Radiation therapy is an essential component of the local management of breast cancer. The overview from the Early Breast Cancer Trialists’ Collaborative Group ( 1 ) indicates that adjuvant radiation therapy after breast-conserving surgery results...

Advances in radiation therapy for cancer are reviewed, with emphasis on TomoTherapy® Hi•Art,® a new system for delivering therapy with a helical delivery system in which the patient and the radiation source move in a manner similar to that used for diagnostic CT scans. Simultaneously, the intensity of the radiation beam is modulated by a computer controlled mechanism. The Lancaster General Canc...

Several hotspots of FRII radio sources have previously been detected in the X-ray at a flux level consistent with the X-rays being due to inverse-Compton scattering of radio “synchrotron photons synchrotron self-Compton”, if the magnetic fields in the hotspots are close to their equipartition values. However, the number of hotspots compact and bright enough to exhibit detectable X-ray emission ...

The IARC Working Group classified "Radiofrequency Electromagnetic Fields" (RFEMF) as possibly carcinogenic to humans (Group 2B). The information that formed the main basis for this evaluation was found in epidemiological studies on cell-phone use, where a slightly increased risk for glioma (a malignant form of brain cancer) and acoustic neuroma (a non-cancerous type) was reported among heavy us...

Martin Fuss, M.D. , remembers the old days when radiologists treated a large area to get at a small tumor. Back then, the bone-encased male prostate seemed like an immovable object, recalled Fuss, who directs the imageguided radiation therapy department at the Oregon Health Sciences University in Portland. But advanced imaging technology now makes it possible to spot the slightest movement, he ...
