C30-C39: Malignant neoplasms of respiratory and intrathoracic organs
The group of conditions referred to as malignant neoplasms of respiratory and intrathoracic organs primarily involves dangerous growths in your breathing and chest organs. These growths, or "neoplasms", are considered malignant because they are cancerous, meaning they can grow uncontrolled and possibly spread to other parts of the body. They mainly affect organs such as the lungs, trachea, bronchus, and other parts within the chest area. The causes of these conditions can vary but often involve exposure to harmful substances like tobacco smoke, air pollution, and certain chemicals or dust. Common symptoms may include persistent coughing, difficulty in breathing, unexplained weight loss, and recurring chest infections. These conditions can progressively worsen over time, especially if left untreated, causing severe damage to the affected organs and potentially spreading to other organs.
