Breast cancer treatment may be less likely for people who periodically diet, a new study has found.
Scientists discovered that mice with intermittent calorie restriction experienced nine per cent incidence of cancer tumour, whereas those with a chronically restricted calorie intake experienced 25 per cent cancer growth.
Those mice that were able to eat as much as they wished experienced 71 per cent mammary tumour, the report, which is published in Cancer Prevention Research, found.
Dr Margot Cleary, professor at the Hormel Institute, University of Minnesota, commented: "Understanding how calorie restriction provides protection against the development of mammary tumors should help us identify pathways that could be targeted for chemoprevention studies.
"Further identification of serum factors that are involved in tumor development would possibly provide a way to identify at risk individuals and target interventions to these people."
