This post raises more questions than answers for me. Although i did chuckle at how the same page has a link to a study showing that solid cancer tumors work to get extra oxygen so they end up more resistant to radiation which would seem to indicate that for some tumors, more oxygen would be a bad thing.

So does anyone here know if oral cancer tumors are "hypoxic at the center" . The article only mentions pancreatic and cervical cancer tumors and this treatment apparently only works for hypoxic center solid tumors.
Also, what is a non-solid tumor?
Inquiring minds want to know
