The exact causes of gliomas are not known. Hereditary genetic disorders such as neurofibromatoses (type 1 and type 2) and tuberous sclerosis complex are known to predispose to their development.
Study suggests exercise during adolescence may cut risk of gliomas in adulthood.
HealthDay (10/6, Thomas) reported, "Exercising during adolescence may help guard against" gliomas "in adulthood," according to a study published Nov. 1 in the journal Cancer Research. Researchers "examined data on nearly 500,000 men and women aged 50 to 71" who responded to "questionnaires on height and weight at various points during their lives." They found that participants "who'd reported doing substantial amounts of light, moderate, and vigorous exercise between the ages 15 and 18 were 36 percent less likely to develop glioma than those who were sedentary." The study also showed that "those who were obese during their teen years had a three to four times greater risk of developing glioma than those of a normal weight." Notably, "tall people were also at increased risk of glioma," with "each 10 centimeter...increase" linked to "a nearly 20 percent increase in risk of developing glioma."
