Study Reveals Huge Genetic Diversity In Cells Shed By Tumors
5/08/2012
The cells that slough off from a cancerous tumor into the bloodstream are a genetically diverse bunch, Stanford University School of Medicine researchers have found. Some have genes turned on that give them the potential to lodge themselves in new places, helping a cancer spread between organs...
Curry Ingredient May Have Cancer Treatment Benefits
5/08/2012
New evidence, studied by researchers in the Department of Cancer Studies and Molecular Medicine, at the University of Leicester, reveals that curcumin, found in the curry ingredient turmeric, may significantly reduce side effects for bowel cancer patients undergoing chemotherapy and help them to be able to go through treatment longer...
Ancient Remedy Slows Prostate Tumor Cell Proliferation
5/08/2012
An over-the-counter natural remedy derived from honeybee hives arrests the growth of prostate cancer cells and tumors in mice, according to a new paper from researchers at the University of Chicago Medicine. Caffeic acid phenethyl ester, or CAPE, is a compound isolated from honeybee hive propolis, the resin used by bees to patch up holes in hives...
Blacks and Hispanics have a significantly higher risk of developing precancerous colorectal polyps compared with whites, according to a study by researchers at NewYork - Presbyterian Hospital/Columbia University Medical Center. The findings appeared in the online edition of Alimentary Pharmacology and Therapeutics...
Researchers Search 'Junk' DNA For Colorectal Cancer Clues
5/08/2012
Two researchers at the Geisel School of Medicine at Dartmouth have helped to identify switches that can turn on or off genes associated with colorectal cancer. The finding offers clues about the development of colorectal cancer and could - potentially - provide targets for new therapies...
HPV Vaccine Completion Rate Among Girls Is Poor, Getting Worse
5/08/2012
The proportion of insured girls and young women completing the human papillomavirus (HPV) vaccine among those who initiated the series has dropped significantly - as much as 63 percent - since the vaccine was approved in 2006, according to new research from the University of Texas Medical Branch (UTMB) in Galveston...
Fibroid Tumors Triggered By A Single Stem Cell Mutation
5/08/2012
Fibroid uterine tumors affect an estimated 15 million women in the United States, causing irregular bleeding, anemia, pain and infertility. Despite the high prevalence of the tumors, which occur in 60 percent of women by age 45, the molecular cause has been unknown...
How Does A Broken DNA Molecule Get Repaired?
5/08/2012
Scientists from the Kavli Institute of Nanoscience at Delft University of Technology have discovered a key element in the mechanism of DNA repair. When the DNA double helix breaks, the broken end goes searching for the similar sequence and uses that as a template for repair...
Hypoxia Could Drive Cancer Growth
5/08/2012
Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth...
Questioning The Necessity Of 6 Month Follow-Up Of Patients With Benign MRI-Guided Breast Biopsies
5/08/2012
Short term follow-up of patients who have had a negative (benign) MRI-guided vacuum assisted breast biopsy may not be necessary, a new study indicates. The study, conducted at Yale New Haven Hospital in Connecticut, included 144 patients with 176 lesions that were followed anywhere from three months to 36 months...
