Mobile phone masts might have been declared safe. But there is no knowing. Residents of housing complex in Bristol, England are panic-stricken after three cancer deaths since two masts were erected on the roof of the five-storey block.

Another four are battling the disease. The cancer rate on the top floor - where residents of five of the eight flats have been affected and the three who died all lived - is 20 per cent, ten times the national average.

Besides other residents complain of severe headaches. Cancer or headache, everything suffered by the residents is blamed on the radiation from the masts. The situation is so bad that the block is dubbed the Tower of Doom.

Orange, a service provider, has agreed to move its mast, but only after a five year campaign.

Orange has agreed to remove its mast after a five-year campaign by residents and pressure from the local authority. But it has caused anger with plans to move it to a residential street nearby.

The most recent death was that of John Llewellin, 63, who lost his battle against bowel cancer two weeks ago.

The other victims on the top floor are Hazel Frape, 63, who has had breast cancer, and 89-year-old Phyllis Smith who moved out after she contracted the same disease.

On the fourth floor Bernice Mitchell, 69, has battled womb cancer. On the second floor, 78-year-old Barbara Watts, who has lived in the block for 31 years, is in remission from breast cancer.
