High blood pressure may increase tumour link

  • Comment

High blood pressure has been linked to an increased risk of brain tumour development.

Analysing the health records over 10 years of 580,000 patients in Sweden, Austria and Norway, experts behind the research said 20% of participants with the highest blood pressure were more than twice as likely to be diagnosed later in life with meningioma or malignant glioma compared with the 20% who had the lowest blood pressure.

National cancer registries were checked for details on brain tumours, and 1,312 tumours had been diagnosed among the study group.

The researchers, who published their findings in the Journal of Hypertension, said patients were on average aged 41 when the study began, and brain tumour diagnosis came at the typical age of 56.

High blood pressure affects about 12 million people in the UK, with up to six million more living with the condition but unaware of it, while about 9,000 brain tumours are diagnosed every year.

The experts, whose work was funded by the World Cancer Research Fund, cautioned that more examination is required before they can definitively say that high blood pressure increases the risk of brain tumours.
