The etiology of breast cancer might be explained by 2 mechanisms, namely, differentiation and proliferation of breast epithelial cells mediated by hormonal factors. We performed a systematic review and meta-analysis to update effects of risk factors for both mechanisms. MEDLINE and EMBASE were searched up to January 2011. Studies that assessed association between oral contraceptives (OC), hormonal replacement therapy (HRT), diabetes mellitus (DM), or breastfeeding and breast cancer were…

A systematic review and meta-analysis of case-control and prospective cohort studies showed a protective effect of ever breastfeeding against hormone receptor-negative breast cancers, which are more common in younger women and generally have a poorer prognosis than other subtypes of breast cancer.
Breast cancer risk factors in Iran: a systematic review & meta-analysis
This study suggests that factors such as family history, HRT, passive smokers, late full-term pregnancy, abortion, sweets consumption and genotype Arg/Arg might increase risk of breast cancer development, whereas late menarche, nulliparity, 13–24 months breastfeeding, daily exercise and vegetable consumption had an inverse association with Breast cancer development.
Association of oral contraceptives use and lung cancer risk among women: an updated meta-analysis based on cohort and case-control studies.
This meta-analysis suggests that OC use is not likely to be associated with the risk of lung cancer at all and more attention should be paid to the possible association of OC use with adenocarcinoma of lung.
A retrospective study on breast cancer presentation, risk factors, and protective factors in patients with a positive family history of breast cancer
Patients with a histologically confirmed breast cancer were divided into two groups: patients with and without a positive family history of breast cancer, and there was no significant difference in the incidence of Breast cancer among Malays, Chinese, and Indians.

This study provides evidence that ever breastfeeding, particularly a longer duration of breastfeeding, is associated with a lower risk of endometrial cancer.
TaqI polymorphism of VDR gene contributes to breast cancer risk
It is suggested that the VDR TaqI polymorphism confers risk effect on the breast cancer development, particularly in Caucasians, and no significant relationship was observed among Asians.
Hormone Use is Associated with Lymphovascular Invasion in Breast Cancer.
Hormone use, but not breastfeeding, was significantly associated, on multivariate analysis, with the prognostic variable lymphovascular invasion, connected to a worse prognosis, while no other hormone use or breast feeding correlations with prognostic variables were found.
Evaluation of Common Risk Factors for Breast Carcinoma in Females: a Hospital Based Study in Karachi, Pakistan.
Most of the well-known risk factors for breast cancer are also associated with the disease in the female population of Karachi, Pakistan.
Polymorphisms in the MTHFR gene are associated with breast cancer risk and prognosis in a Chinese population
Findings suggest that variants in the MTHFR gene may influence the risk and prognosis of breast cancer.


Diabetes mellitus and risk of breast cancer: A meta‐analysis
A meta‐analysis of case–control and cohort studies indicates that diabetes is associated with an increased risk of breast cancer.
Estrogen therapy and risk of breast cancer in postmenopausal women: a case-control study and results of a multivariate analysis
The results show that the risk of common exposure to both OCs and HT increases in women with other risk factors, however, several parameters traditionally considered in epidemiological studies do not have the same weight in each local community, suggesting the need to create different models to correctly select the high-risk population.
Selected medical conditions and risk of breast cancer.
While most examined conditions seemed unrelated to breast cancer risk, the association with late-onset diabetes is of special interest as it suggests a role of hyperinsulinaemia and insulin resistance in breast cancer promotion and points to preventive lifestyle modifications.
Factors Modifying the Association Between Hormone-Replacement Therapy and Breast Cancer Risk
Long-term HRT use was associated with a breast cancer risk in women with natural menopause and the findings suggest that this risk may be increased inWomen with a positive family history of breast cancer and in women who received frequent diagnostic mammographic screens.
Risk factors for breast cancer in Turkish women with early pregnancies and long-lasting lactation--a case-control study.
A hospital-based case-control study was carried out among 504 women with breast cancer and 610 controls to analyse the risk factors for breast cancer in Turkey, finding long-term lactation, oral contraceptive use, positive family history and menstrual irregularity to be key risk factors.
Hormone therapy and breast cancer: what factors modify the association?
The risk of breast cancer for recent users of HT in this Australian population is increased by approximately 50%, and any potential modifying effect of the association between HT and breast cancer risk by factors such as alcohol intake and body mass index is likely to be modest.
Risk Factors for Hormone Receptor-Defined Breast Cancer in Postmenopausal Women
Other risk factors were similarly related to breast cancer regardless of receptor status, but high age at first birth, substantial weight gain in adult age, and use of menopausal estrogen-progestin therapy were more strongly related to receptor-positive breast cancer than receptor-negative breast cancer.
Hormonal exposures and breast cancer in a sample of women with systemic lupus erythematosus.
The data suggest that the breast cancer experience in this sample is not completely explained by factors such as reproductive and family history, or by exogenous hormonal exposures, and other determinants, including medication exposures or genetic factors may be important.
Relationship between Menopausal Hormone Therapy and Risk of Ductal, Lobular, and Ductal-Lobular Breast Carcinomas
Although lobular carcinomas are less common than ductal carcinomas, this duration is shorter than the 5 years of use widely cited to be needed to confer an increased risk of breast cancer overall, and further studies focusing on the etiology of lobular cancer are needed.
