Methods Women already enrolled in a multimodality screening study for patients at HR-BC (gene mutation carrier or >20% cumulative lifetime risk) were given a questionnaire to evaluate their use of CAM therapies, diet, and exercise before and after a diagnosis of HR-BC. Patients were also asked to complete the Short-Form 36, State-Trait Anxiety Inventory, and Beck Depression Inventory. Results A total of 134 (67%) subjects completed the survey from the original cohort. General characteristics included a median age of 46 years (range = 24-73 years), majority were White (91%), BRCA1/2 gene mutation carrier (49%), and prior diagnosis of breast and/or ovarian cancer (30%). Almost all of the patients reported a lifetime prevalence of any HB (97%) and CAM utilization (91%). Subjects also had a high lifetime utilization of exercise (83%), herbs and supplements(72%), and diet programs (58%). All of these HBs declined in utilization after diagnosis of HR-BC by as much as 30%. After diagnosis of a HR-BC, a personal history of breast and/or ovarian cancer was significantly correlated with increased use of CAM (odds ratio [OR] = 5.9, P less then .01), herbs and supplements (OR = 4.3, P less then .01), and diet program (OR = 4.4, P less then .01) in multivariate analysis. Conclusions HBs such as CAM, diet, and exercise are highly prevalent among women with HR-BC, and the utilization of HB decreases significantly after diagnosis of HR-BC.DNA methylation is highly sensitive to in utero perturbations and has an established role in both embryonic development and regulation of gene expression. The foetal genetic component has been previously shown to contribute significantly to the timing of birth, y
