Ken & Milton,
There is a Vancouver, Canada firm [QLT Photodynamic Therapy of which I am a
small stockholder and not getting rich] which produces photofrins. This is a
delivery system in which very potent drugs are injected ito the body. The
drugs are inertt until activated by light. With cancer of the esophagus,
radiation therapy is not very effective and surgery is horrendous.. The
anti-cancer drugs are injected. A laser is run down the throat. Cancer cells
are hit with the laser and the drug is turned on only where the light hits,
leaving the healthy tissue undamaged.. Neat trick! CAUTION: DO NOT GO INTO
SUNLIGHT OR A BRIGHTLY LITT ROOM. No tanning salons!
