Background: The relationship between meat intake and breast cancer has been inconsistent .
Objective: The aim of this work was to evaluate the association between meat intake and breast cancer, in women.
Design: A case-control study with 250 consecutive, newly diagnosed breast-cancer-female-patients (56 ± 12 years) and 250, one-to-one age-matched controls was conducted. A standardized, validated questionnaire assessing various socio-demographic, clinical, lifestyle and dietary characteristics was applied through face-to-face interviews. Data on consumption of red, white, processed and grilled meat were also recorded. Overall dietary habits were assessed through the level of adherence to the Mediterranean diet using the MedDietScore (theoretical range 0-55).
Results: Processed meat intake, even for 1-2 times/week,was associated with a 2.7-fold (OR= 2.65, 95% CI 1.36, 5.14) (p= 0.004) higher likelihood of having breast cancer, while daily intake increased the likelihood by a 2.8-fold (OR = 2.81, 95% CI 1.13, 6.96) (p = 0.026), after various adjustments made. Red, white and grilled meat intake was not significantly associated with the outcome when the same adjustments were made.
Conclusions: This study suggested that only daily processed-meat intake was consistently associated with increased odds of breast-cancer.

Background: Over the past twenty years, the post-cancer rehabilitation has been developed, usually in a hospital setting. Although this allows better care organization and improved security, it is perceived as stressful and restrictive by the "cancer survivor". Therefore, the transfer of benefits to everyday life is more difficult, or even uncertain.

Purpose: Many breast centers are unable to provide immediate results at the time of screening mammography which results in delayed patient care. Implementing artificial intelligence (AI) could identify patients who may have breast cancer and accelerate the time to diagnostic imaging and biopsy diagnosis.
Methods: In this prospective randomized, unblinded, controlled implementation study we enrolled 1000 screening participants between March 2021 and May 2022.

Background: The identification of circulating potential biomarkers may help earlier diagnosis of breast cancer, which is critical for effective treatment and better disease outcomes. We aimed to study the role of circ-FAF1 as a diagnostic biomarker in female breast cancer using peripheral blood samples of these patients, and to investigate the relation between circ-FAF1 and different clinicopathological features of the included patients.
Methods And Results: This case-control study enrolled 60 female breast cancer patients and 60 age-matched healthy control subjects.

Introduction: Little is known about the symptom burden of breast cancer survivors with early-stage disease. Many studies have focused on symptoms of patients who are undergoing or recently completed systemic therapy. However, with the increased use of Oncotype DX, the proportion of early-stage hormone receptor-positive patients who undergo chemotherapy has declined, making existing studies of the symptom experience less useful for these patients.
