People with mellow levels of education may be more potential to develop certain types of brain tumors , a raw study from Sweden suggest .
Researchers discover that women who fill in at least three years of university course were 23 percent more probable to explicate a type of cancerousbrain tumorcalled glioma , compared with women who only completed up to nine years of compulsory education and did not go to a university . And man who make out at least three years of university course were 19 percent more probable to originate the same eccentric of tumor , compare with men who did not go to a university .
Though the reason behind the liaison are not clear , " one potential explanation is that highly educated people may be more cognisant of symptom and try aesculapian care earlier , " and therefore are more potential to be diagnosed , state Amal Khanolkar , a enquiry familiar at the Institute of Child Health at the University College Londonand a conscientious objector - author of the study .

In the bailiwick , the investigator looked at data on more than 4.3 million people in Sweden who were a part of the Swedish Total Population Register . The researcher tracked the people for 17 years , beginning in 1993 , to see if they develop brain neoplasm during that time . They also collected entropy about the people’seducation grade , income , marital position and occupation .
During the 17 - year study , 5,735 human and 7,101 women develop brain tumors , concord to the findings , published today ( June 20 ) in theJournal of Epidemiology & Community Health .
In addition to the divergence between encephalon tumor ontogeny and training grade , the researchers also notice an association between brain tumour development and income . serviceman who had higher incomes were 14 percent more likely todevelop gliomaduring the report period , compare with gentleman’s gentleman with gloomy incomes , according to the study . However , the relationship between the risk of this eccentric of mentality tumor and income level was not found in women , the researchers said .
Moreover , the study found that men who work in managerial and professional roles were 20 percentage more likely to develop glioma , liken with those who work manual jobs . These man were also 50 percent more likely to grow acoustic neuroma , a type of noncancerous brain tumor that produce on the nerve that is used for hearing and remainder .
The researcher also found that women who complete at least three age of university courses were also 16 percentage more likely to develop a type of mostlynoncancerous brain tumor called meningioma , compared with women who did not go on to higher instruction .
The new findings are in line with previous research , which has also found a connexion between an increase endangerment of certain psyche tumor and higher socio - economic status , the researcher said .
However , the fresh study only shows a connection between sure types of brain tumour and sure divisor ; it does not show that these component forthwith cause genius neoplasm , the researchers said . While other lifestyle factors might have also played a role , the researchers did not have memory access to such info , they say .
The idea that education levels and brain tumors are linked is not exclusively new .
" It has been an’urban legend’among neurosurgeon that smart people are more likely to get brain tumour , " say Dr. Raj K. Narayan , the chair of neurosurgery at North Shore University Hospital in Manhasset , New York , who was not involved in the new study . " However , I am somewhat surprised to find that this may in reality be straight . " The chemical mechanism behind this link is still unknown , but it might be that having more mind cellular telephone or greater psyche activeness somehow increases a person ’s endangerment of brain tumors , he told Live Science .
