Brain cancer facts

  • Brain cancer can arise from many different types of brain cells (primary brain cancer) or occur when cancer cells from another part of the body spread (metastasize) to the brain. True brain cancers are those that arise in the brain itself.
  • Grades of brain cancers indicate how aggressive the cancer is.
  • Type of brain cancer indicates what kind of brain cells that gave rise to the tumor.
  • Staging of brain cancers indicates the extent of spread of the cancer.
  • Causes of brain cancer are difficult to prove; avoiding compounds linked to cancer production is advised.
  • Brain cancer symptoms vary but often include
  • Other common brain cancer symptoms are
    • nausea;
    • vomiting;
    • blurry vision;
    • a change in a person's alertness, mental capacity, memory, speech, or personality;
    • some patients may hallucinate.
  • Diagnostic tests for brain cancer involve a history, physical exam, and usually a CT or MRI brain imaging procedure; sometimes a brain tissue biopsy is done.
  • Treatments usually are directed by a team of doctors and are designed for the individual patient; treatments may include surgery, radiotherapy, or chemotherapy, often in combination.
  • Side effects of treatments range from mild to severe, and patients need to discuss plans with their treatment team members to clearly understand potential side effects and their prognosis (outcomes).
  • Depending on the brain cancer type and overall health status of the patient, brain cancer frequently has only a fair to poor prognosis; children have a somewhat better prognosis.
