Neurofibromatosis-1 may increase risk of breast cancer in women

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.

High CT utilization could increase risk of breast cancer for certain women

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.

Mayo Clinic receives FDA approval for Choline C 11 Injection to help detect prostate cancer

Mayo Clinic has received U.S. Food and Drug Administration approval to produce and administer Choline C 11 Injection, an imaging agent used during a positron emission tomography (PET) scan to help detect sites of recurrent prostate cancer. Mayo Clinic is the first, and currently only, institution in North America approved to produce this imaging agent.

Study reveals increased risk of leukemia among Chernobyl cleanup workers

A 20-year study following 110,645 workers who helped clean up after the 1986 Chernobyl nuclear power plant accident in the former Soviet territory of Ukraine shows that the workers share a significant increased risk of developing leukemia. The results may help scientists better define cancer risk associated with low doses of radiation from medical diagnostic radiation procedures such as computed tomography scans and other sources.

Imaging Healthcare Specialists implements successful radiation dose reduction program

According to an article in the November issue of the Journal of the American College of Radiology, a medical imaging facility in San Diego, Imaging Healthcare Specialists, has implemented a successful radiation dose reduction program, reducing radiation exposure by up to 90 percent in some patients.

Blistering sunburns and working outdoors associated with two nonmelanoma skin cancers

Researchers at Moffitt Cancer Center, the University of South Florida and the International Agency for Research on Cancer in France have studied the patterns and timing of sunlight exposure and how each is related to two nonmelanoma skin cancers - basal cell carcinoma and squamous cell carcinoma.

X-ray technology improves early detection of pulmonary disease

Chronic obstructive pulmonary disease (COPD) is considered the fourth most common cause of death in the United States. Usually the precursor to this life-threatening lung disease is a chronic bronchitis. Partially destroyed alveoli and an over-inflation of the lungs, known as emphysema, are serious side effects. However, the subtle differences in the tissue are barely discernable in standard X-ray images.

Research may lead to new ways to identify women with breast cancer risks from low-dose radiation

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have identified tissue mechanisms that may influence a woman's susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

Quinic acid derivative shows promise for treating radiation exposure

A quinic acid derivative, known as KZ-41, increases 30-day survival threefold compared with placebo when given to rats 24 hours after exposure to high levels of radiation.

Novel drug increases survival in animal models exposed to high-dose radiation

A novel drug that mimics a naturally occurring molecule found in coffee and blueberries has been developed to treat radiation exposure. Charles R. Yates, Pharm.D., Ph.D., and colleagues Duane Miller, Ph.D., and Waleed Gaber, Ph.D., from the University of Tennessee Health Science Center and Baylor College of Medicine, show that application of this drug, starting 24 hours after radiation exposure, increases survival in animal models by three-fold compared to placebo.

AIUM to host Ultrasound First Forum on Nov. 12

The American Institute of Ultrasound in Medicine (AIUM) will host an Ultrasound First Forum on November 12, 2012, in New York, New York. The forum will address the expanding role of ultrasound imaging as a "first" imaging examination and will be devoted to encouraging the use of ultrasound as a safe, effective, and affordable alternative to other diagnostic imaging modalities where scientific evidence supports its appropriateness.
