C30: Malignant neoplasm of nasal cavity and middle ear
C30.0: Malignant neoplasm: Nasal cavity
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.
We need the nose for breathing and smelling. The outside of the nose is composed of bone and cartilage. The nasal septum divides the nasal cavity into two halves. The inside of the nose is lined with a moist mucous membrane. The nasal concha are bony protrusions in the nose, and also lined with mucous membrane.
The cells in your nose have multiplied uncontrollably.
