VA researcher finds way to identify which men need a second biopsy
A researcher in the Oregon Health & Science University Cancer Institute and Portland Veterans Affairs Medical Center has found a way to identify which men need a second prostate biopsy because they may be harboring life-threatening prostate cancer even though they were given a clean bill of health after their first biopsy. view more (2007-02-23)
Researcher: 'Optical biopsy' for breast cancer increasingly accurate
But women may not have to endure the medical costs, stress and potential complications that accompany such invasive biopsies forever. A University of Florida biomedical engineering researcher is making progress on an "optical biopsy" that has the potential to determine whether growths are cancerous without ever puncturing the skin. view more (2009-11-06)
Nanoscopic changes to pancreatic cells reveal cancer
A team of researchers in Chicago has developed a way to examine cell biopsies and detect never-before-seen signs of early-stage pancreatic cancer, according to a new paper in the Optical Society (OSA) journal Optics Letters. view more (2009-02-13)
Prostate cancer gene test provides new early detection
Prostate cancer (PCa) is one of the most common male cancers in the Western world. Currently, early detection of PCa depends on an abnormal digital rectal examination and an elevated prostate-specific-antigen (PSA) level requiring a prostate biopsy, often associated with anxiety, discomfort, complications, and heavy expenses. view more (2008-10-17)
First calves from gene diagnosed embryos born at MTT Agrifood Research Finland
Results from quantitative trait gene mapping (QTL) have been utilised for the first time in the selection of bovine embryos. The genotypes of two genes affecting milk yield and composition have been analysed from pre-implantation embryo biopsies. The first four female calves with known milk production genotypes were recently born at the... view more... (2003-08-14)
Mayo Clinic's new imaging technology accurately identifies a broad spectrum of liver disease
A new study shows that an imaging technology developed by Mayo Clinic researchers can identify liver fibrosis with high accuracy and help eliminate the need for liver biopsies. Liver fibrosis is a common condition that can lead to incurable cirrhosis if not treated in time. view more (2008-11-03)
Vitamin E, selenium and soy in combination does not prevent prostate cancer
The combination therapy of vitamin E, selenium and soy does not prevent the progression from high-grade prostatic intraepithelial neoplasia (HGPIN) to prostate cancer, according to the new research presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA). view more (2009-04-27)
New blood test greatly reduces false-positives in prostate cancer screening
A new blood test used in combination with a conventional prostate-specific antigen (PSA) screening sharply increases the accuracy of prostate cancer diagnosis, and could eliminate tens of thousands of unneeded, painful, and costly prostate biopsies annually, according to a study led by researchers at Dana-Farber Cancer Institute. view more (2009-05-29)
OHSU Cancer Institute, VA researchers find way to identify which men need a second biopsy
A researcher in the Oregon Health & Science University Cancer Institute and Portland Veterans Affairs Medical Center has found a way to identify which men need a second prostate biopsy because they may be harboring life-threatening prostate cancer even though they were given a clean bill of health after their first biopsy. view more (2007-06-04)
Surgeons' unanimous consensus: Needle biopsy is gold standard for breast cancer diagnosis
A special report published in the October issue of the Journal of the American College of Surgeons indicates that an alarming 35% of initial diagnostic breast biopsies in the United States are still being done using unnecessary open surgical techniques. view more (2009-10-07)
Non-invasive diagnostic tools for assessment of function and structure of the stomach mucosa
Risks for gastric cancer or peptic ulcer diseases are low in subjects with healthy stomach mucosa but are remarkably high in those with "diseased" stomach mucosa: i.e., in those with H pylori gastritis or atrophic gastritis. view more (2009-02-23)
Barrow study identifies new way to biopsy brain tumors in real time
A new miniature, hand-held microscope may allow more precise removal of brain tumors and an easier recognition of tumor locations during surgery. view more (2009-11-12)
Clues to the cause of difficulty with swallowing in children
Eosinophilic esophagitis (EE) is disease that was first described in children only 20 years ago, but has shown a rising incidence in both children and adults. view more (2007-01-19)
Mayo Clinic Study Finds Risk Assessment Tool Not Reliable Predictor for Some Women at High Risk of Breast Cancer
A statistical model commonly used to predict the risk of breast cancer in women was not accurate when used to evaluate women with atypical hyperplasia, according to a new Mayo Clinic study published in the Oct. 14, 2008, issue of the Journal of Clinical Oncology. view more (2008-11-06)
Researchers find two biomarkers with potential to predict breast cancer spread
Expression of two different proteins taken from primary tumor biopsies is highly associated with spread of breast cancer to nearby lymph nodes, according to researchers who say this protein profile could help identify at an early stage those patients whose disease is likely to metastasize. view more (2006-12-18)
PneuStep — MRI-safe motor makes robotic biopsies possible
Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging. view more (2007-04-09)
COX-2 expression is marker for cancer development in some benign breast biopsies
It's a good news, bad news situation. Some women who have a breast biopsy are told that while they don't have cancer, they do have atypical hyperplasia -- cells that aren't quite normal and might become cancerous someday. This happens to one-fourth of women undergoing breast biopsies but no one knows which individuals are at risk. view more (2008-03-12)
How to confirm the causes of iron deficiency anemia in young women
Iron-deficiency anaemia (IDA) is commonly seen in women aged <50 years. The diagnostic workflow in young women affected by IDA is not clearly established. view more (2009-06-24)
Core needle biopsy gives an accurate picture of gene expression in whole tumor
The gene expression profile detected in the core needle biopsy of a breast tumour is representative of gene expression in the whole tumour. view more (2006-08-21)
Scientists learn why even treated genital herpes sores boost the risk of HIV infection
New research helps explain why infection with herpes simplex virus-2 (HSV-2), which causes genital herpes, increases the risk for HIV infection even after successful treatment heals the genital skin sores and breaks that often result from HSV-2. view more (2009-08-03)
