Despite the high rates of breast cancer among young Mexican women, their special needs and concerns have not been systematically addressed. To fulfill these unsatisfied demands, we have developed "Joven & Fuerte: Program for Young Women with Breast Cancer in Mexico," the first program dedicated to the care of young breast cancer patients in Latin America, which is taking place at the National Cancer Institute of Mexico and the two medical facilities of the Instituto Tecnológico y de Estudios Superiores de Monterrey...

BACKGROUND: Young women with breast cancer (YWBC) comprise a group of patients with unique biopsychosocial characteristics with a special perception of needs throughout their disease and survivorship. Contexts marked by restricted allocations and economic constraints might further aggravate the struggle of these patients living within limited resource settings and can demand added requirements for them and their families. OBJECTIVE: To analytically explore the existing knowledge regarding the needs of YWBC in low- and middle- income countries (LMICs)...

Young women with breast cancer have age-specific concerns regarding changes in sexuality, fertility, and body image. However, the psychological impact of BC and its treatments is not exclusive to young patients and it also affects their social context, especially their partners, as they experience higher illness intrusiveness than the partners of older women. In young BC patients, relationships, body image, and sexual problems are related to most quality of life domains. While BC treatment is being planned, all women should be informed about the possible side-effects of treatment on sexuality, fertility, and body image...

The incidence of breast cancer (BC) is rising worldwide, with an increase in aggressive neoplasias in young women. Traditionally, BC in young women has been thought to be etiologically driven, primarily by genetic/hereditary factors. However, these factors explain only a small proportion of BCs, pointing to a role of the environment. Suspected factors responsible for this increase include lifestyle changes, notably alcohol consumption, diet with high intake of refined carbohydrates and saturated fat and low intake of polyunsaturated fatty acids (PUFA), fiber and vitamins (such as folate, vitamin D, and carotenoids), low physical activity, and body fatness, all of which may act from childhood and adolescent years through adulthood...

Young women with breast cancer (YWBC) represent roughly 15% of breast cancer (BC) cases in Latin America and other developing regions. Breast tumors occurring at an early age are more aggressive and have an overall worse prognosis compared to breast tumors in postmenopausal women. The expression of relevant proliferation biomarkers such as endocrine receptors and human epidermal growth factor receptor 2 appears to be unique in YWBC. Moreover, histopathological, molecular, genetic, and genomic studies have shown that YWBC exhibit a higher frequency of aggressive subtypes, differential tumor gene expression, increased genetic susceptibility, and specific genomic signatures, compared to older women with BC...

Young women with breast cancer (BC) are a special population with distinctive genetic, clinical, and psychosocial features and requirements based on at least three considerations: (1) Cancer presentation at young age is often diagnosed at advanced stages, hence its prognosis is worse compared to their older counterparts1,2; (2) young BC patients often receive aggressive and prolonged systemic treatments that can be associated with significant long-term morbidity3; and (3) young women with BC experience substantial psychosocial vulnerability resulting from high levels of distress and depression associated with oncological interventions4...

There is ongoing debate concerning non-nutritive sweeteners, their usage, and their effects on metabolism. The association between non-nutritive sweeteners consumption, development of metabolic diseases, and changes in appetite-regulating hormones is not clear. The aim of this article is to present an overview of non-nutritive sweeteners and to examine the scientific evidence of their effects on glucose metabolism and appetite-regulating hormones. Some observational studies suggest an association between non-nutritive sweeteners consumption and development of metabolic diseases; however, adiposity is a confounder frequently found in these studies...

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...

Thanks to the improved survival outcomes observed in recent years, a growing attention has been given to the quality of life issues faced by young women with breast cancer such as fertility preservation and concerns related to future pregnancies. However, several challenges remain for young women with breast cancer considering undergoing fertility preservation strategies. Further specific issues on this regard should be taken into account in Latin America, where patients and physicians face particular barriers that hinder the routine adoption of this practice...

In Latin America, breast cancer is the most common malignancy in women, and limited available data suggest that up to 15% of all breast cancer cases in the region are hereditary. Genetic cancer risk assessment and counseling is a critical component of the appropriate clinical care of patients with hereditary breast cancer and their families. Unfortunately, genetic services are underdeveloped across Latin America, and access to genetic testing and counseling is very scarce in the region. Barriers contributing to the access to genetic care are high cost and lack of insurance coverage for genetic tests, insufficient oncogenetics training or expertise, nonexistence of genetic counseling as a clinical discipline, and lack of supportive healthcare policies...

Breast cancer in young women is a complex disease to manage due to its biological heterogeneity and special issues related to toxicity of different treatment strategies. Defining a cut-off for young age has been challenging since it is not clear whether the prognostic effect of age is continuously variable or whether there are certain thresholds at which the prognosis changes (e.g. those < 50 years of age or ≤ 35 years of age). In this review article, we define young patients as those being premenopausal...

In recent years, it has become evident that intra-tumor heterogeneity of breast cancer is a big challenge for the diagnosis, treatment, and clinical course of tumor-bearing patients. The advances in molecular biology and other technologies have led to the knowledge that a breast cancer tumor is comprised of multiple cellular entities. Here we review the two theories that have been described, trying to explain the origin of intra-tumor heterogeneity: clonal evolution and cancer stem cells. The first one considers that a single cell gives rise to many subpopulations through the accumulation of multiple aberrations, while the cancer stem cells theory foresees a hierarchical tumor evolution where only a few cells with self-renewal capacity give rise to different subpopulations...

Breast cancer is the most common malignant tumor among women of reproductive age and is also the most costly according to European reports. In this context, the aim of the present review is to identify factors that make breast cancer in premenopausal women an epidemiological challenge in developing countries. Epidemiological aspects of breast cancer, including risk factors, early detection methods, and treatment, are addressed. Breast cancer in premenopausal women should be included in the political and strategic agendas in developing countries to direct the necessary resources for prevention, detection, and control...

Breast cancer (BC) is the most frequently diagnosed malignancy in young women and is the leading cause of cancer-related mortality in this age group. This issue represents a major public health problem in developing countries, where the incidence of BC is rapidly increasing and where young women represent a higher proportion of the total BC patient population compared to developed countries. In Latin America, BC among women aged 40 years or less accounts for up to 11% of new BC cases and 7% of all BC deaths...
