There is No Evidence of side effects of HIFU – Fibroid and Prostate Treatment

HIFU is a new type of cancer treatment using a machine that gives off high frequency sound waves, which deliver a strong beam to a specific part of a cancer.Some cells die when this high intensity ultrasound beam is focused directly onto them, without harming surrounding structures.

It is commercially available only for a few applications, namely uterine fibroid treatment (the sole FDA approved device) and prostate treatment. A lot of work is currently done for developing this technique to treat other organs, especially the liver.

Small tumours can generally be destroyed in one session, but large tumours may require more than one session. There are advantages in some cases to combine HIFU with other medical treatments. It is normal to follow up the HIFU treatment with one or more MRI scans to confirm the destruction of the tumour.There is no evidence of side effects of diagnostic ultrasound. With HIFU there have been occasions when the skin has been affected by the equivalent of a mild sunburn, which clears up in a matter of days.

HIFU treatment can stimulate the immune system. In some treated patients, tumours that were not directly targeted have become smaller, and even disappeared. There is also evidence from Europe, where HIFU is being used to treat prostate cancer, of a similar immune response.
To be treatable with HIFU a tumour must be "lumpy" and in a position where it is visible using imaging ultrasound. There must be a clear path for the HIFU through to the tumour. Cancers near the surface of the skin are not treated, owing to the danger of skin damage. A decision on whether or not a tumour is treatable will be made before treatment commences.

HIFU, which is short for High Intensity Focused Ultrasound, is a state-of-the-art technology acoustic ablation technique that utilizes the power of ultrasound to destroy deep-seated tissue with pinpoint accuracy for treatment of prostate cancer. HIFU focuses sound waves in a targeted area which rapidly increases the temperature in the focal zone causing tissue destruction.

 In most cases, HIFU is a 1-4 hour, one-time procedure performed on an out-patient basis under spinal anesthesia. Unlike radiation, HIFU is non-ionizing; this means that HIFU may also be used as a salvage technique if other prostate cancer treatments fail.

 HIFU is an outpatient procedure general performed under local or general anesthesia that is completely radiation free. Because HIFU is non surgical, there is no incisions or blood loss and recovery is quick. HIFU therapy can be repeated, if necessary. It can also be used as a salvage therapy if other prostate cancer treatment options fail. Because it uses clean, ultrasound energy it doesn't cause harm to any tissue surrounding the targeted focal point.
