Ok, bear with me, I am only an upset observer here, I know nothing about their methods, biology etc. But isn't prudent to get the cancer cells into some ecosystem or bioreactor, apply various factors and study them there instead of this Nazi like trial and error research involving those animals ? With the current state of technology one could imagine we should be able understand and see into these things well enough. They claim to be able to sequence much smaller DNA so why not 'sequence' or look into the cancer here. Also inside organisms they are able to highlight and target cancer with some agent and see exactly where the cancer cells are using that PET scanner technique, but unable to use the same path to deliver treatment to those areas. It seams to me that this cancer 'industry' is trying to do prolonged and expensive healing, but not to cure.
