Breast cancer is one of the most common cancers among women worldwide. Therefore, further research in this area remains necessary. In pursuit of cancer treatment, the use of aquatic and marine resources has been considered in recent years. Marine algae create a wide variety of metabolites with different biological activities, and their anticancer properties have been reported in several studies. With particles ranging in size between 30 and 100 nm in size, exosomes are a class of cell-released extracellular vesicles that contain DNA, RNA, and proteins. Nontoxic properties and lack of an immune response are critical considerations in the medical use of exosome nanoparticles. Studies have demonstrated that exosomes are used for cancer therapy and in several drug delivery trials; however, no study so far has been done on exosomes derived from marine algae. Research has shown that three-dimensional (3D) models of cancer are advantageous for studying drug effects. This hypothesis aims to design a 3D model of breast cancer in vitro and evaluate cell growth after treatment with a marine algae-derived exosome.

Air pollution and breast cancer risk: a Mendelian randomization study.

Previous research yields inconsistent findings on the association between air pollution and breast cancer risk, with no definitive causal relationship established. To address this, we conducted a two-sample Mendelian randomization study on data from the IEU open GWAS databases and the Breast Cancer Association Consortium to explore the potential link between air pollution (including PM, PM absorbance, PM, PM, NO, and NO) and breast cancer risk. We found that PM (odds ratio (OR) = 1.

Background: The low incidence and poor prognosis primary trastuzumab resistance (PTR) in HER2-positive breast cancer has limited research into possible treatments. Thus, it remains unclear whether this group of patients could benefit from nontargeting HER2 antiangiogenic therapy.
Patients And Methods: We collected the medical data for HER2-positive patients with PTR who received apatinib 250 mg and trastuzumab-based chemotherapy (ATBC) between March 18, 2017, and March 31, 2022.
Prognostic value of tumor-infiltrating lymphocyte subtypes and microorganisms in triple-negative breast cancer.

Tumor-infiltrating lymphocytes (TILs) are key components of the tumor microenvironment (TME) and serve as prognostic markers for breast cancer. Patients with high TIL infiltration generally experience better clinical outcomes and extended survival compared to those with low TIL infiltration. However, as the TME is highly complex and TIL subtypes perform distinct biological functions, TILs may only provide an approximate indication of tumor immune status, potentially leading to biased prognostic results.

Background: Breast cancer survivors face unique challenges in breastfeeding decisions. Limited research exists on the experiences and decision-making processes of young women with breast cancer regarding breastfeeding.
Objective: To explain the decision-making processes of young women with breast cancer in relation to breastfeeding throughout the cancer trajectory.

Purpose: Mammary carcinoma is comprised heterogeneous groups of cells with different metastatic potential. 4T1 mammary carcinoma cells metastasized to heart (4THM), liver (4TLM) and brain (4TBM) and demonstrate cancer-stem cell phenotype. Using these cancer cells we found thatTGF-β is the top upstream regulator of metastatic process.
