“…Our findings suggest that mammographic screening has played a major role in the increase in incidence of breast cancer in Croatia (13), but the increase had started well before the screening became widely available (44). The increasing trends observed before 1995 can be attributed to greater disease awareness, greater detection by physical breast examination (either self-examination or examination by physician or a nurse), changes in reproductive factors, increasing use of hormone treatment after menopause, and increasing rates of obesity (39).…”

AimTo investigate urban-rural differences in the distribution of risk factors for breast cancer.MethodsWe analyzed the data from the first round of the “Mamma” population based-screening program conducted in Croatia between 2007 and 2009 and self-reported questionnaire results for 924 patients with histologically verified breast cancer. Reproductive and anthropometric characteristics, family history of breast cancer, history of breast disease, and prior breast screening history were compared between participants from the city of Zagreb (n = 270) and participants from 13 counties with more than 50% of rural inhabitants (n = 654).ResultsThe screen-detected breast cancer rate was 4.5 per 1000 mammographies in rural counties and 4.6 in the city of Zagreb, while the participation rate was 61% in rural counties and 59% in Zagreb. Women from Zagreb had significantly more characteristics associated with an increased risk of breast cancer (P < 0.001 in all cases): no pregnancies (15% vs 7%), late age of first pregnancy (≥30 years) (10% vs 4%), and the most recent mammogram conducted 2-3 years ago (32% vs 14%). Women from rural counties were more often obese (41% vs 28%) and had early age of first live birth (<20 years) (20% vs 7%, P < 0.001 for both).ConclusionIdentification of rural-urban differences in mammography use and their causes at the population level can be useful in designing and implementing interventions targeted at the reduction of inequalities and modifiable risk factors.

“…This is very unlikely since generalisation of mammographic screening has been itself at the origin of sharp increases in the incidence of small breast cancers, many of which are deemed to be of low malignant potential [71]. In The Netherlands, no increase in proportions of advanced cancers in women not attending screening was observed [53], and there were no time changes in the incidence of advanced breast cancer in women <50 and >69 years of age in which screening is rare [8].…”

Background: Breast cancer mortality is declining in many Western countries. If mammography screening contributed to decreases in mortality, then decreases in advanced breast cancer incidence should also be noticeable.Patients and methods: We assessed incidence trends of advanced breast cancer in areas where mammography screening is practiced for at least 7 years with 60% minimum participation and where population-based registration of advanced breast cancer existed. Through a systematic Medline search, we identified relevant published data for Australia, Italy, Norway, Switzerland, The Netherlands, UK and the USA. Data from cancer registries in Northern Ireland, Scotland, the USA (Surveillance, Epidemiology and End Results (SEER), and Connecticut), and Tasmania (Australia) were available for the study. Criterion for advanced cancer was the tumour size, and if not available, spread to regional/distant sites.Results: Age-adjusted annual percent changes (APCs) were stable or increasing in ten areas (APCs of −0.5% to 1.7%). In four areas (Firenze, the Netherlands, SEER and Connecticut) there were transient downward trends followed by increases back to pre-screening rates.Conclusions: In areas with widespread sustained mammographic screening, trends in advanced breast cancer incidence do not support a substantial role for screening in the decrease in mortality.

“…This is likely to be due to screening pilots in some areas of the state prior to the introduction of the universal screening program, as well as the availability of diagnostic mammography in private clinics and some public hospitals in New South Wales. The frequency of these mammograms has been shown to have increased substantially before the state screening program was universally available (but when its existence was widely publicised 24 ). This has previously been interpreted as diagnostic mammography among women without clinical symptoms 25 .…”

Objective: To compare breast cancer incidence in England and Australia by age, extent of disease and deprivation. Methods: We analysed data for women aged 15–99 years diagnosed with breast cancer in England or Australia during the period 1990 to 1994, and in West Midlands or New South Wales during the period 1980 to 2002. We calculated three‐year rolling average incidence rates and incidence rate ratios (IRR) between West Midlands and New South Wales by age, extent of disease and category of deprivation. Results: Breast cancer incidence was higher in England than in Australia, and in West Midlands than in New South Wales but became more similar over time. Socio‐economic differences in incidence were greater in New South Wales than in West Midlands. The most deprived women in West Midlands were diagnosed at a later stage of disease than the most deprived women in New South Wales. Incidence among elderly women was higher in West Midlands than in New South Wales. There were also high proportions of tumours with unknown stage among elderly women in West Midlands. Conclusions: Although the overall incidence of breast cancer is similar, differences by age, extent of disease and deprivation exist. Implications: The underlying reasons for these patterns require further examination.
