Women’s views about breast cancer prevention at mammography screening units and well women’s clinics

Background Women attending mammography screening units (msus) and well women’s clinics (wwcs) represent a motivated cohort likely to engage in interventions aimed at primary breast cancer (bca) prevention. Methods We used a feasibility questionnaire distributed to women (40–49 or 50–74 years of age) attending msus and wwcs in Halifax, Nova Scotia, to examine ■ women’s views about bca primary prevention and sources of health care information, ■ prevalence of lifestyle-related bca risk factors, and ■ predictors of prior mammography encounters within provincial screening guidelines. Variables examined included personal profiling, comorbidities, prior mammography uptake, lifestyle behaviours, socioeconomic status, health information sources, and willingness to discuss or implement lifestyle modifications, or endocrine therapy, or both. A logistic regression analysis examined associations with prior mammography encounters. Results Of the 244 responses obtained during 1.5 months from women aged 40–49 years (n = 75) and 50–74 years (n = 169), 56% and 75% respectively sought or would prefer to receive health information from within, as opposed to outside, health care. Lifestyle-related bca risk factors were prevalent, and most women were willing to discuss or implement lifestyle modifications (93%) or endocrine therapy (67%). Of the two age groups, 49% and 93% respectively had previously undergone mammography within guidelines. Increasing age and marital status (single, separated, or divorced vs. married or partnered) were independent predictors of prior mammography encounters within guidelines for women 40–49 years of age; no independent predictors were observed in the older age group. Conclusions Women attending msus and wwcs seem to largely adhere to mammography guidelines and appear motivated to engage in bca primary prevention strategies, including lifestyle modifications and endocrine therapy. Women’s views as observed in this study provide a rationale for the potential incorporation of bca risk assessment within the “mammogram point of care” to engage motivated women in bca primary prevention strategies

U–Pb chronology of the Ennerdale and Eskdale intrusions supports sub-volcanic relationships with the Borrowdale Volcanic Group (Ordovician, English Lake District)

U-Pb analyses of zircons from the Ennerdale granitic intrusion and Eskdale Granite (English Lake District) give ages of 452 ± 4 Ma and 450 ± 3 Ma respectively. These data confirm the sub-volcanic association of these intrusions, and show that previously published Rb–Sr whole-rock and K–Ar mineral ages do not correspond to the emplacement and cooling of these igneous bodies. The new ages show that only two phases of acid magmatism can now be linked to the exposed parts of the Lake District batholith. The Caradoc (late Ordovician) phase was caused by the subductionrelated processes which gave rise to volcanism, and was followed by a separate early Devonian phase of granite emplacement
