Laryngeal cancer, childhood is a rare form of cancer found in children that is characterized by abnormal cell growth in the larynx, or voice box. Cancerous cells in the voice box can lead to impairment in speaking. Additionally, abnormal cell growth in the voice box can easily spread to other parts of the body. Individuals with this disorder may experience symptoms such as breathing problems, fatigue, and higher frequency of illness. This condition can be diagnosed with a physical exam, imaging tests, and a biopsy, which is where a part of the tissue is removed to be looked at under a microscope. Treatment depends on the stage of the cancer. If the cancer has progressed, doctors may suggest patients undergo chemotherapy or radiotherapy to destroy cancerous larynx cells.
