Large study finds no cell phone mast link to cancer

British scientists who conducted the largest study yet into cell phone masts and childhood cancers say that living close to a mast does not increase the risk of a pregnant woman's baby developing cancer.
      
       In a study looking at almost 7,000 children and patterns of early childhood cancers across Britain, the researchers found that those who developed cancer before the age of five were no more likely to have been born close to a mast than their peers.
      
       "These results are reassuring," said Paul Elliot, director of the center for environment and health at Imperial College London, who worked on the study.
      
       "We found no pattern to suggest that the children of mums living near a base station during pregnancy had a greater risk of developing cancer than those who lived elsewhere."
      
       Use of cell phones has increased dramatically in recent years and questions have been raised about possible health effects, including whether they may be linked to brain tumors or other cancers.
      
       Opinion polls have also shown high levels of public concern about the potential risks of living near mobile phone mast.

But Elliot, whose study was published in the British Medical Journal on Wednesday, said his work would add to a body of scientific research which has found no links between cell phones and cancer.

Cisco pushes video conferencing

Cisco Systems (Thailand) aims to double its revenue from video conferencing business this year, following its parent company's acquisition of worldwide video-conferencing specialist Tandberg.

The acquisition completes Cisco's production portfolio and the total range of its markets, and provides capacity in the mid-range market, which demands room-based video conferencing systems.
