What does it mean to have a lesion in the lungs, and does it require treatment?

　　Lung lesions refer to abnormal areas or shadows detected during lung imaging examinations, which may represent various pathological conditions. If the lesion is old and asymptomatic, treatment is generally not required; however, if it is caused by inflammation or a tumor, timely treatment is necessary.

　　1. Old lesions: These lesions may be remnants from previous inflammatory or non-inflammatory diseases that have healed. Old lesions typically do not require specific treatment if there are no other symptoms or complications.

　　2. Inflammatory lesions: Usually caused by infection of the lungs by viruses, bacteria, or other pathogens, leading to an inflammatory response. Anti-infective treatment is generally required, and medications such as amoxicillin tablets, isoniazid tablets, and rifampin tablets may be used as directed by a physician.

　　3. Tumor lesions: These include both benign and malignant tumors. Benign tumors typically grow slowly and have minimal impact on surrounding tissues, while malignant tumors may grow rapidly and invade and destroy surrounding tissues. Regardless of whether they are benign or malignant, surgical removal is generally required. Malignant tumors may also require chemotherapy and radiotherapy.

　　Patients should also maintain healthy lifestyle and dietary habits in daily life to enhance immune function and promote recovery.
