“…This significant difference can be due to early detection using mammography scans and the better health care treatments available in the developed countries (Houssami et al, 2012). Early detection is closely associated with determining and closely monitoring the risk groups.…”

Background: When dealing with breast cancer, early detection is closely associated with determining and closely monitoring high risk groups. The aim of this study was to determine the preventable risk factors that are specific for our country, and to understand which risk factors were most predominant. Materials and Methods: The study was planned as a case-control design. Women diagnosed with breast cancer who visited the Surgery, Obstetrics and Gynaecology, and Radiation Oncology outpatient clinics of the Izmir Dokuz Eylul University (DEU) School of Medicine were accepted as the case group. Then a control group matched for age was established among females who visited the outpatient clinics on the same days. A questionnaire prepared by the researchers was implemented using a face-to-face interview technique. The Mann-Whitney U test was used in the comparisons of the group averages, and the Pearson chi-square test in the comparisons between groups. In order to determine the dominant risk factors, binary logistical regression test was implemented. Results: A total of 138 patients, 69 cases and 69 controls, were included in the study. A significant difference can be detected between the groups in terms of BMI, smoking, breast cancer prevalence among first degree family members, presence of breast cancer among distant family members, existence of other types of cancers among family members and the age of onset of menopause (p<0.05). Logistical regression analysis revealed that the presence of breast cancer among first degree relatives increased the risk of developing breast cancer 5.7 times. Conclusions: Although some results of this study are compatible with findings in the literature, some are not. In order to determine unique risk factors, there is a clear need for large-scale studies.

“…International comparisons of interval cancers are important but should be made with caution because of the lack of standardized surveillance methods. 13 We could only locate two meta-analyses of interval cancers. 16,19 A reason for that could be the lack of standardized methods and proper data.…”

Objectives To estimate the interval cancer incidence, its determinants and the episode sensitivity in the Norrbotten Mammography Screening Programme (NMSP). Setting Since 1989, women aged 40 -74 years (n ¼ 55,000) have been invited to biennial screening by the NMSP, Norrbotten county, Sweden. Methods Data on 1047 invasive breast cancers from six screening rounds of the NMSP (1989 -2002) were collected. We estimated the invasive interval cancer rates, rate ratios and the episode sensitivity using the detection and incidence methods. A linear Poisson-model was used to analyse association between interval cancer incidence and sensitivity. Results 768 screen-detected and 279 interval cancer cases were identified. The rate ratio of interval cancer decreased with age. The 50 -59 year age group showed the highest rate ratio (RR ¼ 0.52, 95% CI 0.41 -0.65) and the 70-74 year age group the lowest (RR ¼ 0.23, 95% CI 0.15 -0.36). The rate ratios for the early (0 -12 months) and late (13-24 months) interval cancers were similar (RR ¼ 0.18, 95% CI 0.15 -0.22 and 0.20, 95% CI 0.17-0.24). There was a significantly lower interval cancer incidence in the prevalence round as compared with the incidence rounds. According to the detection method the episode sensitivity increased with age from 57% in the age group 40 -49 years to 84% in the age group 70 -74 years. The corresponding figures for the incidence method were 50% and 77%, respectively. Conclusion Our study showed an interval cancer incidence of 38% and the episode sensitivity of 62 -73%, depending on the method of calculation. Our results are of clinically acceptable level and concert with the reference values of the European guidelines.

“…High breast density, which may be defined as heterogeneously dense or extremely dense breasts [5], also reduces the sensitivity of mammography, leading to increased risk of having an interval BC in women who have mammography screening [6]. For example, Boyd et al [7] showed that, relative to women with the lowest tissue density (density < 10% of the mammogram), women with density in ≥75% of the mammogram had an increased risk of BC (odds ratio 4.7; 95% CI 3.0-7.4) and a markedly increased risk of developing an interval BC (odds ratio 17.8; 95% CI, 4.8-65.9).…”
