People with high blood pressure may be twice as likely to
develop a brain tumour, according to the Daily Mail. The
newspaper said a new study had found an association between the
two factors, although crucially it could not show that high
blood pressure actually caused the tumour to develop. The
research followed more than half a million Norwegian, Swedish
and Austrian people for an average of about 10 years, looking at
how several factors related to their risk of developing a brain
tumour. After dividing people into five bands according to their
blood pressure, the researchers found that people with the
highest 20% of blood pressure readings were between 45% and 84%
more likely to have a brain tumour. However, they found that
having high blood pressure while the heart is at rest was only
associated with an 18% risk increase once adjustments were made
to account for other factors, such as age, gender and smoking
status. After these adjustments, there was no increased risk for
people who had higher systolic bl
