It seems quite simple really....Ultrasound kills cancer cells quickly and effectively without damaging surrounding tissue. High intensity focused ultrasound heats the tumour above 60C for 2 seconds.
The tumour dies and is re-absorbed. No chemotherapy
no radiotherapy, no scalpel that allow cancerous cells escape and regrow in other parts of the body,
and no observed side effects.
More than 3000 patients at twenty centers have been treated in China. Plus almost 100 patients in Britain have been treated at the Institute of Cancer Research with ultra sound, all with positive
preliminary results.
Gail ter Haar told the American Association for the Advancement of Science conference in Seattle yesterday, that due to the rigorous clinical trials that have been conducted, early results are exciting
Nevetheless research remains at an early stage, and widespread clinical applications are probably 4 or 5 years away.
