Following the Analysis of health records over 10 years of 580,000 patients researchers found that the overall risk is double for people with the highest blood pressure levels, compared to those with the lowest. While, it increases up to fourfold for people with meningioma and high blood pressure. The most common tumors that were diagnosed during the study were meningioma and glioma.
However, the experts did not have any data whether the participants were taking any medication for treating hypertension which could have affected the results. Therefore, they have cautioned that more examination is required before they can definitively say that high blood pressure increases the risk of brain tumors. The study was published in the Journal of Hypertension.
