Exactly and that is what the Doctors are treating .I do not think Catherine is receiving heavy duty Chemotherapy and that may be why she is apparently having relatively minor side effects. I think when the BBC recorded the video she was very frightened but is now able to come to terms with her illness and treatment .She does of course need to be brave for her three children though it is clear that both George and Charlotte understand she is fragile at the moment .
