What is it?
In a nutshell, Sonodynamic therapy is the use of low level ultrasound, along with naturally derived sensitizers, to produce tumor destruction, especially cavitations in malignant cells.
Is it effective?
The use of ultrasound allows deeper penetration for treatment of such tumors as those which may be located in the lungs and liver. Case studies, however, show equally effective results for breast cancer, prostate cancer, ovarian cancer, and skin originated cancers, such as melanoma and squamous cell carcinoma.
How long has this been used?
Therapies employing Sonodynamics have been around since the late 1800's, but their efficacy was limited by the marginal effect that available sensitizers (primarily chemotherapeutic agents) had on cancer cells. Even without effective sensitizers, the treatment showed merit in treating, particularly, shallow tumors.
What is new regarding this treatment?
In the late 1990's new, non-toxic agents were developed in Russia using, primarily, derivatives of Chlorphyll and algae. These sensitizers were far more effective, and in the intervening years, testing and treatment have shown great promise.
