Brain Stem Cancer is a rare form of cancer characterized by abnormal cell growth in the brain stem. Individuals with this disorder may grow harmful tumors in the brain that can impair brain function and spread to the rest of the body if not diagnosed and treated early. The brain stem is important for maintaining eye movements, muscle movements, and motor coordination. Brain stem cancer can thus cause individuals to be less capable of performing important movements, like walking and running. Some individuals may loss their ability to move certain parts of their body (paralysis). Without early diagnosis and treatment, prognosis for this condition can be severe. Treatment is developed on a case-by-case basis and depends on the specific needs of the patient. If an individual's cancer has progressed, doctors may suggest chemotherapy or surgery to combat cancer symptoms.
