Higher BMI raises risk for 19 cancers as global review expands the obesity-cancer link

A major systematic review and meta-analysis links higher BMI to increased risk of 19 cancer types, including leukemia, non-Hodgkin lymphoma, bladder cancer, and glioma, which were not previously recognized in major consensus reports. The study also reveals regional and sex-based variation in cancer risk, with genetic evidence generally supporting many observational links while highlighting the need for more diverse global cohorts.

Hormone cycles dictate how the brain absorbs neuroprotective drugs

Consider what we ask of a clinical trial. We gather people who differ in nearly every way that matters, we give them the same drug at the same dose, and then we average the result and call the average truth.

Study maps biological pathways of weed killer during pregnancy

Exposure to glyphosate, the active ingredient in many weed killers, was linked to changes in several hormones that support pregnancy and fetal development-in one of the few studies to examine how a widely used herbicide may affect the body during pregnancy. The results come from a new study led by University of Michigan School of Public Health researchers.

Fluctuating hormones during menopause reshape brain activity patterns

Research at the Robert Larner, M.D. College of Medicine at the University of Vermont reveals how menopause, once a taboo topic, affects brain function, reinforcing the idea that the menopause transition is not only a reproductive milestone, but also a critical neurological phase.

Study links menstrual cycle timing to COVID vaccine side effects

A study of 1,474 Clue app users found that women vaccinated against COVID-19 during the follicular phase had higher odds of self-reported side effects than those vaccinated during the luteal phase.

Brain-targeted estrogen reduces breast cancer treatment side effects

Most breast cancers are worsened by estrogens. To combat the recurrence of these cancers, clinicians treat patients with inhibitors for estrogen production, like letrozole. But many patients do not adhere to this treatment due to negative side effects.

Wearable devices may help detect menstrual health changes earlier

Digital health tools, including wearables, provide critical data on menstrual health, enhancing understanding of hormonal fluctuations and women's well-being.

Why blood pressure rises faster in women after midlife

This review examines how sex-specific blood pressure trajectories are shaped by genetics, hormones, metabolic risk factors, lifestyle exposures, environmental stressors, and medical treatments. It highlights that women generally have lower blood pressure earlier in life but may experience steeper increases with aging, especially around and after menopause, with exogenous stressors appearing to have a greater impact in women than in men.

Tomato-soy juice curbs inflammation in obese adults

Drinking tomato-soy juice loaded with compounds shown in animal studies to promote health lowered pro-inflammatory proteins in healthy adults with obesity after four weeks, a new study found.

Estrogen decline alters brain cell matrix in older females

A largely overlooked space between cells in women's brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study.

Perimenopause nearly doubles women’s odds of poor heart health

Perimenopause is linked to worsening cardiovascular health, with significant declines in lipid and glucose scores, emphasizing the need for early assessment.

Perimenopausal women face higher risk of low heart health

Perimenopausal women were two times more likely to have a low cardiovascular health score compared to women having regular menstrual cycles, according to an analysis of nationwide U.S. data published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

New study reveals how slow-growing cells drive breast cancer relapse

A new study by the Garvan Institute of Medical Research has uncovered a hidden mechanism explaining why breast cancer can return many years after successful treatment.

Study challenges assumptions about testosterone’s role in brain cancer

Scientists have long suspected that androgens, male sex hormones like testosterone, may help tumors grow because the hormones can suppress immune responses to some cancers.

Muscle fat levels on MRI linked to cardiometabolic risk

Using a deep learning model to analyze the composition of large muscles on MRI, German researchers found that the proportions of intermuscular fat and lean muscle mass were associated with high blood pressure and unhealthy lipid and blood sugar levels.

Baylor researchers develop SAMENT method to map metastatic tumor niches

Researchers at Baylor College of Medicine and collaborating institutions developed a method that reveals the cellular makeup of tissues that support metastatic cancer growth, which is the primary cause of death for most patients with solid tumors.

Estrogen loss after menopause impacts heart health through gene regulation

Virginia Tech scientists at the Fralin Biomedical Research Institute say the increased risk of cardiovascular disease after menopause may stem not only from declining hormone levels, but also from how those changes influence gene activity.
