Study leader, Professor John Mathews from the University of Melbourne said this small increase in cancer risk must be weighed against the undoubted benefits from CT scans in diagnosing and monitoring disease. http://medicalxpress.com/news/2013-05-small-cancer-ct-scans-childhood_1.html Cancer Wed, 22 May 2013 09:22:50 EST news288433364 The estimated size of chest lymph nodes and lung nodules seen on CT images varies significantly when the same nodes or nodules are examined using lower versus higher doses of radiation, a new study shows. The size of lymph nodes and lung nodules is an important determinant of treatment and treatment success. http://medicalxpress.com/news/2013-04-dose-affects-size-lesions-chest.html Cancer Wed, 17 Apr 2013 00:00:02 EST news285354233 Women treated with radiation for breast cancer are more likely to develop heart problems later, even with the lower doses used today, new research suggests. The risk comes from any amount of radiation, starts five years after treatment and lasts for decades, doctors in the UK found. http://medicalxpress.com/news/2013-03-breast-cancer-hearts.html Cardiology Wed, 13 Mar 2013 18:34:21 EST news282418454 Diffusion abnormality index (DAI) shows promise as an imaging biomarker to measure brain tumor response to radiation therapy, according to research being presented at the 2013 Cancer Imaging and Radiation Therapy Symposium.

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. http://medicalxpress.com/news/2012-11-chernobyl-cleanup-workers-significantly-leukemia.html Cancer Thu, 08 Nov 2012 02:46:12 EST news271565113 heralded for its low complication rates—actually results in more complications than whole-breast radiation one year after treatment, Yale School of Medicine researchers report in the October issue of the Journal of Clinical Oncology. http://medicalxpress.com/news/2012-10-older-breast-cancer-patients-complications.html Cancer Mon, 22 Oct 2012 16:00:04 EST news270136740 A recent Phase I/II clinical trial has shown that a new combination of radiation therapies developed at Virginia Commonwealth University Massey Cancer Center escalates radiation doses to safely and effectively treat prostate cancer and lower the risk of recurrence with minimal radiation exposure to nearby healthy tissue and organs. http://medicalxpress.com/news/2012-06-therapy-safely-prostate-cancer-lowers.html Cancer Tue, 26 Jun 2012 17:41:21 EST news259951274 (Medical Xpress) -- A small but statistically significant link between risk of childhood leukaemia and the gamma rays we are all exposed to from our natural environment has been detected in a very large study led by Oxford University researchers. http://medicalxpress.com/news/2012-06-gamma-rays-background-linked-childhood.html Cancer Tue, 12 Jun 2012 09:41:38 EST news258712674 (HealthDay) -- Girls who receive radiation to the chest to treat childhood cancer, even those getting lower doses, have a high risk of developing breast cancer at a young age, according to a new study. http://medicalxpress.com/news/2012-06-chest-girls-greater-early-breast.html Cancer Mon, 04 Jun 2012 09:12:21 EST news258019931 In a Comment linked to The Lancet Physics Series, Dr Ahmed Meghzifene (Division of Human Health, International Atomic Energy Agency, Vienna, Austria) cautions that only physicists with the correct clinical training should be allowed to work in hospitals, in order to avoid dangerous and fatal mistakes.

In a subtype of the disease called extranodal lymphoma, tumors arise in non-lymphoid organs, such as the tongue and tonsils. Patients with extranodal lymphoma of the head and neck often undergo radiation therapy, but this treatment frequently damages the salivary glands and causes dry mouth, which can lead to problems with eating, speaking and swallowing. http://medicalxpress.com/news/2011-08-imrt-outcomes-patients-extranodal-lymphoma.html Cancer Mon, 15 Aug 2011 04:15:22 EST news232600508
