The researchers are missing the boat altogether.They are witnessing a natural phenomena I've explained 25 yrs ago in Cell Death Signal Theory as reviewed by M.D.Anderson Cancer Center [see cancerfraudbadbiotech for details ], but because they are treating cancer as a disease and not the aggravated medical condition it is (dna damaged embryogensis/apoptosis )they can't recognize the responses they are seeing.I used my ow theory and avoided chemo/radiation in 1997 and have been cancer free ever since .How sad people have to die such horrible deaths because the cancer industry is based on making money and not saving lives
