Metastatic seeding may be related to leakiness of tumor blood vessels, and factors dealing with dissolving the framework [matrix] around normal cells, so that cancer cells can get in and invade.
Bill’s Cocktail cannot prevent metastases from occurring. However, by preventing blood vessel growth to the tumors, it can deprive metastases of growth. So we would suspect that people on adequate doses of cocktail ingredients would get metastases, but the metastases cannot grow past a 2 mm size or so, because they cannot get blood vessels growing to them. In most areas of the body, a 2mm metastasis that is not growing is not easily found.
