What is the survival rate for brain cancer?
Brain cancer survival rates depend on various factors like the stage of the disease, the patient's age and overall health, and the effectiveness of treatment. For example, according to the American Cancer Society, the five-year relative survival rate for individuals diagnosed with malignant brain tumors (glioblastoma) is about 40% for those under 45 years old, but this rate decreases to approximately 15% for those aged 45 and older. However, these statistics can vary greatly depending on the specific type of brain cancer, the patient population, and advancements in treatment options over time.
