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.

Eating more plant-based foods may lower breast cancer risk, major international study indicates

Greater adherence to healthful plant-based dietary patterns was associated with lower breast cancer incidence and reduced all-cause mortality among women with breast cancer in large prospective cohorts. Specific micronutrients showed differential associations with cancer risk and survival, though findings remain observational and not causal.

Time of radiotherapy influences cancer treatment response

A team of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER) and the University of Seville, in collaboration with the Virgen Macarena University Hospital, have identified a fundamental mechanism that links the 24-hour circadian cycle to the precise repair of DNA breaks.

Nanovaccine design boosts immune attack on HPV tumors

Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure.

Tiny organism offers insight into neurological side effects of chemotherapy

Chemotherapy remains one of the most powerful tools in the fight against cancer, yet it often comes with significant long-term side effects that can dramatically affect patients' quality of life.

Prior abortion or miscarriage not linked to increased risk of pre- or postmenopausal breast cancer

A prior abortion or miscarriage was not linked with an increased risk of developing pre- or postmenopausal breast cancer in a study published in Acta Obstetricia et Gynecologica Scandinavica.

DNA barcoding can be used to track cancer cells in solid and liquid biopsies

Australian scientists have discovered that DNA barcoding can be used to track cancer cells in solid and liquid biopsies, empowering future research into more reliable breast cancer diagnosis and treatment strategies.

Global report highlights inequities in pediatric palliative care

Nearly all the world's 10.6 million children experiencing serious health-related suffering (SHS) live in low- and middle-income countries with little to no access to palliative care specialized care for their illness, according to a comprehensive new report published in The Lancet Child & Adolescent Health.

US cancer institute studying ivermectin’s ‘ability to kill cancer cells’

The National Cancer Institute, the federal research agency charged with leading the war against the nation's second-largest killer, is studying ivermectin as a potential cancer treatment, according to its top official.

Historical redlining's impact on breast cancer survival changes over time

Historical redlining, a 1930s–1960s residential segregation policy, has been linked to shorter survival time in people with breast cancer.

Mesothelial cells enable rapid invasion and spread of ovarian cancer

Ovarian cancer kills more women than any other gynecological cancer. Most patients receive their diagnosis only after the disease spreads throughout the abdomen.

Cholesterol transporter ABCA1 boosts macrophage-driven cancer immunity

In recent years, cancer researchers have made major breakthroughs by using the body's immune system to fight cancer. One of the most promising approaches, known as immune checkpoint blockade, works by releasing molecular "brakes" on T cells.

Triple negative breast cancer cells use new strategy to boost metastatic ability

Researchers at Baylor College of Medicine have uncovered a strategy that triple negative breast cancer (TNBC) cells use to boost their ability to metastasize, or spread to other organs.

Early biomarkers predict infections after breast reconstruction surgery

In the U.S., one in eight women will get breast cancer in their lifetime, and about half of them will have mastectomies.

Early pregnancy reshapes breast aging and lowers cancer risk

A new study by cell biologists at the University of California, Santa Cruz, suggests that an early first pregnancy may protect against breast cancer decades later by preventing age-related changes in breast cells that are linked to tumor formation.

Cardiologists highlight overlooked heart risks across women’s lives

Heart disease remains the leading cause of death for women in the United States, yet awareness of cardiovascular risk—particularly among younger women and women of color—has stalled, even as rates of high blood pressure, diabetes, obesity, and high cholesterol continue to rise.

NIH grant disruptions slow down breast cancer research

Inside a cancer research laboratory on the campus of Harvard Medical School, two dozen small jars with pink plastic lids sat on a metal counter. Inside these humble-looking jars is the core of Joan Brugge's current multiyear research project.

Most commercially insured patients live with chronic conditions

The majority (57.5 percent) of commercially insured patients had at least one chronic condition in 2024. The average allowed amount for a patient with no chronic conditions was $1,590, while the average allowed amount for a patient with one chronic condition was nearly double ($3,039).

New liquid biopsy detects early cancers through epigenetic instability

Researchers at the Johns Hopkins Kimmel Cancer Center have developed a novel liquid biopsy approach to identify early-stage cancers by measuring the random variation in DNA methylation patterns, rather than the absolute level of those patterns as in other liquid biopsies.

Miniaturized ultrasound system may enable earlier detection of breast cancer

For people who are at high risk of developing breast cancer, frequent screenings with ultrasound can help detect tumors early. MIT researchers have now developed a miniaturized ultrasound system that could make it easier for breast ultrasounds to be performed more often, either at home or at a doctor's office.
