Lung diseases are a diverse group of disorders that affect the lungs. Common lung diseases include asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and lung cancer. These conditions can impact the ability to breathe properly, leading to symptoms such as coughing, wheezing, shortness of breath, and chest pain. Lung diseases can be caused by smoking, infections, environmental factors, genetic predisposition, or other underlying health conditions. Treatment options for lung diseases vary depending on the specific condition but may include medications, respiratory therapies, lifestyle changes, and in severe cases, surgery. Early detection and proper management of lung diseases are crucial for improving outcomes and quality of life for affected individuals.
