High-intensity ultrasound may launch attack on cancer, wherever it lurks
...r, several treatment options -- including surgery, radiation
or HIFU -- can be used to get rid of the cancerous tissues. However, if the cancer cells spread to other vital organs such as the lung or brain, the outcomes are often much worse. HIFU in the current form can only be used to treat the primary tumor...
