Coffee and tea lovers may have a decreased likelihood of developing the most common form of malignant brain tumor in adults, a new study suggests. And even if coffee and tea have some direct effect on glioma risk, the impact would be small. Brain tumors in general are uncommon; in Europe, for instance, annual rates are estimated at between four and six cases per 100,000 women, and six to eight cases for every 100,000 men. The findings, come from an ongoing study in 10 European countries investigating potential risk factors for cancer. At the outset, 521,488 men and women between the ages of 25 and 70 completed detailed questionnaires on their medical history, diet, exercise habits, smoking and other lifestyle factors.
