Breast cancer is the most frequent cancer among women. Approximately one third of all cancers in women is breast cancer which has a high mortality rate and is second only to lung cancer in cancer related deaths in women. Unfortunately, during the past 50 years, the prevalence of breast cancer has been raised probably due to life style changes. Recently, the prevalence of this cancer...
background: oral contraceptive pills are among the most popular contraceptive methods, but the fear of cancer and cardiovascular disease overshadows its continuous use among women. this study aimed to define the association between consumption patterns of combined oral contraceptives among women with breast cancer. materials and methods: this is an analytical case–control study conducted on 175...
mri of the breast has evolved as a non-invasive imaging modality and is ideally suited for several indications e.g. pre-operative staging and screening in women at increased risk for breast cancer. the widespread use opens also the discussion on over-diagnosis if only 20 - 30 out of 100 mri - guided breast biopsies lead to the diagnosis of breast cancer. thus mri based strategies are needed to ...
Background and purpose: Breast cancer is the most common type of cancer among women. In radiation therapy for breast cancer it is important to prevent damage to normal tissues particularly to lung tissue. In this study, we investigated the incidence of damage in patients with breast cancer by clinical and dosimetric parameters to identify the predictive factors. Materials and methods: An exp...
background: polycystic ovary syndrome (pcos) is a heterogeneous complex genetic disorder characterized by hyperandrogenemia hyperinsulinemia insulin resistance and chronic anovulation. it is the most common endocrine disorder in women of reproductive age with an enigmatic pathophysiologic and molecular basis. obesity hyperandrogenism and infertility occur frequently in pcos which mostly have a ...
conclusions the findings of the meta-epidemiological study support that ebv infection may increase the risk of breast cancer. nested case-control studies are required in the future. results a total of 20 case-control studies were selected, and the total numbers of subjects in the case and control groups were 1947 and 1010, respectively. the findings of this meta-analysis revealed that ebv infec...

Breast cancer is the most common cancer worldwide and is the second leading cause of death in women after lung cancer. Micro RNAs (miRNAs) are among endogenous factors which are involved in many types of cancers, including breast cancer. Single nucleotide polymorphism (SNP) in the miRNAs, might change their biological activities such as their effects on oncogenes and tumor suppressor genes. The...
Introduction: Vitamin D fulfills its crucial role in cell proliferation and death through signal transduction into the nucleus by vitamin D receptor (VDR). Recent studies have depicted the association between VDR gene polymorphisms and different cancers, including breast cancer. This study attempted to consider the relationship between VDR gene polymorphisms and breast cancer risk among women i...
