Search the PubMed database using various combinations of the following keywords: "Stress", "Psychological stress", "Life event", and "Breast cancer or breast cancer, cancer or cancer". The search interval is not limited. All published articles have no deadline and will be filtered based on titles and summaries. Next, we will obtain potentially eligible studies in full text and verify that we meet selection criteria and exclusion criteria. References lists of these articles were also reviewed to identify studies that were not first discovered or missed. In order to assess the quality of the methodology of the study, each paper is influenced by a Downs and Black control list [13].
Selection criteria: Case control, cohort study, or randomization study for women over the age of 18 diagnosed with a prospective study of primary breast cancer Follow up at least 5 years for quantitative or in English in Romanian Semi-quantitative pressure measurement method is included or French
Exclusion criteria: Analysis of stress caused by lifestyle, work environment or post traumatic stress disorder. This study analyzed the stress of women with medical psychosis history. Research shows the role of stress in the recurrence or prognosis of breast cancer. This study included treatment as a stress factor. Studies include the use of non-traditional therapies (massage, reflexology, acupuncture, mindfulness) to relieve stress. Comment, meta-analysis, editorial
Women who participated in the study were divided into two groups: the control group (n = 17), the women were diagnosed with breast cancer and there was no history of chronic mental stress; the stress group (n = 17) In the past when women were diagnosed with breast cancer, there is a history of chronic psychological stress. Formalin fixation from tumor biopsy, paraffin embedded sample, primary antibody against estrogen receptor (ER; anti-human estrogen receptor α, 1: 600 clone 1D5, Dako, Dinamarca), progesterone receptor (PR; anti human progesterone) Were immunostained. Dako, Dinamarca) using a commercially available immunohistochemical reagent; Dako, Dinamarca) and human epidermal growth receptor 2 (HER - 2, anti - human HER2 - pY - 1248, 1: 500 clone PN2A; Dako, Dinamarca ) Cloning box If at least 10% of the tumor nuclei are stained, the sample is considered ER / PR positive
When a doctor diagnoses breast cancer, it looks for three receptors expressed in breast cancer - estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) -. These are the causes of most breast cancer growth. They are also the usual goal of our physician in the treatment of breast cancer. However, some breast cancer patients lack these receptors. When this occurs breast cancer is called triple negative. And, without any receptors, the treatment can be more challenging. That is why Triple Negative Breast Cancer (TNBC) is one of the ones we care about as part of the Moon Shots program to significantly reduce cancer deaths.
Breast cancer is the most common cancer among women in the United States and around the world. Approximately 250,000 breast cancers are diagnosed every year in the United States, and about 40,000 have died 1. Obesity has been shown to be associated with increased risk of breast cancer morbidity and mortality. A rapid rise in obesity rates in the United States and around the world may affect the effort to lower breast cancer incidence and improve prognosis. In this article, evidence supporting the relationship between obesity and breast cancer incidence and prognosis, review of weight loss intervention studies in breast cancer population, and predictions of ongoing trials to evaluate the effect of intentional weight loss on breast cancer outcome We will consider.
