Aiming to avoid damage to neurocognitive areas of the brain during cranial radiation
Radiation oncologists at Rush University Medical Center are intent on finding ways to avoid damage to the critically important hippocampus and limbic circuit of the brain when cranial radiation is required to treat existing or potential metastatic cancers. view more (2009-11-04)
Physicists find way to 'see' extra dimensions
Peering backward in time to an instant after the big bang, physicists at the University of Wisconsin-Madison have devised an approach that may help unlock the hidden shapes of alternate dimensions of the universe. view more (2007-02-05)
Radiation heart dose from MammoSite compared to IMRT for left-sided breast cancers
When compared to IMRT, MammoSite Brachytherapy does not always deliver lower doses of radiation to the heart during treatment of left sided breast cancers. view more (2006-11-09)
Preoperative radiation may improve survival rates in advanced rectal cancer patients
Patients treated with radiation prior to surgery for advanced rectal cancer have fewer instances of cancer recurrence and better overall survival rates, according to a recent Geisinger report. view more (2008-12-02)
Smokers have worse side effects from radiation treatment for prostate cancer
Smoking has been found to contribute to poorer outcomes for people treated for many kinds of cancer and now, researchers at Fox Chase Cancer Center have associated smoking and acute side-effects following radiation therapy for prostate cancer. view more (2006-11-06)
Positioning pelvic cancer patients on stomachs for radiation yields better results
Oregon Health & Science University Cancer Institute researchers have found that positioning pelvic cancer patients on their stomachs rather than their backs is a better method for delivering radiation therapy. view more (2007-10-29)
One day radiation may become an option for breast cancer patients
Doctors in Canada are studying the effectiveness of permanent radiation seed implants following lumpectomy as an alternative to whole or partial breast irradiation for early-stage breast cancer patients. view more (2006-01-04)
Where Broken DNA is Repaired
Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer. view more (2007-08-03)
Patient' exposure to radiation significantly lower when using new cardiac CT technique
A new cardiac CT technique, prospective gated 64-channel cardiac CT, has a significantly lower radiation dose and produces CT coronary angiograms with better image quality when compared with the standard retrospective ECG gating. view more (2008-04-14)
Rapidly rising PSA before treatment is key indicator of cancer spread
Results of a new Fox Chase Cancer Center study show that men with a rapidly rising PSA level before treatment have a high probability of metastatic disease and should receive hormone therapy in addition to radiation. view more (2006-11-09)
Researchers study effects of Aricept in pediatric brain cancer survivors
A pediatric oncologist at Brenner Children's Hospital is evaluating whether a drug typically used to treat Alzheimer's patients will help brain cancer survivors avoid the learning and memory problems that are common after radiation therapy. view more (2006-11-06)
Italian, US cosmologists present alternate explanation for accelerating expansion of the universe: Was Einstein right when he said he was wrong?
Why is the universe expanding at an accelerating rate, spreading its contents over ever greater dimensions of space? An original solution to this puzzle, certainly the most fascinating question in modern cosmology, was put forward by four theoretical physicists, Edward W. Kolb of the U.S. Department of Energy's Fermi National Accelerator... view more... (2005-03-16)
Could vitamin D save us from radiation?
Radiological health expert Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene suggests that a form of vitamin D could be one of our body's main protections against damage from low levels of radiation. view more (2008-11-10)
Common aquatic animals show extreme resistance to radiation
Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal species studied to date. view more (2008-03-26)
OU Part of International Study on Genetic Impact of Radiation
Researchers at the University of Oklahoma Health Sciences Center are helping to lead a massive international study on the possible genetic effects of radiation and cancer drug exposures on future generations. view more (2009-10-08)
Angled gantry technique reduced breast radiation exposure by 50 percent
A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers. view more (2008-12-04)
Jefferson oncologists show focused radiation is effective as surgery against nerve tumor
Specifically aimed, "stereotactic" radiation may be as good as surgery - and in some cases, even better - in treating benign but potentially devastating brain tumors called non-acoustic schwannomas. view more (2007-10-31)
Extra radiation dose prevents breast cancer return in young women
Women 40 years and younger with early-stage breast cancer who receive an additional high dose of radiation (boost dose) after undergoing breast-conserving surgery (lumpectomy) and standard radiation treatment are almost twice as likely to be free of cancer 10 years after treatment compared to those who don't receive the boost dose. view more (2007-10-30)
Timing of radiation treatments for colon cancer may need adjusting, Jefferson researchers say
Scientists have unexpectedly discovered that mice with the gene defect that causes colon cancer in humans can differ from normal mice in how they respond to radiation treatments. view more (2006-04-10)
Intravenous chemoradiation effective for inoperable head, neck cancer; easier for patients, doctors
Chemoradiation (radiation and chemotherapy given at the same time) given through a needle or tube inserted into a vein (intravenous) is as effective as treatment given directly to the tumor through a tube inserted into an artery (intra-arterial) for patients with inoperable head and neck cancer. view more (2006-11-07)
