Routine, population-based mammographic screening for breast cancer has been implemented nationally in Japan for the past decade. The objective of this study was to evaluate the knowledge of the general public and of nurses concerning breast screening practices in Japan, especially with regards to the benefits and risks of breast cancer screening. In 2014, a questionnaire regarding the benefits and risks of breast cancer screening was administered to women who underwent breast cancer screening and to registered nurses. The questionnaire was distributed to 1,649 women and 1,905 registered nurses. Completed questionnaires were returned by 1,552 (94.1%) of the screened participants and 1,710 (89.8%) nurses. The majority of the screened participants and registered nurses believed that screening prevented or reduced the risk of developing breast cancer (86% and 62%, respectively); that screening reduced the mortality risk of breast cancer by more than 50% (69% and 60%, respectively); and that 10 years of regular screening for 50-year-old women could prevent ≥ 10 breast cancer deaths per 1,000 women (62% and 61%, respectively). Women in the target population and registered nurses were aware that earlier diagnosis led to better prognosis, but demonstrated misconceptions regarding other aspects of the benefits and risks of breast cancer screening. In Japan, all women should be educated on both the benefits and risks of breast cancer screening to enable them to make an informed decision on whether to participate in the mammographic breast cancer screening program.

In this study, we synthesized 12 monofunctional tridentate ONS-donor salicylaldimine ligand ()-based Ru(II) complexes with general formula [(Ru()(-cymene)]·Cl (-), characterized by H NMR, C NMR, UV, FT-IR spectroscopy, HR-ESI mass spectrometry, and single-crystal X-ray analysis showing ligand's orientation around the Ru(II) center. All 12 of these 12 complexes were tested for their anticancer activities in multiple cancer cells. The superior antitumor efficacy of , , and was demonstrated by reduced mitochondrial membrane potential, impaired proliferative capacity, and disrupted redox homeostasis, along with enhanced apoptosis through caspase-3 activation and downregulation of Bcl-2 expression.

Background: To investigate the performance of contrast-enhanced ultrasound(CEUS) parameters of metastatic axillary lymph nodes (ALNs) before and after two courses of neoadjuvant chemotherapy (NAC) in breast cancer patients in predicting the efficacy of NAC.
Methods: A total of 41 postoperative breast cancer patients were selected. All patients underwent NAC, and ALN biopsy was positive before chemotherapy.

Unlabelled: Engineered three-dimensional (3D) tissue culture platforms are useful for reproducing and elucidating complex in vivo biological phenomena. Spheroids, 3D aggregates of living cells, are produced based on physicochemical or microfabrication technologies and are commonly used even in cancer pathology research. However, conventional methods have difficulties in constructing 3D structures depending on the cell types, and require specialized techniques/lab know-how to reproducibly control the spheroid size and shape.

Mucinous carcinoma of the breast, also known as colloid carcinoma, is an uncommon type of differentiated adenocarcinoma, representing only 2% of all invasive breast carcinomas. It usually occurs in women ≥ 60 years of age. Mucinous carcinoma is characterized by clusters of epithelial tumour cells suspended in pools of extracellular mucin and is further divided in 2 subgroups, pure and mixed.
