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.

Prostate cancer overdiagnosis risk increases substantially in older men

Researchers at Queen Mary University of London have found that the likelihood of prostate cancer overdiagnosis – the detection of a cancer that would never have been diagnosed during a patient's lifetime but for PSA screening – is low in younger men but rises substantially with old age.

Why do the deadliest cancers still get less NIH research funding?

Researchers found that NIH funding for major US cancers does not consistently align with lethality, with highly fatal cancers such as pancreatic cancer and small-cell lung cancer receiving far less funding per estimated death than breast or prostate cancer. The study argues that incidence alone is not enough and that funding decisions should better incorporate mortality, survival, and mortality-to-incidence ratios.

Chronic wildfire smoke exposure may raise long-term cancer risks

Exposure to wildfire smoke was associated with a significantly increased risk of lung, colorectal, breast, bladder, and blood cancer, according to results from a study presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, held April 17-22.

Long-term exposure to air pollution (PM2.5) raises risk of developing cancer by 11 % and of dying from cancer by 12 %

The Union for International Cancer Control (UICC), with support from the Clean Air Fund, has released a global report, Clean air in cancer control: An overview of the evidence, presenting data on the scale of cancer risk and mortality from polluted air.

Multimodal AI improves prediction of PIK3CA mutations in breast cancer

Breast cancer is one of the most common malignancies worldwide, and mutations in the PI3K/AKT/mTOR (PAM) signaling pathway are prevalent in its development.

AI improves imaging pathology and treatment decisions in breast cancer

Breast cancer is the most common cancer among women, with over 2.3 million new cases diagnosed each year. Traditional diagnostic methods rely heavily on human judgment, which can lead to inconsistent outcomes.

Targeting glutamine metabolism enhances CAR-macrophage cancer therapy

Tumor-associated macrophages (TAMs) within the tumor microenvironment (TME) exhibit significant metabolic dysregulation, which impairs their antitumor function.

Metastatic cells can be identified within primary breast tumors

Understanding which cells within a tumor will go on to form metastases remains one of the major challenges in cancer research.

Generative AI may help scientists connect the many layers of cancer

A Cell Perspective argues that generative AI models could help tackle cancer’s multiscale, multimodal complexity by complementing the Hallmarks of Cancer framework. It proposes that models capable of complex pattern recognition, multimodal fusion, and contextual reasoning could improve cancer detection, biological discovery, and precision oncology, while still requiring rigorous validation and human oversight.

ACP recommends biennial mammography for women aged 50 to 74

New guidance from the American College of Physicians (ACP) says all asymptomatic, average-risk females ages 50 to 74 should receive biennial screening mammography for breast cancer.

New imager separates UV and infrared light to find cancerous nodes

Researchers have developed a compact camera that captures ultraviolet, near-infrared and visible images using a single chip. Inspired by the multiwavelength vision capability of the mantis shrimp, the camera could help surgeons identify lymph nodes connected to a tumor and assess whether cancer has spread to them, making cancer surgery safer and less invasive.

Scientists discover BRCA links to head and neck cancer risks

An international group led by researchers from the RIKEN Center for Integrative Medical Sciences (IMS) in Japan have discovered associations between pathogenic variants of the BRCA 1 and 2 genes and four types of cancer. Published in ESMO Open, the findings expand the potential for personalized medicine to several cancer types that currently have limited treatment options and poor prognoses.
