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.

Pathology AI models show demographic bias in cancer diagnosis

Pathology has long been the cornerstone of cancer diagnosis and treatment. A pathologist carefully examines an ultrathin slice of human tissue under a microscope for clues that indicate the presence, type, and stage of cancer.

Frog-derived bacteria offer dual-action anticancer effects and high safety

A research team of Prof. Eijiro Miyako at the Japan Advanced Institute of Science and Technology (JAIST) has discovered that the bacterium Ewingella americana, isolated from the intestines of Japanese tree frogs (Dryophytes japonicus), possesses remarkably potent anticancer activity. This groundbreaking research has been published in the international journal Gut Microbes.

Breast cancer disrupts stress hormone rhythms in the brain

"The brain is an exquisite sensor of what's going on in your body," says Cold Spring Harbor Laboratory Assistant Professor Jeremy Borniger. "But it requires balance. Neurons need to be active or inactive at the right times. If that rhythm goes out of sync even a little bit, it can change the function of the entire brain."
