World NewsNo link with cell towers, kids' cancerChildren whose mothers lived close to a mobile phone tower while pregnant did not appear to be at any higher risk of cancer than children whose mothers lived farther away, a new study finds. British researchers analyzed 1,397 cancer cases in children up to age 4 from 1999 to 2001 in the United Kingdom. Using a national birth registry, they identified 5,588 similar children without cancer. Next, they compared how far the children's mothers lived from a cell phone tower and the stations' signal strengths. No significant differences were seen between the two groups. (AP)
