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.

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.
