Breast Cancer in Working-Age Men: A Population-Based Investigation of Global, Regional, and National Disease Burdens Between 1990 and 2021.

Background: The breast cancer (BC) disease burden in working-age men was investigated between 1990 and 2021.

Methods: Age-standardized incidence rates (ASIRs), prevalence rates ASPRs), and death rates (ASDRs), as well as age-standardized disability-adjusted life years rate (DALYs) on global, regional, and national levels between 1990 and 2021, were determined to assess the BC disease burden in working-age men (aged 15-64 years), together with risk factor and health inequality analyses.

Results: Globally, the ASIR, ASPR, ASDR, and age-standardized DALY rate in 2021 were 0.

Tumor-colonizing metabolically reprograms the tumor microenvironment and promotes breast ductal carcinoma.

Unlabelled: The correlation between the microbiota found in tumors and tumor development is being progressively understood, specifically regarding its involvement in the initiation and advancement of tumors. We examined a total of 102 samples, examining the microbial composition at the species level in each person unveiled significant variations in both the microbial makeup and tumor proportions among individuals, examining the fluctuating alterations in the microbial profile during breast cancer advancement and progression. The levels of expression for were notably elevated in the tumor groups when compared to the para-cancer normal group, aligning with the results obtained from qRT-PCR analysis.

Research progress in tumor angiogenesis and drug resistance in breast cancer.

Angiogenesis is considered a hallmark pathophysiological process in tumor development. Aberrant vasculature resulting from tumor angiogenesis plays a critical role in the development of resistance to breast cancer treatments, exacerbation of tumor hypoxia, decreased effective drug concentrations within tumors, and immune-related mechanisms. Antiangiogenic therapy can counteract these breast cancer resistance factors by promoting tumor vascular normalization.
