In 2007, the International Agency for Research on Cancer declared shift work involving circadian disruption to be a "probable" carcinogen (group 2A), noting that human evidence was limited. This study examined associations between rotating night shift work and breast cancer risk in two prospective cohorts, the Nurses' Health Studies (NHS: 1988-2012, n = 78,516; NHS2: 1989-2013, n = 114,559), with 9,541 incident invasive breast malignancies and 24 years of follow-up. Women in NHS with 30+ years of shift work had no increased risk of breast cancer (Hazard ratio (HR) = 0...

BACKGROUND: Exposure to endogenous hormones such as estrogen is known as a lifetime Breast Cancer (BC) risk factor. Polymorphisms in genes that are involved in the steroidogenic process, such as Cytochrome P450c17alpha (CYP17), affect individuals' susceptibility to BC. In Iran, the highest incident of BC is among young women. This study aimed to find prevalence of Single Nucleotide Polymorphisms (SNPs) in genes such as CYP17 and significant correlation with age-oriented group of breast cancer...

Breast cancer (BC) in Oman affects younger women and has a more aggressive course. Clinical and biological variables like age, pregnancy, tumor size, type, grade, receptor expression and proliferation predict disease aggression but there is no direct predictor of metastasis except lymphovascular invasion. Epithelial-mesenchymal transition (EMT) is characterized by epithelial cells losing epithelial and acquiring mesenchymal morpho-immunophenotypic characteristics. In tumors, EMT-like transitions may signify a metastatic phenotype and have features in common with cancer stem cells (CSC) which show resistance to chemotherapy...

BACKGROUND: Fertility and pregnancy issues are of key importance for young breast cancer patients. Despite several advances in the field, there are still multiple unmet needs and barriers in discussing and dealing with these concerns. To address the significant challenges related to fertility and pregnancy issues, the PREgnancy and FERtility (PREFER) study was developed as a national comprehensive program aiming to optimize care and improve knowledge around these topics. METHODS: The PREFER study is a prospective cohort study conducted across several Italian institution affiliated with the Gruppo Italiano Mammella (GIM) group evaluating patterns of care and clinical outcomes of young breast cancer patients dealing with fertility and pregnancy issues...

Although much research has examined the experience of breast cancer, the distinctive perspectives and lives of young women have been relatively neglected. Women diagnosed with breast cancer under the age of 45, and who had completed their initial treatment, were interviewed, and social constructionist grounded theory methods were used to analyse the data. The end of initial treatment was accompanied by a sense of unease and uncertainty in relation to recurrence and survival, and also fertility and menopausal status...

PURPOSE: Although breast cancer in young women accounts for <10% of diagnoses annually, tumors in young patients exhibit more aggressive characteristics and higher mortality rates. Determination of the frequency of germline mutations in cancer predisposition genes is needed to improve the understanding of breast cancer etiology in young women. METHODS: All female patients enrolled in the Clinical Breast Cancer Project between 2001 and 2015 and diagnosed with invasive breast cancer before age 40 were included in this study...

The objective of this study was to explore the factors that influence perceived personal risk of developing breast cancer (BC) in younger women (<35) who are considering or have undergone bilateral prophylactic mastectomy (BPM). Qualitative interviews guided by interpretative phenomenological analysis were conducted with 46 women who had a strong family history of BC and had either undergone (n = 26) or were considering (n = 20) BPM. Participants were recruited from Australia and New Zealand via hospitals, a genetics clinic, a research cohort, a registry and online...

The purpose of this study was to investigate the relationship between ABO blood types and breast cancer survival in young Korean patients. This was a retrospective study of 115,474 patients who were surgically treated for primary breast cancer between 1987 and 2011 in Korea. All data were collected by the Korean Breast Cancer Society (KBCS) online breast cancer registry. Each hospital serologically examined the ABO blood types of patients before surgery. There was no significant difference in overall survival (OS) or breast cancer-specific survival (BCSS) among ABO blood types...

