19% of women don't receive recommended radiation after mastectomy
One-fifth of women who should receive radiation after a mastectomy are not getting this potentially lifesaving treatment, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.   view more (2009-02-04)

Cosmic radiation associated with risk of cataract in airline pilots
Airline pilots have an increased risk of nuclear cataracts-common type of cataract, associated with aging-compared with non-pilots, and that risk is associated with cumulative exposure to cosmic radiation.   view more (2005-08-09)

Study first: Over-expression of Cox-2 can predict prostate cancer outcome
Researchers say an over-expression of COX-2 in men with prostate cancer is associated with an increase in PSA after radiation treatment and the spread of the cancer outside of the prostate.   view more (2006-11-09)

Radiologists Can Dramatically Lower Cardiac CT Radiation Dose in Some Patients
Radiologists can now lower the radiation dose delivered by cardiac CT angiography by 39% in adult patients weighing 185 pounds or less, according to a study performed at the University of Erlangen in Erlangen, Germany.   view more (2009-04-06)

Cancer patients who receive neoadjuvant therapy followed by mastectomy may not need radiation
Early-stage breast cancer patients who exhibit limited lymph node involvement may not require post-surgery radiation therapy (RT) when they receive neoadjuvant chemotherapy before a mastectomy, according to researchers from The University of Texas M. D. Anderson Cancer Center.   view more (2008-09-25)

New radiation technique helps brain cancer patients keep their hair
Patients whose cancer has spread to the brain can avoid typical hair loss (alopecia) when treated with newer radiation techniques, thereby improving their quality of life while still controlling their cancer.   view more (2005-10-17)

Ultraviolet radiation induced flux of nitrogen oxides from pine needles
In the latest edition of Nature (March 13th, 2003) a group of scientist led by professor Pertti Hari from the University of Helsinki presents a novel observation: ultraviolet radiation induced a flux of nitrogen oxides (NOx) from pine needles to the atmosphere. This result is interesting because nitrogen oxides participate in several essential... view more... (2003-03-14)

Guided radiation therapy for prostate cancer prevents damage to surrounding organs
Oregon Health & Science University Cancer Institute researchers have found that highly targeted radiation therapy for prostate cancer can ensure that the majority of persons with this tumor will not have any long-term rectal damage.   view more (2007-10-29)

Women with breast cancer have less dermatitis when treated with IMRT
All women treated with radiation therapy for breast cancer are at risk of developing dermatitis-a sometimes-painful skin condition caused by radiation as it makes its way through the skin to the tumor area and tissue within the breast.   view more (2007-10-29)

University of Toronto study shows climate change will lead to less ultraviolet radiation over northern high latitudes
Physicists at the University of Toronto have discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada.   view more (2009-09-16)

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)

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)

Major surgery no longer needed for the removal of uterine fibroids
The treatment of uterine fibroids with 3T MR-guided focused ultrasound (MRgFUS) is safe, non-invasive and effective, according to a recent study conducted by researchers at Weill Cornell Medical College in New York, NY.   view more (2008-04-14)

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)

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)

MR angiography highly accurate in detecting blocked arteries
A novel type of contrast-enhanced magnetic resonance (MR) angiography is highly accurate in identifying blockages in the arteries that carry blood to the brain, according to a study in the February issue of Radiology.   view more (2007-01-30)
