Big­ger brains linked to higher can­cer risk: Study

The Gulf Today - - WORLD -

LON­DON: Hav­ing a big­ger brain is di­rectly as­so­ci­ated with higher risk of brain can­cer, says a new re­search.

The study ex­plored that a larger brain con­sists of more brain cells, which leads to more cell divi­sion that can go wrong and cre­ate mu­ta­tions re­sult­ing in the in­creased risk of can­cer.

“Ag­gres­sive brain can­cer is a rare type of can­cer, but once you have it, the chance of sur­vival is rel­a­tively low,” said Even Hovig Fyllin­gen, a post­doc­toral stu­dent from the Nor­we­gian Univer­sity of Sci­ence and Tech­nol­ogy.

“Sev­eral stud­ies have shown that the size of dif­fer­ent or­gans is an im­por­tant fac­tor in can­cer de­vel­op­ment. Women with larger breasts have a greater risk of breast can­cer. We wanted to check if this was also the case for brain tu­mours,” said Fyllin­gen.

For the study, pub­lished in the jour­nal, Neuro-on­col­ogy, the team from the var­sity used MRI scans to mea­sure the size of the brain of 124 pa­tients.

Then 3D mod­els were made from them so that the in­tracra­nial brain vol­ume could be mea­sured in millil­itres.

THE in­d­ings of THE study RE­VEALED that women with big brains have a greater risk of de­vel­op­ing brain tu­mours com­pared to men with big brains.

“Men have a larger brain than women be­cause men’s bod­ies are gen­er­ally larger. It doesn’t mean that men are smarter, but you need to have more brain cells to con­trol a large body,” said Fyllin­gen.
