Abstract This paper presents a Microwave Imaging apparatus for breast cancer detection, aiming at early diagnosis, an effective way of reducing mortality rates. In 2020, breast cancer has surpassed lung cancer cases worldwide, with more impact in low-income countries, which motivates seeking a non-invasive and affordable screening equipment. Focusing on low-cost and portability, a US$150.00 embedded hardware transceiver plus antennas platform has been picked out, together with the development of a dry-coupling silicone rubber bra hold by a handheld device. Initially, a losses study to analyze the hardware ability to detect malignant tumors depth in the breast was conducted. Next, simulations and tests employing the platform along with a breast phantom were carried out. This phantom mimics the dielectric breast tissue properties while a confocal algorithm was applied to backscattered signals to generate reconstructed images. Results established a correspondence between simulated and experimental data, SCR and SMR above 7.0 dB and 23.0 dB, respectively, in the resulting images and tumor location precision below 0.3 cm. Based on that, the low-cost portable proposed system results showed its ability as an adjunct early breast cancer diagnosis tool.

Purpose The increasing incidence of breast cancer during pregnancy and postpartum in Nigeria remains a source of concern and management dilemma. Integrating a screening program into existing antenatal and postnatal services might provide a real opportunity to promptly detect and plan treatment in low-income countries. The objective of this work was to describe the profile of women referred for additional investigation after clinical breast examination (CBE) in pregnancy and during lactation and to identify factors that might influence uptake. Methods We used an explanatory sequential mixed-methods approach. A cross-sectional survey described 206 women who were referred for free breast ultrasound scan (BUS) after CBE at recruitment, in the third trimester, and at 6 weeks and 6 months postpartum in three different public health centers in Ibadan, Nigeria. We conducted 16 in-depth interviews (IDIs) to explore reasons for their decisions on BUS. Quantitative data were summarized and multiple logistic regression was performed to determine the association between explanatory variables and BUS uptake at P < .05. IDIs were transcribed and analyzed using a thematic approach. Results Mean age of participants was 28.5 ± 5.14 years. The majority of participants (61.7%) presented for BUS. Study participants were mostly recruited from secondary health facilities (71.8%), had less than a higher national diploma education (76.7%), and were of the Yoruba ethnic group (94.7%). History of breast self-examination practice was reported by 52 participants (25.24%) and 20 (9.71%) had ever performed CBE. Women with a higher national diploma level of education or greater were more likely to have undergone BUS (adjusted odds ratio, 4.41; 95% CI, 1.13 to 17.31). Reasons mentioned during IDI for avoiding BUS were financial constraint for breast cancer treatment and management after diagnosis, fear of an unfavorable BUS report, psychological wellbeing after breast cancer diagnosis, lack of trust in the health system, lack of information on BUS, and an assumption of none or less aggressive symptoms. Most of the women interviewed (93.8%) informed their husbands about the BUS referrals and they all received support. Conclusion The majority of participants who were educated presented for BUS. Some women declined additional evaluation of their breasts for fear of financial constraints, breast cancer diagnosis, and unknown fear of psychological implications.

e20620 Background: Financial security is often viewed as a social determinant of health, especially in low income populations. Among low-income breast cancer patients, identifying early predictors of financial security could aid researchers in developing tools to improve long-term financial stability. Methods: A consecutive sample of 921 low-income, underinsured/uninsured women treated for stage 0-III breast cancer was surveyed 6 months following diagnosis. Women were surveyed again at 18, 36 and 60 months. Eligible participants were English/Spanish speaking women enrolled in California’s Breast and Cervical Cancer Treatment Program. The relationship between clinical, demographic, economic, health variables and adequacy of financial resources at 60 months was explored using logistic regression. Results: Of 590 women with complete data at 60 months, 45% said they did not have adequate financial resources 60 months following the diagnosis of breast cancer. Of these women, 74% (n=197) did not have adequate financial resources at 6 months, and 26% (n=70) went from having adequate financial resources at 6 months to not at 60 months. In univariate analyses, predictors of 60 month financial inadequacy included: employment status at 6 months (p=.017), ethnicity (p<.001), number of people living in the home (p=.004), age (p=.024), and adequate financial resources at 6 months (p<.001). In multivariate analyses, ethnicity (p=.008) and adequate financial resources at 6 months (p<.001) were independent predictors. Compared to non-Latina whites, Latinas had the lowest odds of having adequate financial resources at 60 months (adjusted OR: 0.51 95% CI: 0.32-0.82), followed by all other ethnicities (adjusted OR: 0.80 95% CI: 0.44-1.44). Conclusions: Financial stability after breast cancer diagnosis continues to be an issue faced by low income women five years following initial diagnosis. Ethnicity was an independent predictor of long-term financial stability. Latinas were especially likely to have inadequate financial resources 5 years after diagnosis. Long-term financial stability was not associated with any of the treatment and health or disease-related measures.

Incident Breast Cancer

120 Background: High-deductible health plans (HDHP) are associated with breast cancer treatment delays of up to 10 months, but their impact on health outcomes is unknown. We hypothesized that, compared with women in generous plans, HDHP members would present with more advanced disease and thus experience higher total costs of early care. Methods: We studied 2004-2014 claims data from a large US health insurer. We included women aged 25-64 who were in traditional low-deductible (≤$500) health plans for 1 baseline year then experienced either an employer-mandated switch to HDHPs (≥$1000) for up to 4 or years or an employer-mandated continuation in low deductible plans. We defined the HDHP switch date as the index date. We then restricted to women who developed incident breast cancer after the index date. Using baseline characteristics, we closely matched HDHP members with incident breast cancer to contemporaneous women with incident breast cancer who remained in low-deductible plans. We measured total costs of all health care services in the 60 days after incident breast cancer diagnosis as a proxy for the intensity of incident breast cancer care. We used negative binomial regression adjusted for baseline characteristics to compare total 60-day costs among HDHP and control members. We also subset analyses to low-income women. Results: We included 1514 HDHP members and 9283 matched controls. 60-day costs after incident breast cancer diagnosis were $24,151 (95% CI: $22,766, $25,535) among HDHP members and $22,474 ($21,952, $22,996) among controls, an absolute difference of $1677 ($197, $3156) and a relative difference of 7.5% (8.1%, 14.1%). Low-income HDHP members had corresponding absolute and relative differences of $2653 ($368, $4939) and 12.5% (1.5%, 23.5). Conclusions: HDHP members with incident breast cancer had 7.5% higher health care costs in the 60 days after incident breast cancer than women with more generous coverage, a finding driven 12.5% higher costs among low-income HDHP members. Results raise concerns that delays in breast cancer care among HDHP members are associated with more advanced disease and adverse outcomes.
