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.

German researchers aim to completely degrade breast cancer protein

Simply switching off a protein that helps breast cancer cells to grow? That is not enough for researchers at the University of Duisburg-Essen.

Mifepristone offers effective emergency contraception with fewer side effects

Emergency contraception containing mifepristone prevents more pregnancies with fewer side effects than some other common emergency contraceptive pills such as levonorgestrel, according to a new Cochrane review involving 87 trials.

Why might a higher BMI at 20 be linked to lower breast cancer risk later in life?

A large UK cohort study found that higher BMI at age 20 was associated with lower postmenopausal breast cancer risk, while higher BMI in later adulthood was linked to increased risk. Lower VAS percentage mammographic density appeared to explain part of the early-adulthood association, while fibroglandular volume showed a different relationship with life-course adiposity.

NUS scientists harness magnetic pulses to reprogram immune cells to fight breast cancer

Researchers from the National University of Singapore (NUS) have demonstrated an innovative approach for targeted breast cancer therapy using pulsed electromagnetic fields (PEMFs).

Breast density clue for cancer risk

Women with a higher Body Mass Index in early adulthood may have a lower risk of developing breast cancer after the menopause because of lasting changes in the structure of their breast tissue, according to researchers at The University of Manchester and Manchester University NHS Foundation Trust.

Scientists reveals how cancer-causing p53 mutations remain invisible to the immune system

One of the biggest challenges in cancer immunotherapy may not be that immune cells are too weak, but that some tumors give them too little to see.

Study identifies key factors in breast cancer survivors' sexual recovery

Sexual wellbeing can often be overlooked during a woman's recovery from breast cancer with many continuing to experience significant sexual and intimacy challenges long after treatment ends.

Salk scientists demonstrate B cells directly enhance killer T cell function

Cancer is the second leading cause of death in the United States, according to a 2026 Cancer Research Institute report. Cancer biologists are keenly aware of this statistic, as it drives them to innovations that revolutionize cancer care-innovations like immunotherapy.

Promising AI tool to speed up endometriosis diagnosis

Less than a second. That’s how long it takes for an emerging AI tool to detect signs of endometriosis through one simple scan. It’s a much faster process than the current seven-year wait for surgery and less invasive.

Researchers build prognostic model to guide end-of-life care in metastatic breast cancer

Oncologists know that intensive treatment rarely helps patients in their final days but recognizing when someone is entering that stage is difficult, especially in metastatic breast cancer, where an increasing number of effective treatments has helped prolong life and given patients and oncologists more treatment options.

Study provides a clearer picture of the extent of overdiagnosis in breast cancer screening

When women take part in breast cancer screening, they are informed that screening may detect cancers that would never have caused symptoms or problems during their lifetime. This is known as overdiagnosis.

Obesity suppresses natural protection against breast cancer growth

A research team at Huntsman Cancer Institute at the University of Utah (the U) has found that obesity prevents a biological process that kills cancerous cells, revealing a possible reason why obesity is a risk factor for breast cancer.

Breast cancer AI test finds no single chatbot excels across every measure

Researchers compared five large language models on breast cancer health information using 90 knowledge questions, 10 clinical cases, and 20 common patient concerns, with all prompts submitted in simplified Chinese. The models performed strongly on standardized knowledge overall, but differed in linguistic complexity and expert-rated completeness, readability, helpfulness, correctness, and safety.

New AI tool predicts breast cancer risk using repeated 3D mammograms

An artificial intelligence model that analyzes women's past and recent annual 3D mammograms is more effective at predicting five-year risk of developing breast cancer than a tool that uses only the most recent, single 3D mammogram, as well as an AI model that analyzes 2D mammograms, a new study shows.

Study links methylglyoxal stress to immunotherapy resistance in triple-negative cancer

The metabolism of cancer cells may play a key role in their ability to evade the immune system. This is demonstrated by a new study conducted by researchers at the University of Liège, which reveals how methylglyoxal stress – a by-product of tumor metabolism – promotes immunosuppression and the formation of metastases, and may contribute to resistance to immunotherapy and the progression of triple-negative cancer.
