An organized population-based breast cancer screening program in Norway and an approach to screening that relies on physician- and self-referrals in Vermont are equally sensitive for detecting cancer, scientists report in the July 29 online issue of the Journal of the National Cancer Institute But the recall rate for abnormal mammograms was lower in Norway........
A University of Michigan study reveals in detail how breast cells produce new cells that are predisposed to become malignant, unless they receive the protective action of the CHFR gene. CHFR expression is missing in more than a third of breast cancers. Analysis of this gene is also a hot area of interest among scientists trying to explain colorectal, stomach, lung and other forms of cancer........
Psychological interventions for cancer patients do more than just ease emotional distress - they directly improve health, new research suggests. A study of 227 patients with breast cancer observed that those who participated in a psychological intervention program were rated as having better health by a research nurse a full year after the program started........
Scientists have discovered a new family of agents that inhibit the growth of estrogen-dependent breast cancer cells. The finding, described today at a meeting of the Endocrine Society, has opened an avenue of research into new drugs to combat estrogen-dependent breast cancers. "This cell-based study is exciting because it suggests these compounds are likely to be effective in tumors that remain dependent on estrogen for growth but are resistant to current therapies," said principal investigator David J. Shapiro, a professor of biochemistry in the School of Molecular and Cellular Biology at the University of Illinois........
A new test that examines large sections of the sentinel lymph node for genes expressed by breast cancer could reduce the risk of recurrence and multiple surgeries, doctors say. The GeneSearch Breast Lymph Node Assay, manufactured by Veridex, L.L.C., a Johnson and Johnson company, is being used at the Medical College of Georgia to examine half of the tissue in the sentinel lymph node, the first place breast cancer typically spreads. The sample represents more than 10 times the amount of tissue examined in traditional biopsies........
