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.

Research reveals nuclear metabolic fingerprint in human cells

More than two hundred metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study published today in Nature Communications.

MSK uncovers how interacting mutations shield breast cancer

Researchers at Memorial Sloan Kettering Cancer Center (MSK) have made an important discovery about how genetic mutations in breast cancer patients can interact and drive resistance to certain drugs called CDK4/6 inhibitors. This finding, published in Nature, suggests a new strategy for predicting and preventing resistance to specific therapies based on the tumor's genetic profile.

AI trained on 9 trillion DNA letters predicts harmful mutations and designs new genomes

Scientists developed Evo 2, a large biological foundation model trained on about 9 trillion DNA base pairs that can analyse genomic sequences across bacteria, plants, and humans. The model predicts functional effects of genetic variants and can generate genome-scale DNA sequences, enabling new approaches to studying and designing biological systems.

Polytherapy improves blood pressure control and survival in metastatic breast cancer

Women with metastatic breast cancer often face multiple chronic conditions, and high blood pressure is among the most common. Nearly half of women in this study population had hypertension at diagnosis, with even higher rates among Black and Hispanic patients.

Assessing the value of modern US healthcare gains

Over two decades, medical care improvements increased health spans in the U.S. by 1.3 years and medical spending by $234,000 per person over their lifetime – or about $182,000 per additional healthy year of life gained – when measured from birth. These are among the key findings in a new in-depth national study published today in Value in Health.

Detecting the "scent" of ovarian cancer with AI

Using machine learning, an electronic nose can "smell" early signs of ovarian cancer in the blood. The method is precise and, according to the LiU researchers behind the study, it could eventually be used to find many different cancers. The study is published in the scientific journal Advanced intelligent systems.

Precision mRNA vaccine strategy shows early promise for improving TNBC relapse risk

An individualized neoantigen mRNA vaccine was tested in patients with early-stage triple-negative breast cancer and showed feasibility, safety, and strong T cell immune responses. Long-term follow-up suggested durable immune memory with encouraging relapse-free outcomes, though controlled trials are needed to confirm clinical benefit.
