They take into account about a third of all brain tumors, and hold the highest mortality and incidence rate among primary brain cancer patients, creating an urgent need for effective treatments. Certain antidepressants already in the market could lower the chance of gliomas, but there’s been little evidence to aid their use in individuals.
