Only ten minutes on a mobile could trigger cancer, scientists believe

Mobile phones can take as little as ten minutes to trigger changes in the brain associated with cancer, scientists claimed yesterday.

They found even low levels of radiation from handsets interfere with the way brain cells divide. Cell division encourages the growth of tumours.

Although the researchers did not come up with evidence that mobile phone signals are harmful, the findings suggest they could be. Several major studies have also found no link between mobile use and brain tumours, nor a dramatic rise in cancer rates. But campaigners insist the discovery undermines official advice that the devices are safe.

The guidance is based on the assumption that the phones emit too little radiation to heat the brain dangerously.

However, the new study by the Weizmann Institute of Science in Israel suggests "nonthermal" radiation could pose a risk.

The Israeli scientists exposed human and rat cells in a laboratory to low-level radiation at 875 megahertz - a similar frequency to the one used in many mobile phones.

Although the radiation was far weaker than emissions from a typical handset, it began to switch on a chemical signal inside the cells within ten minutes, the researchers report in the Biochemical Journal.

The chemical signals they detected were involved in the division of cells.
