Life expectancy depends on the real situation of the patient. The most common length of survival after diagnosis of glioblastoma is 12 to 15 months. With proper treatments, about 3% to 5% of people will survive longer than five years. But without treatments, patient will survive only 3 months.
Study found that a small number of patients who have glioblastoma live more than 10–20 years with proper medical treatments. Therefore, people may have relatively long life expectancies if they follow the proper treatments and have positive attitudes.
