Possible link between antibiotics and increasing speed of breast cancer growth There could be a possible link between antibiotic use and the speed of breast cancer growth, a study of mice suggests. Antibiotics are often prescribed to breast cancer patients undergoing chemotherapy to control infections during treatment. Researchers at the University of East Anglia (UEA) set out to research whether disruption of the healthy bacteria in the gut caused by antibiotic use would have an effect on tumour growth. The role of the gut microbiome has been examined in relation of several cancers.
