D02: Carcinoma in situ of middle ear and respiratory system
D02.1: Carcinoma in situ: Trachea
The tissue in the body is made up of cells. Cancer causes the cells to change, resulting in them multiplying uncontrollably. This leads to a malignant neoplasm (abnormal growth of tissue) developing. This abnormal and excessive tissue growth is called cancer. In your case, the cancer is limited to the skin or mucous membranes. This means that the cancer is very superficial and has not currently extended beyond a certain limit in the tissue. This also means the cancer has not yet been able to spread to other organs. However, the cancer cells can destroy the healthy tissue.
You often don’t get any symptoms with this early form of cancer.
You have an early form of cancer in the inner lining (mucous membrane) of your trachea. The trachea or windpipe begins below the larynx. It consists of many cartilage rings that strengthen the trachea. The trachea splits into 2 large airways in the middle of the chest. The airways then go into the lungs and branch out further.
