C78.2: Secondary malignant neoplasm of pleura

You have metastases in the membrane around your lungs.

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

The cancer cells have spread in your body and multiplied at another site. These are called metastases.

The lungs are on the left and right side of the ribcage. They are also connected to the nose and mouth via the bronchial tubes and windpipe (trachea). You need lungs to breath. When we breathe in, oxygen enters the lungs and accumulates in the blood. This blood then flows to the heart. The heart then pumps the oxygen-rich blood throughout the body. All of the organs are supplied with oxygen as a result. The lungs are surrounded by a smooth membrane. A smooth membrane like this is also located inside the ribs. Both membranes cling to each other via a small amount of fluid. Through the suction of the fluid between the membranes, the lungs follow the movements of the chest while breathing. The lungs then alternately expand and contract. Air for breathing flows into the lungs and out again during these movements.
