Very interesting paper:
"Chemotherapy and radiotherapy, whilst highly effective in the treatment of neoplasia, can also cause damage to healthy tissue. In particular, the alimentary tract may be badly affected. Severe inflammation, lesioning and ulceration can occur."
"Th disruption or loss of rapidly dividing epithelial progenitor cells is a trigger for the onset of the disorder."
"Severe inflammation, lesioning, ulceration and bleeding can occur in the mouth, esophagus, and intestine."
"...ability to absorb nutrients much reduced..."
Hummmm, I wonder what 11 years of chemo-compound drugs will do to the intestinal tract? These were short term results done on cancer patients.
