Early breast cancer may be detected through breath, urine tests

New utilization of breath and urine tests may be able to screen for early stage breast cancer — the most commonly diagnosed cancer among women in the world. Breast cancer biomarkers were accurately detected in a new study by researchers at Ben-Gurion University by using two "nose gas" sensors on breath and gas-chromatography mass spectrometry (GC-MS) — a method of testing substances found in urine. "Breast cancer survival is strongly tied to the sensitivity of tumor detection," co-author of the study, Yehuda Zeiri said in a release. "Accurate methods for detecting smaller, earlier tumors remains a priority (and) our new approach utilizing urine and exhaled breath samples, analyzed with inexp

Following a couple from diagnosis to the final stages of Alzheimer's

For 10 years, Dr. Jon LaPook has been checking in on Carol Daly, a woman diagnosed with Alzheimer's, and her caregiver husband, Mike. After a decade, the disease has had a devastating impact on each of them. Mike and Carol Daly have been married for 53 years. Like more than five million American families, they're dealing with dementia. Carol has been suffering from Alzheimer's, the main type of dementia. What makes this story so unusual is that almost every year for the past 10 years we've interviewed Mike and Carol as Alzheimer's took over her brain. Even though this is intensely personal, they wanted all of us to see the devastating impact of Alzheimer's, on each of them, over a decade. To

THIS NEW TECHY BRA MIGHT BE ABLE TO DIAGNOSE BREAST CANCER

Performing regular self-exams is a must when it comes to protecting yourself against breast cancer. And in recent years, the public market has been flooded with techy innovations designed to help better monitor health. One of the most recent examples is a (super-cute!) bra that actually screens women for breast cancer—but could it be too good to be true (i.e., is it effective)? Julián Ríos Cantú—whose mother was diagnosed with breast cancer when he was 13 years old—joined forces with three friends to create a product to keep other women from being in the situation his mom endured: discovering cancer late, and almost dying because of it. Now, at 19, the teen’s vision has come to life with EVA

In Polluted Cities, Kids Show Hallmarks of Alzheimer’s Disease

Alzheimer’s disease may get a very early start in people living in polluted megacities, according to a new study published in the Journal of Environmental Research. The University of Montana (UM) researchers detected early stages of the disease in babies less than a year old. The researchers believe that the harmful effects begin when tiny pollution particles enter the brain through the nose, lungs and gastrointestinal tract; these particles then proceed to damage all barriers and travel throughout the body via the circulatory system. For the study, the research team studied 203 autopsies of Mexico City residents between the ages of 11 months and 40 years. Mexico City is home to 24 million p

Identifying the Optimal Breast Cancer Screening Interval

A meta-analysis of data from randomized clinical trials into breast cancer screening showed that women aged 50 to 70 years invited to screening had a 20% lower risk for breast cancer–related death.1 Despite this and other evidence, it is unclear whether breast cancer screening — and specifically mammography — reduces the likelihood of being diagnosed with advanced-stage disease. “One of the main criticisms of breast cancer screening is that it does not have an effect on lowering the incidence of advanced-stage disease in the total population, usually based on registry data,” explained Linda de Munck, MSc, of the Netherlands Comprehensive Cancer Organisation. “However, if no information is av

Blood test detects Alzheimer's before symptoms appear

One of the major issues that hamper Alzheimer's research is that the disease is always caught at a relatively late stage. This is because symptoms develop slowly over a number of years; they become obvious long after the condition has made changes in the brain. As it stands, there are no simple ways to detect whether Alzheimer's disease is developing in an individual. The only reliable methods of diagnosis are positron emission tomography (PET) brain scans, which are time-consuming and expensive, and the analysis of cerebrospinal fluid (CSF) collected by a lumbar puncture, which is painful and invasive. A study, published in the journal EMBO Molecular Medicine, describes a potential solution

New Method Combines X-rays with Harmless Red Light for Improved Breast Cancer Diagnosis

A new advance in optical mammography, coupling harmless red or infrared light with X-rays, increases the sensitivity of the approach for breast cancer diagnosis and monitoring by up to 1,000 times, researchers say. Italian researchers introduced the innovative device at the OSA Biophotonics Congress: Biomedical Optics meeting, held April 3-6 in Hollywood, Florida. The majority of breast cancer diagnoses are made with X-ray mammography, but this method has limited sensitivity — only 50 to 75 percent of patients with a breast tumor are correctly identified as such — and because it uses ionizing radiation, it’s not without risk. X-ray mammography is also limited by factors such as a patient’s a

Low dopamine may indicate early Alzheimer's

Dopamine is a neurotransmitter that is involved in regulating emotional responses and movement. The new study shows that the loss of cells that use dopamine could impair function in brain regions that create new memories. The results of the study were recently published in the Journal of Alzheimer's Disease. Its authors believe that this finding has the potential to transform the way in which Alzheimer's is diagnosed.
