[Relationship between fish consumption and decreased breast cancer risk]

Numerous animals models have shown the inhibitory effects of fish oil on tumor growth, due to its long - chain omega - 3 fatty acids. The association between fish intake and breast cancer was investigated in this case - control study. This retrospective study involved 197 women with breast cancer and 197 healthy subjects as control. Data were collected by questionnaires concerning demographic data, reproductive as well as breast cancer - related risk factors and a food frequency questionnaire. Information about fish intake one year prior to the disease onset was collected through the questionnaire. Qualitative variables and age were tested through chi square and Mann- Whitney statistical tests, respectively. Logistic regression analysis was used for final data analysis. The mean and standard deviation of age in case and control groups were 46.03 +/- 9.03 and 43.47 +/- 7.9 years, respectively. According to the final data analysis, shrimp [p=0.01] and tuna fish [p=0.002] intake were significantly influential in decreasing breast cancer risk. There was no significant association between breast cancer risk and total fish intake, its preparation and source [cultivated vs. marine]. There was no association between total fish intake, its source and/or preparation method and breast cancer. However, different fish species, shrimp intake, and use of conserved fish were important in reducing breast cancer risk

[ Rare Variation of Right Subclavian Artery Origin from Posterior Surface of Aortic Arch]

Several variations of aortic arch have been reported yet. In present study another variation of aoictic arch was reported. Right subclavian artery arises from posterior surface of the distal end of the aortic arch we present a variation of an aorticarch in which right subclavian artery arises from posterior surface of the distal end of the aortic arch and passing behind esophagus to reach right side of neck. Conclusion: Review of literature showed that regarding origin of the artery this variation was reported for tile first time by the authors It seems that the artery narrowed the position the esophagus However there were not any other sign of side effect on anatomical structure and of their blood supply

Cancer incidence and mortality in Ardabil: report of an ongoing population-based cancer registry in Iran, 2004-2006

Ardabil cancer registry is the first population-based cancer registry in Iran that was established in 2000. The first report from this registry revealed that Ardabil has one of the highest rate of gastric cardia cancer and the lowest rate of cervical cancer in the world. We aim to update the cancer incidence in this area by the second follow up report from this registry. Method: Data on all newly diagnosed cancer cases between 2004 and 2006 were actively collected. CanReg4 software was used for data entry and the data of cancer-related death were obtained from the comprehensive death registry system. More than 4300 new cases were registered during 3 years. Diagnosis of cancer was based on histopathology in 69%, clinical investigation 8%, clinical only 5%, and Death Certificate Only [DCO] in 18% of cases. In terms of age-standardized rate [/100,000], the five leading cancers in men [excluding skin cancer] were stomach [51.8], esophagus [19.5], bladder [13.1], lung and bronchus [10.8], and colorectal [9.6]; in women, they were stomach [24.9], esophagus [19.7], breast [11.9], colon and rectum [7.4], and brain tumors [6.9]. According to death registration data, upper gastrointestinal cancers constituted more than 43% of cancer-related death in Ardabil. The ASR for gastric cancer is among the highest rate for this cancer in male and female in the world. Most of the cancers, especially in female, have a significant increase compared to previous report from Ardabil. This is most likely due to the change in the registration practice
