C14.2: Malignant neoplasm: Waldeyer ring

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 throat begins behind the mouth and nose. The throat connects the mouth and nose with the windpipe (trachea) and gullet (oesophagus).

In the throat there are tissues that are part of the immune system. The immune system protects the body from pathogens and foreign substances. The immune system can also destroy cells in the body that have pathologically changed. For example, the tonsils and the mucous membrane at the back of the throat form part of the immune system. Cells in your tonsils or the mucous membrane at the back of your throat have multiplied unchecked.
