Introduction: The breast cancer burden is still increasing, both in developing and developed countries. The present study was conducted to determine the survival rate of breast cancer based on tumor biological subtypes in patients referring to three referral oncology centers at Mashhad University of Medical Sciences, Mashhad, Iran.Methods: The present population-based study was conducted at Imam Reza Hospital, Omid Hospital, and Reza Oncology Center, Mashhad University of Medical Sciences, Mashhad, Iran Demographic information, the status of biomarkers in immune-histochemical evaluation, clinical and pathological features of the tumor, type of therapy, recurrence, or death was recorded for each eligible patient.Results: In total, 247 patients were included in the study. The mean age of patients was 48.8 ± 1.3 years. The mean time of survival was 2.64±0.13 years. In detail, the survival rate from the first year to the fifth year was reported as 100%, 96%, 91%, 90%, and 89%, respectively. The survival rate of the luminal B subtype was higher than other subtypes but the difference was not significant (P=0.7). Only in terms of metastasis, there was a significant difference between the alive and dead patients (P=0.0001).Conclusion: Despite no significant relationship between biological markers, the breast cancer subtype, and its survival rate, the overall survival rate of the patients decreased lightly through five years. However, further studies are required to indicate more accurate data about the breast cancer survival rate in our region.

Air pollution consists of chemicals resulting from many human activities and natural resources, which can cause gene mutations. Almost, it is proven that air pollution contributes to lung cancer and its relationship with other cancers including bladder, cervical cancer, ovary, prostate, brain and breast cancer is suspected. Breast cancer is the most frequent cancer in women and the prominent cause of death among them all around the world. Poor prediction of risk factor leads to discovery of more reliable factors. Mammary tumors in animals that are generated by chemicals compounds, give possible mechanisms for effects of environmental pollutants. Therefore, the purpose of our study is to review the available literature for investigating the relation of ambient air pollution and breast cancer. Findings of our study highlight the possibility of increasing in occurrence of breast cancer, developing to invasive cancer and mortality in both premenopausal and postmenopausal women exposed to air pollution.

Studies have devoted relatively scant attention to male breast cancer compared with female breast cancer. Nevertheless, the incidence of male breast cancer has increased considerably in parallel manner with women. There is not comprehensive knowledge regarding the etiology of breast cancer in men. The environmental agents and genetic factors are proposed as the influential parameters in the pathogenesis of breast cancer. Invasive ductal carcinoma is the most frequent subtype of breast cancer in men and a palpable mass is the most common presentation. Breast masses might be identified at advanced stages of the disease, if undiagnosed, due to the lower prevalence and lack of awareness in men compared to women. There is not any large sample size trial or retrospective study regarding any specific treatment strategy; the routine treatments are based on existing data. In this review, we studied the risk factors, biological characteristics, and therapeutic strategies of breast cancer in men.
