These people have tumors all over their bodies. You can't inject them all. Some are tiny and yet undetected. Chemo is systemic. Radiation before a tumor spreads can work. I'm not saying they aren't seeing good results. But look at what it was about Direct that was different....Memory. Tumors beyond the site of the injection were eliminated. Future tumors were stopped. Tumor regression at the site of injection is not success. Regression at other site is success. Maybe they see that and she just couldn't or didn't say it.
