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.

Survey highlights widespread emotional impact of cancer on patients and their families

A cancer diagnosis is a life-changing event for patients that can cause short- and long-term mental health concerns as they shift to living within a new timeline driven by weeks or months between medical follow-up appointments.

Acromegaly linked to higher cancer risk

People with the rare growth hormone disorder acromegaly have a significantly higher risk of developing various types of cancer, often at ages younger than typically seen in the general population, according to a study being presented Monday at ENDO 2025, the Endocrine Society's annual meeting in San Francisco, Calif.

Long sitting hours raise breast cancer odds for inactive obese women

Prolonged daily sitting is linked to a higher prevalence of breast cancer in obese women, but only among those who are physically inactive. Regular physical activity eliminates this association, highlighting the importance of movement for breast cancer prevention in high-risk groups.

Tirzepatide reduces obesity-associated breast cancer growth in mouse model

The anti-obesity medication tirzepatide, marketed as Mounjaro for diabetes and Zepbound for obesity, reduced obesity-associated breast cancer growth in a mouse model, according to a study being presented Saturday at ENDO 2025, the Endocrine Society's annual meeting in San Francisco, Calif.

Uncovering the hidden architecture of the genome in three dimensions

In biology textbooks and beyond, the human genome and DNA therein typically are taught in only one dimension. While it can be helpful for learners to begin with the linear presentation of how stretches of DNA form genes, this oversimplification undersells the significance of the genome's 3D structure.

Watch: She’s at high risk of breast cancer. She moved, and her screening costs soared.

Kelli Reardon undergoes an MRI twice a year to screen for breast cancer, a measure she said she must take to protect her health. Her mother died of the disease at age 48, putting Reardon at higher risk, and Reardon has dense breast tissue, which makes it harder to detect a growth through a mammogram.
