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.

Machine learning model predicts liver cancer risk with high accuracy

A machine learning model that analyzes patient demographics, electronic health record data, and routine blood test results predicted a patient's risk of hepatocellular carcinoma (HCC), the most common type of liver cancer, with high accuracy.

Circulating tumor DNA predicts breast cancer relapse after treatment

Fragments of tumor DNA circulating in the bloodstream of patients with breast cancer can predict whether they are likely to relapse, especially when samples are taken after the patients have received treatments prior to surgery.

Breast cancer patients may avoid lymphedema with radiotherapy approach

Patients with breast cancer may be able to avoid lymphedema, which can occur after surgery to remove lymph nodes in the armpit (the axilla), by having radiotherapy instead.

Breast cancer cells exploit the lung's repair system to support tumor growth

Researchers at the CU Anschutz Cancer Center have discovered how breast cancer cells that spread to the lungs may take advantage of the body's natural healing response and how a commonly used drug might slow that process.

Cancer-fighting antibodies may trigger autoimmune brain disorders

Consider two seemingly unrelated medical puzzles. First: Every day, our bodies produce hundreds of billions of new cells, many of which are mutated.

New approach helps immune cells find and attack solid tumors

A technique that transforms immune cells into cancer-seeking bloodhounds may overcome a roadblock that has hampered immunotherapy for solid tumors, according to a new study by Stanford Medicine researchers.

Personalized radiotherapy reduces the risk of breast cancer recurrence

The chances of breast cancer recurring remain very low when patients are treated with radiotherapy that is tailored to their individual risk following chemotherapy and surgery. These are the findings of a ten-year study presented at the 15th European Breast Cancer Conference (EBCC15) in Barcelona today (Wednesday).

Polyurethane-coated implants may reduce scarring after breast reconstruction surgery

Women who are treated with mastectomy for breast cancer often choose to have surgery to reconstruct the breast using an implant.

Blood-based test helps personalize breast cancer care for older patients

For women age 70 and over with a common form of breast cancer, determining "the right size" of treatment can be challenging, in part because clinicians have limited tools to guide individualized treatment decisions.

New mechanism drives adverse tumor remodeling during breast cancer progression

A research group led by Professor Cecilia Sahlgren at Åbo Akademi University (Finland) and the InFLAMES Research Flagship has identified a new mechanism directing the adverse remodeling of tumor tissue during breast cancer progression.

Cancer cells rely on glutathione as fuel for growth

Researchers discovered an antioxidant, glutathione, that cancer cells appear to be "addicted to" as fuel, opening new pathways for investigation and a potential drug that can restrict the way tumors use this nutrient.

Combination therapy shows promise for leptomeningeal metastasis in breast cancer

Patients with leptomeningeal metastasis (LM) have historically had few treatment options. Now, researchers from The University of Texas MD Anderson Cancer Center have found a combination of targeted therapies, tucatinib and trastuzumab, plus the chemotherapy drug, capecitabine, may improve symptoms and extend survival in some breast cancer patients with LM.
