The prognosis of brain cancer depends on the type of cancer and its location. The age, health of the individual, and whether the tumor can be treated or surgically removed also determine the prognosis.
Research has shown that the survival rate beyond five years for individuals with primary brain cancer varies between 10 and 32 percent even with surgery, chemotherapy and radiation therapy. Treatment does help to prolong survival in the short term and may also improve the quality of life.
Individuals with secondary brain cancer may be at risk due to the primary cancer itself. Radiation therapy and chemotherapy helps to increase life expectancy. Those who experience seizures tend to have a poor prognosis over the following 6 to 7 months.
