Physiological Evidence Of 'Chemo Brain'
11/28/2012
Chemotherapy can induce changes in the brain that may affect concentration and memory, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA)...
Brain Tumors Nurtured By Metabolic Protein That Launches Sugar Feast
11/28/2012
Researchers at The University of Texas MD Anderson Cancer Center have tracked down a cancer-promoting protein's pathway into the cell nucleus and discovered how, once there, it fires up a glucose metabolism pathway on which brain tumors thrive...
Link Between Gene That Causes Tumor Disorder And Increased Breast Cancer Risk
11/28/2012
New Johns Hopkins research showing a more than four-fold increase in the incidence of breast cancer in women with neurofibromatosis-1 (NF1) adds to growing evidence that women with this rare genetic disorder may benefit from early breast cancer screening with mammograms beginning at age 40, and manual breast exams as early as adolescence...
The Effects Of Mammography Guideline Changes
11/28/2012
Researchers assessing the impact of revised guidelines for screening mammography issued by the U.S. Preventive Services Task Force (USPSTF) found evidence that the new recommendations may lead to missed cancers and a decline in screening, according to two studies presented at the annual meeting of the Radiological Society of North America (RSNA)...
Additional Screening Welcomed By Women With Dense Breasts
11/28/2012
A survey of women undergoing routine screening mammography found that many of them would be interested in pursuing additional screening tests if notified they had dense breast tissue, despite the possibility of false positives, invasive procedures, and out-of-pocket costs, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA)...
Repeated CT And Nuclear Imaging Increases Breast Cancer Risk
11/28/2012
Researchers reviewing the records of approximately 250,000 women enrolled in an integrated healthcare delivery system found that increased CT utilization between 2000 and 2010 could result in an increase in the risk of breast cancer for certain women, including younger patients and those who received repeat exams...
No Cancer Risk From Scatter Radiation During Mammography
11/28/2012
The radiation dose to areas of the body near the breast during mammography is negligible, or very low, and does not result in an increased risk of cancer, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA). The results suggest that the use of thyroid shields during mammography is unnecessary...
New Drug Hope For Ewing Sarcoma
11/28/2012
Discovery of a new drug with high potential to treat Ewing sarcoma, an often deadly cancer of children and young adults, and the previously unknown mechanism behind it, come hand-in-hand in a new study by researchers from Huntsman Cancer Institute (HCI) at the University of Utah. The report appears online in the journal Oncogene...
Helping Cancer Patients To Quit Smoking
11/28/2012
It's a sad but familiar scene near the grounds of many medical campuses: hospital-gowned patients, some toting rolling IV poles, huddled in clumps under bus shelters or warming areas, smoking cigarettes. Smoking causes 30 percent of all cancer deaths and 87 percent of all lung cancer deaths...
New Hope For Setback-Dogged Cancer Treatment
11/28/2012
Several drugs companies have ineffectively tried to produce antibodies that bind to the IGF-1 receptor on the cell surface, which has a critical part to play in the development of cancer. Scientists at Karolinska Institutet in Sweden have now ascertained how these antibodies work, and can explain why only some cancer patients are helped by IGF-1 blockers during clinical tests...
