Phone signal can cause cancer, especially cancer? Indeed the signal spreads out radiation, but can it triggers any cancer risk in human body? A study by scientists in Japan has lain to rest these fears by finding that mobile use does not increase the risk of brain tumours. The tumours that were analysed for in this study were meningioma – the most common benign tumour, glioma - a type of primary central nervous system (CNS) tumour, and pituitary adenoma - tumours that occur in the pituitary gland.

As a part of the study, scientists at Tokyo Women’s Medical University led by Dr N Yamaguchi compared phone use in 322 brain cancer patients with 683 healthy people. The case group consisted of newly diagnosed 132 meningioma patients, 88 glioma patients, and 102 pituitary adenoma patients between the ages of 30-69 years treated in participating hospitals, with case recruitment performed prospectively from December 2000 to November 2004.

Use of the Personal Handy-phone System (PHS), a type of cordless telephone system, was also recorded. Demographic variables, medical history, and occupational history were also recorded. Clinical information on the cases was obtained from the relevant department.

Based on their research, the boffins stated that they had found no association between mobile phone use and cancer, providing more evidence to suggest they don’t cause brain cancer. The findings of the study are published in the British Journal of Cancer.
