As a result of the cytogenetic and statistical evaluation, the number of damaged cells, chromosomal aberrations, and expression frequencies of fragile sites detected in patients with breast cancer and their first-degree relatives were found to be significantly higher than those in the control group. Our findings indicate an increased genetic instability in women with breast carcinomas and their relatives. Therefore, fragile sites may be used as a reliable marker for defining genetic susceptibility to cancer in general.eninfo:eu-repo/semantics/closedAccessOncologyGenetics & heredityToxicologyBreast cancerAphidicolinCaffeineFragile sitesGenetic susceptibilityChromosomal abnormalitiesLung cancersChromosome breakpointsAphidicolinLymphocytesArticle0000786422000022-s2.0-003246342327929118610052563OncologyGenetics & heredityToxicology