REVIEW
S F Lax
Hereditary breast and ovarian carcinomas are frequently caused by germline mutations of the BRCA1 and BRCA2 genes (BRCA1/2 syndromes) and are often less associated with other hereditary syndromes such as Li-Fraumeni and Peutz-Jeghers. The BRCA1/2 proteins have a special role in DNA repair. Therefore, loss of function due to mutation causes an accumulation of mutations in other genes and subsequent tumorigenesis at an early age. BRCA1/2 mutations are irregularly distributed over the length of the genes without hot spots, although special mutations are known...

BACKGROUND: Skin cancer has reached epidemic proportions, with more new cases diagnosed annually than the combined incidence of cancers of the breast, prostate, lung, and colon. Estimates show 2 to 3 million new cases of non-melanoma skin cancer (NMSC) every year, and, among women, it is the young (younger than 45 years) who are disproportionately affected. OBJECTIVE: This article aims to address questions and concerns pertinent to skin cancer in a woman-centric way...

Breast cancer among Palestinian women has lower incidence than in Europe or North America, yet is very frequently familial. We studied genetic causes of this familial clustering in a consecutive hospital-based series of 875 Palestinian patients with invasive breast cancer, including 453 women with diagnosis by age 40, or with breast or ovarian cancer in a mother, sister, grandmother or aunt ("discovery series"); and 422 women diagnosed after age 40 and with negative family history ("older-onset sporadic patient series")...

BACKGROUND: The tAnGo trial was designed to investigate the potential role of gemcitabine when added to anthracycline and taxane-containing adjuvant chemotherapy for early breast cancer. When this study was developed, gemcitabine had shown significant activity in metastatic breast cancer, and there was evidence of a favourable interaction with paclitaxel. METHODS: tAnGo was an international, open-label, randomised, phase 3 superiority trial that enrolled women aged 18 years or older with newly diagnosed, early-stage breast cancer who had a definite indication for chemotherapy, any nodal status, any hormone receptor status, Eastern Cooperative Oncology Group performance status of 0-1, and adequate bone marrow, hepatic, and renal function...

In the USA and other countries, oocyte donation is gaining increasing importance. Although sufficient data exist on procedure-associated short-term risks for oocyte donors, such as ovarian hyperstimulation syndrome, long-term follow-up studies of egg donors are lacking and their health risks are unknown. The lack of information may be misleadingly interpreted as lack of risk. Long-term hormone replacement therapy is recognized as a risk factor for breast cancer; the breast cancer risk of ovarian stimulation for egg donors is unknown but is a possibility...

BACKGROUND: Women younger than 45 years old have lower rates of breast cancer, but higher risk of recurrence and mortality after a cancer diagnosis. African American women are at risk for early onset and increased mortality; Ashkenazi Jewish women are at risk for genetic mutations leading to breast and ovarian cancer. Although younger women are encouraged to talk to doctors about their family history, little is known about these discussions. MATERIALS AND METHODS: In 2015, 167 women aged 18-44 years participated in 20 focus groups segmented by geographic location, age, race/ethnicity, and family history of breast and ovarian cancer...

PURPOSE: Breast cancer (BC) diagnosis in young adults (YA) is rising, and both disease and treatments are aggressive in this population. Evidence supports the use of physical activity in reducing shoulder dysfunction, which is common among BC survivors. A pilot randomized clinical trial was performed to determine the effectiveness of a 12-week post-radiation exercise program in minimizing upper extremity dysfunction in YA with BC. METHODS: Participants were randomized to either an exercise arm or a control arm receiving standard care...

BACKGROUND: Younger breast cancer survivors face a unique set of treatment-related issues that have enormous impact on quality of life and psychological well-being. Although there is often a profound and distressing impact of treatment on self-image and sexual function, women rarely receive any attention for these issues. Unfortunately, most clinicians receive no training on how to inquire about these problems and most clinicians feel unprepared to discuss them. Often this silence is due to a lack of ready resources and uncertainty of appropriate strategies for rehabilitation...
