Diet is the primary source of cadmium - a proven Group 1 human carcinogen - for non-smokers. Observational studies investigating the effect of cadmium from food sources on breast cancer risk have produced inconsistent results. We examined the association between dietary cadmium and risk of breast cancer defined by estrogen receptor (ER), progesterone receptor (PR) and HER2 status, in 8,924 women recruited to a prospective study between 1987 and 1992. Dietary cadmium intake was estimated using a semi-quantitative food frequency questionnaire at baseline...

Within the last years significant improvements have been achieved in early and metastatic breast cancer treatment by innovative targeted therapies and new drug combinations. GnRH-analogues have been confirmed as an important part of endocrine treatment in premenopausal patients. Endocrine based strategies including CDK-4/6-Inhibitors substantially improve progression-free survival in metastatic patients. For patients with HER2-positive disease the addition of Pertuzumab to Trastuzumab in combination with chemotherapy has achieved a significant improvement in anti-HER2 therapy in early as well as metastatic breast cancer...

BACKGROUND: Several studies conducted in developed countries introduced diet and physical inactivity as major risk factors for several types of cancers. However, the impact of diet and physical inactivity on the risk of breast cancer (BC) is understudied, and the limited findings are controversial. In addition, no or limited knowledge is available from the developing world. PATIENTS AND METHODS: This case-control study was performed from November 2014 to March 2016 on 1010 young women aged 20 to 50 years who were newly diagnosed with BC...

The constitutional t(11;22)(q23;q11) translocation is the only recurrent non-Robertsonian translocation known in humans. Carriers are phenotypically normal and are usually referred for cytogenetic testing because of multiple miscarriages, infertility, or having aneuploidy in offspring. A breast cancer predisposition has been suggested, but previous studies have been small and had methodological shortcomings. We therefore conducted a long-term prospective study of cancer and mortality risk in carriers. We followed 65 male and 101 female carriers of t(11;22)(q23;q11) diagnosed in cytogenetic laboratories in Britain during 1976-2005 for cancer and deaths for an average of 21...

Genitourinary syndrome of menopause (GSM), encompassing the disorders of atrophic vaginitis, urinary incontinence, and pelvic prolapse, affects the majority of postmenopausal women, as well as patients who are undergoing breast cancer treatement, post-ovarectomy, post-radiation, and breast-feeding. There is a need for better treatment options for these common conditions that adversely affect physical function and quality of life and that are often underserved by existing options. Lasers have been used to treat genitourinary tissue for over 40 years, and over the past decade, several lasers and radiofrequency devices have been developed and clinically tested for the treatment of GSM, with an accumulating body of evidence demonstrating their safety and efficacy...

PURPOSE: Mammographic density is a strong risk factor for breast cancer. Although diet is associated with breast cancer risk, there are limited studies linking adult diet, including milk intake, with mammographic density. Here, we investigate the association of milk intake with mammographic density in premenopausal women. METHODS: We analyzed data from 375 cancer-free premenopausal women who had routine screening mammography at Washington University School of Medicine, St...

BACKGROUND: Patients with cartilage-hair hypoplasia (CHH), a rare metaphyseal chondrodysplasia, manifest severe growth failure, variable immunodeficiency and increased risk of malignancies. The impact of CHH on gynecologic and reproductive health is unknown. Vulnerability to genital infections may predispose CHH patients to prolonged human papillomavirus (HPV) infections potentially leading to cervical, vaginal and vulvar cancer. METHODS: We carried out gynecologic evaluation, pelvic ultrasound and laboratory assessment in 19 women with genetically confirmed CHH...

Women at increased breast cancer (BC) risk are eligible for chemoprevention. Healthy lifestyles are potentially important for these women to improve efficacy and minimise side effects of chemoprevention and reduce the risk of BC and other lifestyle-related conditions. We investigated whether women taking chemoprevention adhere to healthy lifestyle recommendations, how their lifestyle risk factors and health measures compare to women in the general population, and whether these change whilst taking chemoprevention...

BACKGROUND: Trastuzumab (Herceptin® - H) has been the standard-of-care for patients with HER2+ breast cancer (BC) since 2009 in the Czech Republic. Neoadjuvant application of H increases the number of patients who achieve pathological complete remission (pCR) and improves patients' outcomes. AIM: This study aimed to assess the effect of neoadjuvant therapy (NAT) with H in patients with early HER2+ BC and to correlate the therapeutic outcome with overall survival (OS)...

The agonistic/antagonistic biocharacter of selective estrogen receptor modulators (SERMs) can have therapeutic advantages, particularly in the case of premenopausal breast cancers. Although the contradictory effects of these modulators have been studied in terms of crosstalk between the estrogen receptor α (ER) and coactivator dynamics and growth factor signaling, the molecular basis of these mechanisms is still obscure. We identify a series of regulatory mechanisms controlling cofactor dynamics on ER and SERM function, whose activities require F-box protein 22 (Fbxo22)...

Clinical studies provide strong evidence that obesity and associated adipose tissue (AT) inflammation are risk factors for breast cancer (BrCA); however, mechanistic knowledge of the interaction of obesity, BrCA, and menopausal status has proven to be not only lacking, but contradictory. Obesity-induced inflammation and elevated biosynthesis of estrogens, through aromatase-mediated metabolism of precursors, have been linked with hormone receptor positive (HP) postmenopausal BrCA but not previously associated with premenopausal BrCA risk...
