NEW PHOTODYNAMIC CANCER WEAPON Virginia Tech researchers have developed a new way to destroy cancer cells that uses photodynamic therapy. They say it could provide more efficient and less invasive treatments for cancer and other diseases, such as age-related macular-degeneration. The researchers have developed new tri-metallic supra-molecules that can be positioned in exact parts of cancer cells and activated by a therapeutic wavelength at which light moves efficiently through tissue. Only when the light hits the supra-molecules do they become toxic to the cancer cells. Physicians now use a chemical that is exposed to light and activates oxygen in photodynamic therapy. In tumor cells, oxygen is depleted rapidly so those treatments can run out of oxygen and not kill the entire tumor. The new system doesn't need oxygen and the researchers can change the wavelength of light used to fine-tune the treatment. UPI, 12/02 Remember we are NOT Doctors and have NO medical training.
