Breast cancer is the most frequent malignancy in women worldwide. The purpose of this study was to investigate some established risk factors for breast cancer in women aged 22 to 63 in Urmia.

A case-control study was conducted  to investigate risk factors for breast cancer among women in Urmia. Data were collecctd through interviews with175 breast cancer patients and 172 control women during 2016 to 2018.

The results of univariate logistic regression analysis havee shown Single women (OR 1.253, 95% CI 0.587-2.671) and women with a primary level of education wereat high risk for breast cancer (OR 2.87, 95% CI 1.383-5.986). multivariate logistic regression model indicated that high BMI (OR 1.1, 95% CI 1–1.21) and an increasing  number of pregnancies (OR 3.04, 95% CI 1.37–6.74) were significantly associated with breast cancer.

The study indicated that the average age of breast cancer onset in Urmia is lower than that in other regions of the country. Moreover, women with a history of hormone therapy and women with an increasing  number of pregnancies were at higher risk of developing breast cancer.

Ephedra intermedia is a dioecious plant of the Ephedraceae family whose male and female plants are quite similar in shape, but their biochemical differences are not known. The subject was the TLC and GC-MS study of fatty acids, phenols, essential oils, and alkaloids in male and female shoots of E. intermedia. Male and female shoots were collected from Markazi province in Iran, in spring. Alcoholic extract was obtained by mixing shoot powder with ethanol at 60 ° C. Phenols, fatty acids, and essential oil were separated from the alcoholic extract with ether and alkaloids with chloroform. Male and female ether extracts contained fatty acids, which appear male to be a good source of linolenic acid. The kind and amount of organic acids and phenolic of the two sexes were different. A large quantity of caprylic acid isoamyl ester was present only in females. 2, 6-Di-Tert-4-Methylphenol was much higher in both sexes than in the other compounds. A large number of essential oil compounds were found in the etheric extract of both sexes. The similarity of essential oil compounds between male and female plants was 32.4%. Total essential oils in female and male plants were 9.63 and 11.79 mgg-1DW. Males and females had a large number of alkaloids, but there wasn’t ephedrine and pseudoephedrine. Epherodxan and phendimetrazine in both sexes, ecgonine and aminopyrimidine in the male, and ergotamine and theacrin in the female, were six important medicinal alkaloids. Both sexes of E. intermedia are rich in bioactive compounds, but there was no ephedrine or pseudoephedrine.
