Sonodynamic therapy is a quack cancer treatment which claims to use ultrasound and light to enhance the cytotoxic effects of drugs described as "sonosensitizers." It has been tested in vitro and in animals, but the results are not considered compelling and it is rejected by both mainstream science and some woo-promoters alike.[1]

The promotion of sonodynamic therapy motivated an unprecedented initiative by health authorities in the UK to warn patients about bogus cancer treatments.[2]

It should not be confused with the entirely legitimate photodynamic therapyWikipedia's W.svg (PDT). No way were the inventors trying to capitalise on that when they named it, no sir.

A land of confusion[edit]

It's never a good sign when practitioners keep alternating between a wide set of science-sounding titles for the therapy itself (ranging from the utterly vague to the overly technical). Known aliases include:

  • Sonodynamic therapy
  • Activated therapy
  • Sono Photo Dynamic Therapy (SPDT)
  • Next Generation Photodynamic Therapy (NGPDT)
  • Ultrasound Activated PDT (UAPDT)


As with all truly ground-breaking discoveries suppressed by the cancer industry, the studies supporting this are in low impact factor journals, including journals specialising in alternative therapies.[3]

Promoters of the sonodynamics attempted to push their nonsense on Wikipedia.[4] Fortunately, the current revision on the subject is appropriately brief and critical.[5]
