Washington: Physical activity during adolescence may help guard against a deadly form of brain tumour in adulthood, says a new study.Although very less is known about the causes of glioma, researchers at the National Cancer Institute have found that this rare but often deadly form of brain cancer may be linked to early life physical activity and height.
Participants who were physically active during adolescence had a decreased risk of glioma; their risk was about 36 percent lower than those who were inactive, according to the study. The researchers also found that those who were obese during adolescence had an increased risk of glioma; their risk was approximately three to four times that of individuals who were normal weight during adolescence. However, Moore cautioned that "we did not have many people in the study who were obese during adolescence." ANI
