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.

Fatty acids found to be a primary driver of triple-negative tumor growth

A team from Huntsman Cancer Institute at the University of Utah (the U) has found that triple-negative breast cancer is fueled by lipids and that these fatty acids are a key feature of obesity that promote tumor growth.

Study provides a roadmap for how health systems can improve lung cancer screening rates

Lung cancer screening might be the best-kept secret in health care today. Only about 16 percent of those who are eligible in the U.S. get screened for lung cancer, but a study coming out in NEJM Catalyst on Wednesday provides a roadmap for how health systems can improve those numbers.

Living near Superfund sites increases risk of aggressive breast cancer

Women living close to federally designated Superfund sites are more likely to develop aggressive breast cancers - including the hard-to-treat triple-negative subtype - according to new studies from Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.

Breakthrough in cancer therapy targets key protein interaction to suppress tumors

Researchers at the Francis Crick Institute and Vividion Therapeutics have identified chemical compounds that can precisely block the interaction between the major cancer-driving gene RAS, and a key pathway for tumor growth.

Perlmutter Cancer Center experts shine light on the rise of breast cancer in younger adults

Currently, breast cancer is the leading cause of cancer death in women age 20 to 49 in the United States. Compounding this concerning issue, younger patients are being diagnosed at more advanced stages, according to doctors at NYU Langone's Perlmutter Cancer Center, and this points to a greater need for screening, prevention, and breast cancer education.

Housing support programs tied to improved cancer detection among seniors

A new study led by researchers from the Johns Hopkins Bloomberg School of Public Health found that older adults receiving federal housing assistance were on average diagnosed at earlier stages with three common cancers-colon, breast, and non-small cell lung-compared to peer cancer patients who were not receiving assistance.

Whole genome sequencing may guide care for thousands of breast cancer patients

Whole genome sequencing offered to breast cancer patients is likely to identify unique genetic features that could either guide immediate treatment or help match patients to clinical trials for over 15,000 women a year, say scientists at the University of Cambridge.

Study reveals new strategy to block TNBC metastasis and restore chromosomal stability

Triple negative breast cancer (TNBC) is one of the most aggressive and hardest forms of breast cancer to treat, but a new study led by Weill Cornell Medicine suggests a surprising way to stop it from spreading. Researchers have discovered that an enzyme called EZH2 drives TNBC cells to divide abnormally, which enables them to relocate to distant organs.

Mastectomy may contribute to worse sexual health, psychosocial outcomes

While mastectomy is often a necessary and life-saving treatment option for many women with breast cancer, the surgery may contribute to worse sexual health, body image, and several other physical and emotional challenges after surgery, according to a new systematic review on the effects of mastectomy in women with breast cancer.

New algae gel provides realistic platform for breast cancer research

In 2020, right when Jane Baude was starting her Ph.D. research at UC Santa Barbara, she learned that a critical component of her experiment - the gel needed to grow and test mammary epithelial cells - wouldn't be available for nearly a year because of pandemic-related production issues. So, she and her adviser, professor Ryan Stowers, decided to pivot: Baude would engineer her own gel to study cells.

New software MaGNet automates analysis of breast tissue branching architecture

Branching isn't just for trees. This biological process occurs in animal development, enabling organs to perform complex functions. Branch-like structures form in lungs, kidneys, and breasts, among other places. Importantly, only in female mammary glands does most branching occur years after birth.
