Finding cancers early allows for more effective treatment with the least side effects, so finding better ways to detect cancers is an important part of the fight. A new technique may help us “hear” where cancers are, allowing doctors to diagnose cancers more precisely than is currently possible. The technique, which is called photoacoustic tomography, takes pictures of sound waves that come from tissues when laser light is shined on the tissue. This is possible because different parts of the body absorb different amounts of light. When light is absorbed, it raises the temperature of the tissue, and the temperature More >
