Breast Cancer

Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

HER-2 Positive Breast Cancer

Human epidermal growth factor receptor 2 (HER2) is a gene that can play an important role in the development of some types of breast cancer. This gene is also sometimes referred to as Erc-B2 receptor tyrosine kinase 2 (ERBB2). This gene is involved in the production of HER2 proteins, which are present on breast cells as receptors to control the growth, division, and repair of the cells.

Scientists map protective cell networks hiding dormant breast tumor cells

Researchers at the MRC Laboratory of Medical Sciences (LMS), Imperial College London and UCL Genetics Institute have created a detailed map of cells within breast tumors and identified distinct neighborhoods of proliferating and dormant cells.

Exposure to fungicides and insecticides alters onset of puberty in girls

The study, which tracked more than 500 Spanish girls between the ages of 7 and 10, links the presence of certain fungicides in urine to early menarche and that of the insecticide chlorpyrifos to delayed menarche, highlighting the impact of pesticides on pubertal development.

Dual immunotherapy with neoadjuvant chemotherapy shows encouraging activity in ERBB2-negative breast cancer

A combination of two immunotherapy drugs showed encouraging activity when added to standard chemotherapy given prior to surgery for patients with high-risk, early-stage HER2-negative breast cancer, according to phase 2 clinical trial results from the ongoing I-SPY2 clinical trial platform.

Low-fat diet lowers dietary glycation compounds for years in postmenopausal women

Researchers analyzing dietary data from 40,209 postmenopausal women found that a low-fat pattern emphasizing fruits, vegetables, and grains was associated with sustained reductions in estimated dietary advanced glycation end-product intake over approximately seven years. The findings suggest broad dietary changes may lower dAGE intake without specific cooking instructions, although the study did not measure biological AGE exposure or determine whether the reductions influenced breast cancer outcomes.

New cancer vaccine harnesses COVID-19 immune memory to fight tumors

In a discovery that could redefine the future of cancer immunotherapy, scientists from Celloram Inc., University Hospitals and Case Western Reserve University have developed a novel cancer vaccine platform that transforms the impact of the largest immunological event in modern history – a synchronized mass immune memory generated through SARS-CoV-2 infection and vaccination – into a powerful ally against cancer.

Engineered extracellular vesicles dramatically improve cancer detection sensitivity

Anyone afflicted with cancer will often face a long and difficult journey. The early stages of any medical intervention will necessarily include a biopsy, tissue sample collection, such as a liquid biopsy which uses a blood sample.

Thymulin curbs age-related inflammation and slows breast tumors in mice

Thymulin reduced age-associated inflammatory myeloid cells and slowed breast-tumor growth in aged mice by suppressing NF-κB signaling. The peptide also restored anti-PD-L1 responsiveness in aged mouse models, while human cell and tumor data supported an age-linked inflammatory myeloid profile.

DNA enhancer hubs control cancer genes in prostate tumors

Enhancers are pieces of DNA that act like switches, regulating when genes are turned on and off and how strongly they are activated.

Common heart risk calculators effectively predict certain types of cancer

Risk calculators that doctors use to estimate a person's risk of a heart attack or stroke work about as well for predicting certain cancers, according to a new study by UCL (University College London) researchers.

New target makes cancer cells vulnerable to immune destruction

Researchers at the University of Illinois Chicago have identified a molecular switch that helps determine whether cancer cells remain soft and difficult to destroy or become stiff enough for the immune system to attack.

LIG1 loss reveals new treatment strategy for aggressive breast cancer

Loss of one copy of the DNA Ligase I (LIG1) gene in triple-negative breast cancers (TNBC) with TP53 mutations confers resistance to chemotherapy, but researchers at Baylor College of Medicine and collaborating institutions have identified a vulnerability in these cells and used it to their advantage.

New model improves short- and long-term disease risk prediction

Researchers developed ALADYNOULLI, a Bayesian generative model that combines longitudinal health records, age, and polygenic risk to identify reproducible disease signatures across more than 683,000 participants. In UK Biobank testing, the framework achieved stronger short- and long-term risk discrimination than established clinical scores while revealing disease subgroups and genetic associations.

Targeted nanoparticles destroy tumor cells by triggering cuproptosis

A promising cancer treatment strategy called cuproptosis, which uses copper-dependent cell death to eliminate tumor cells, faces a major challenge: many approaches require adding external copper, potentially increasing toxicity beyond the tumor.

Breast and prostate cancer survival worsens with metabolic syndrome

A SEER-Medicare analysis of more than 200,000 adults aged 66 and older found that metabolic syndrome was associated with about twice the adjusted hazard of death from any cause after breast or prostate cancer. The condition was also linked to higher cancer-specific, cardiovascular-specific, and liver-failure-specific mortality, although the observational design prevents causal conclusions.
