There is a lack of evidence‐based recommendations for the age at which women with a family history of cancers other than breast cancer should start breast cancer screening. METHODS Using Swedish family cancer data sets, the authors conducted a nationwide cohort study including 5,099,172 Swedish women born after 1931 (follow‐up, 1958‐2015). Accounting for calendar time,… Continue reading Risk‐adapted starting age of #breast cancer screening in women with a family history of #ovarian or other cancers: A nationwide cohort study

Association of #PET-based #estradiol-challenge test for #breast cancer progesterone receptors with response to endocrine therapy
Estrogen receptor (ER) testing of breast cancer imperfectly predicts response to endocrine therapy (ET). We hypothesize that a brief estradiol challenge will increase tumor progesterone receptor (PgR) levels only in tumors with functional ER. In this prospective, phase 2, single-center, single-arm trial (NCT02455453), we report the association of response to ET with change in tumor… Continue reading Association of #PET-based #estradiol-challenge test for #breast cancer progesterone receptors with response to endocrine therapy
#Antibiotic exposure during pregnancy and childhood #asthma: a national birth cohort study investigating timing of exposure and mode of delivery
...A total of 5522 (17%) children were born to mothers exposed to antibiotics during pregnancy. In adjusted analyses, children born to exposed mothers had higher odds of asthma (OR 1.14, 95% CI 1.05 to 1.24). There was no association with antibiotic exposure in the first trimester (OR 1.02, 95% CI 0.83 to 1.26), but higher… Continue reading #Antibiotic exposure during pregnancy and childhood #asthma: a national birth cohort study investigating timing of exposure and mode of delivery
Incorporating Baseline Breast #Density When Screening Women at Average Risk for #Breast Cancer
..Intervention: No screening; biennial or triennial mammography from age 50 to 75 years; annual mammography from age 50 to 75 years for women with dense breasts at age 50 years and biennial or triennial mammography from age 50 to 75 years for those without dense breasts at age 50 years; and annual mammography at age… Continue reading Incorporating Baseline Breast #Density When Screening Women at Average Risk for #Breast Cancer
#Ovarian cancer risk in relation to blood #lipid levels and hyperlipidemia: a systematic review and meta-analysis of observational epidemiologic studies
Epidemiologic evidence regarding association of ovarian cancer risk with blood lipid level and hyperlipidemia is inconsistent. We aimed to synthesize available epidemiologic studies to disentangle associations of cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and hyperlipidemia with ovarian cancer risk. We searched PubMed, EMBASE, and Web of Science for eligible studies. A… Continue reading #Ovarian cancer risk in relation to blood #lipid levels and hyperlipidemia: a systematic review and meta-analysis of observational epidemiologic studies
Individualizing Surveillance #Mammography for Older Patients After Treatment for Early-Stage #Breast Cancer Multidisciplinary Expert Panel and International Society of Geriatric Oncology Consensus Statement
..After a literature review of the risk of ipsilateral and contralateral breast cancer events among breast cancer survivors and the harms and benefits associated with mammography, a multidisciplinary expert panel was convened to develop consensus guidelines on surveillance mammography for breast cancer survivors 75 years or older. Using an iterative consensus-based approach, input from clinician… Continue reading Individualizing Surveillance #Mammography for Older Patients After Treatment for Early-Stage #Breast Cancer Multidisciplinary Expert Panel and International Society of Geriatric Oncology Consensus Statement
2021 The Effect of Preconception-Initiated Low-Dose #Aspirin on Human Chorionic Gonadotropin–Detected Pregnancy, #Pregnancy Loss, and Live Birth
A previous large randomized trial indicated that preconception-initiated low-dose aspirin (LDA) therapy did not have a positive effect on pregnancy outcomes. However, this trial was subject to nonadherence, which was not taken into account by the intention-to-treat approach.. ..Relative to placebo, adhering to LDA for 5 of 7 days per week led to 8 more… Continue reading 2021 The Effect of Preconception-Initiated Low-Dose #Aspirin on Human Chorionic Gonadotropin–Detected Pregnancy, #Pregnancy Loss, and Live Birth
#Benzophenone-3 promotion of mammary tumorigenesis is diet-dependent
Benzophenone-3 is a putative endocrine disrupting chemical and common ingredient in sunscreens. The potential of endocrine disrupting chemicals to act as agonists or antagonists in critical hormonally regulated processes, such as mammary gland development and mammary tumorigenesis, demands evaluation of its potential in promoting breast cancer. This study identifies the effects of BP-3 on mammary… Continue reading #Benzophenone-3 promotion of mammary tumorigenesis is diet-dependent
RANK links #thymic regulatory T cells to fetal loss and gestational #diabetes in pregnancy
Successful pregnancies rely on adaptations within the mother1, including marked changes within the immune system2. It has long been known that the thymus, the central lymphoid organ, changes markedly during pregnancy3. However, the molecular basis and importance of this process remain largely obscure. Here we show that the osteoclast differentiation receptor RANK4,5 couples female sex… Continue reading RANK links #thymic regulatory T cells to fetal loss and gestational #diabetes in pregnancy
