Sonophotodynamic therapy (SPDT) is the modern form of same. There are some 50 publications SPDT based on results in China, England, Australia and Mexico.
We use laser activation at 660-680 nanometers because Sp-Activate (photosensitizer) is best activated in that range.
Similarly we use the sound at 2.3 megahertz and ------. From experience we find SP-Activate (photosensitizer) is best activated is this way.
We have specific information on the toxicology, pharmacology and the industrial development of this product from its raw state to its final purified condition. This information is the property of the Hope4Cancer Institute. It is important to note that are literally no side-effects apart from some tiredness after treatment. There is none of the photo-sensitivity of the older agents. This compares very favorably with side-effects from e.g. various other prostate cancer therapies.
How PDT works:
Step 1 - The patient ingests a photosensitizer (PS),
Step 2 - The PS is selectively absorbed by cancer cells.
Step 3 - Exposure to light activates the PS, producing a high-energy molecule PS*.
This in turn gives up the energy it has acquired in two ways:
- By reacting with oxygen in the body to produce free radical oxygen and other free radicals. These are powerful oxidants, so powerful that they immediately attack nearby organic material - the cancer cell.
- 2. By emitting fluorescent radiation that can be detected and used to locate cells that have taken up the PS, once again - the cancer cells.
