Fresh fears over the health hazards linked to using mobile phones have been raised after scientists found that handset radiation could trigger cell division, it was revealed here Thursday.
A study found the exposure to mobile phone signals for just five minutes stimulated human cells to split in two, a process that occurs naturally when tissue grows or rejuvenates, but that is also central to the development of cancer, The Daily Telegraph newspaper said.
Previous research on the safety of mobile use has led to conflicting conclusions, with some suggesting links with tumours in the nervous system and others finding no risks.
The six-year Mobile Telecommunications and Health Research Programme is expected to present its final report next month, the paper added.
Official guidance that mobile phones were safe was based on the mainstream scientific assumption that electromagnetic radiation from such devices would damage cells and tissue only by heating them.
But the new research, reported in this week's "New Scientist" magazine, supported the position of those researchers who argue that handsets can trigger potentially harmful changes to cells irrespective of temperature changes.
After just five minutes the researchers identified the production of natural chemicals that stimulate cell division and growth.
Cancers develop when the body is unable to prevent excessive growth and division of cells in the wrong place.
