Breast cancer is a major health issue in all countries affecting thousands of women. Its causes are unknown and the national and international strategies to reduce its morbidity and mortality levels are based on early detection of cancer through screening and treatment according to clinical guidelines. Thus, knowledge of which women are at risk and why they are at risk is therefore essential component of disease prevention and screening. In 2015, an estimated 231,840 new cases of invasive breast cancer are expected to be diagnosed in women in the United States, along with 60,290 new cases of non-invasive (in situ) breast cancer. The purpose of this study is to provide a more detailed analysis of the breast cancer distribution in the United States by comparing the spatial distribution of breast cancer cases against physical environmental factors using Geographic Information System (GIS). Further, it gives background information to the GIS and its applications in health-related research.

Feminist geography and geographic information system(GIS) have been the most dynamic research areas over the last decade. Unfortunately, high breast cancer mortality rates have been reported in the northern part of the United states, with recent attention focused on the northern part of the United States. In this article, the authors investigate whether such a high rate of breast cancer is evenly spread in northern parts. The purpose of this article is to provide a more detailed analysis of the breast cancer distribution in the United States by comparing the spatial distribution of breast cancer cases against physical environmental factors using Geographic Information System (GIS). Further, it gives background information to the GIS and its applications in health-related research.

From 1937 to 1960, 1051 women with cystic disease of the breast were hospitalized at the National Cancer Institute of Milan; 1008 of them were followed for a period ranging from 1 to 26 years, with an average of 8.5 years. All cases were histologically proved. Twenty-one of the patients developed a cancer of the breast; 16 in the breast with the cystic disease, 5 in the contralateral breast. In 667 cases the disease was histologically classified as «simple cystic disease »; 12 of these cases had a breast cancer. In 384 cases the disease was classififed as «hyperplastic cystic disease»; 9 of these developed a cancer of the breast. The follow-up of the 1008 cases provided 8539 person-years at risk; the number of the expected breast cases was calculated on the basis of the Dorn and Cutler data on morbidity of cancer in 10 metropolitan areas of the United States. The number of expected breast cancer was 12.2; the number of observed cases was 21, the ratio between observed and expected cases being 1.71.

Studies have suggested that outcomes from breast cancer are improved when treatment is rendered at high-volume teaching centers. The current study was undertaken to examine the impact of facility type on the presentation and treatment of “early” breast carcinoma across the United States. Breast cancer data were available from the American College of Surgeons National Cancer Database. The cohort consisted of 305,358 patients presenting with in situ cancers and no prior treatment from 2000 to 2008. Data were stratified by type of treatment facility, “invasive” versus “noninvasive” nature of the tumor, and treatment performed. Only 15 per cent of patients presented to community cancer centers (CCCs). Despite this, a greater percentage presented with invasive disease at CCCs (82.1%) compared with comprehensive community cancer centers (CCCCs; 80%) or teaching/research facilities (T/Rs; 70.2%). In examining the in situ cohort, a higher percentage of patients at CCCs were treated with breast conservation than at CCCCs or T/Rs. Although small, these differences were statistically significant. These data do not support the contention that only “early” cases of breast cancer present and are treated at community centers. In early breast cancer, patients are as likely to receive state-of-the-art treatment at a CCC as they are at a T/R.

Breast cancer is one of the leading types of preventable cancer among women in the United States. Despite improvements in mammography and early detection techniques for breast cancer, special population groups within the United States continue to experience high incidence and mortality rates. This paper focuses on Kentucky's underserved populations. The research objectives were to: 1) identify the factors that motivate women at risk to be screened for breast cancer; and, 2) identify the factors that deter women at risk from being screened for breast cancer. A combination of quantitative (survey n=407) and qualitative (focus groups=19; in-depth interviews=58) research methods were used to examine factors that influence mammography use. Factors that motivate women to have mammograms include: physician referral; the belief that early detection will improve breast cancer outcomes; and, the belief that a mammogram is an effective test. Factors deterring women from having mammograms include: lack of physician referral; cost; and, the belief that mammography is dangerous. Research findings point to the need for a comprehensive, integrated approach to increasing utilization rates. This approach includes recommendations for increasing physician referrals, modifying service delivery, training staff, and development of client education materials and a public information campaign. These recommendations have been incorporated into a social marketing plan to increase utilization of mammography services in the state of Kentucky.
