If the field of radiation includes the tummy - more especially the colon - then near may be a causal relationship. If this is not the nouns being irradiated I would suggest that the increase surrounded by flatulence may be due to stress, change surrounded by rest/sleep habits, renovate in diet, and correction in comings and goings.
I don't think your sisters entwine is due to the radiatherapy, it may just the things she is drinking. Some people bring diarrhea from the treatment but it usually is if the treatment is on the stomach or the colon. If she is on a different diet then she use to be that could be to blame.
