the respiratory system, which can be caused by a variety of factors such as heredity, gene mutation, smoking, environment and living habits. Early stage lesions are often limited and can be treated by radical surgical resection, after which radiotherapy, chemotherapy, targeted therapy and other therapies can be supplemented according to the condition. After surgery and other treatments, the prognosis is often good, with a five-year survival rate of about 70%. About half a month to a month after the operation, the wound can be repaired completely, and patients can resume normal life, so couples can have a normal sex life. However, it is necessary to pay attention to regular checkups, maintain good living habits, healthy diet, and do not overwork.
