The prognosis (the probability of recovery) depends on many elements including:

• The type and the grade of the tumor at the moment of the diagnosis and at the moment of the treatment;
• The possibility to remove the tumor and its location;
• Whether cancer cells remain after surgery;
• Whether there are certain changes in the chromosomes;
• Whether the cancer has just been diagnosed or has recurred (come back);
• The patient’s general health.

The prognosis for metastatic brain tumors depend on the following:

• Whether the patient is younger than 60 years;
• Whether there are more than two tumors in the brain or spinal cord;
• The location of the tumor and its response to the treatment;
• Whether the primary tumor continues to grow or spread.
