Introduction
Under normal circumstances, the lungs are the main respiratory organs of the human body, located within the thoracic cavity on either side of the mediastinum, one on the left and one on the right. The lungs are primarily situated below the clavicles, above the diaphragm of the abdomen, and on both sides of the sternum in the upper part of the body. Separated by the mediastinum, the lungs are divided into the left and right lungs, each covering the heart. The left lung is relatively narrow and elongated, and is divided by an oblique fissure into two lobes: the upper lobe and the lower lobe.

Under normal circumstances, the lungs are the primary respiratory organs of the human body, located within the thoracic cavity on either side of the mediastinum, with one lung on the left and one on the right. If any discomfort occurs, it is advisable to seek medical attention promptly. The detailed explanation is as follows:

The lungs are mainly situated below the clavicles and above the diaphragm of the abdomen, occupying the upper part of the body on both sides of the sternum. Divided by the mediastinum, the lungs consist of the left and right lungs, one on each side, covering the surface of the heart. The left lung is relatively narrow and longer, divided by an oblique fissure into two lobes—the upper and lower lobes—and is positioned slightly toward the left thoracic cavity, adjacent medially to the heart. In contrast, the right lung is slightly larger in volume than the left and is divided by both the oblique and horizontal fissures into three lobes: the upper, middle, and lower lobes. Medially, the right lung is adjacent to structures within the mediastinum, such as the esophagus and trachea.

In daily life, it is recommended to maintain fresh indoor air and avoid prolonged stays in areas with severe air pollution, such as industrial zones or heavily trafficked streets, to protect lung health.

Can lung cancer be detected through a routine blood test?
In general, routine blood tests cannot directly detect lung cancer. Blood tests can only reflect changes in indicators such as red blood cells, white blood cells, and platelets, but are unable to identify lung cancer cells or determine the presence of tumors in the lungs. If symptoms related to lung cancer—such as persistent cough or hemoptysis—are present, targeted examinations like chest CT should be performed promptly to avoid diagnostic delays caused by overreliance on routine blood tests.
