"Combination therapy results for reovirus in animals are particularly encouraging because they suggest that Reolysin can improve the anti-tumor activity of standard ch...

Scientists discover how body fights to control spread of cancer

Natural gut hormone offers hope for new obesity drug

...earch showing that people with benign PP-secreting tumours have elevated levels of the hormone and yet appear to show no adverse side-effects. "These people may have had high levels of PP for ten or fifteen years without showing side effects," he explains. "In that sense, they have provided us with a natur...

Using nature's most primitive anti-viral defense system to find new approaches to cancer research

...atfield, AICR's scientific adviser: "Metastasis of tumours (the spread of cancer cells around the body) is the cause of mortality in the majority of human cancers and it is a complex, multi-step process. Understanding the molecular mechanisms that underlie each stage is therefore an important goal for cance...
