Novel radiotherapy approach for lung cancer

A novel radiotherapy approach has shown promise as a treatment option, and may possibly increase the cure rate, for people with early stage lung cancer who are unable to tolerate surgery, according to findings from a five-year study led by SUNY Upstate Medical University.

Cancer risk from radiation during cardiac CT scans studied

An analysis based on computerized simulation models suggests that the lifetime risk of cancer associated with radiation exposure from a computed tomography (CT scan) coronary angiography varies widely, with the risk greater for women and younger patients, according to a study in the July 18 issue of JAMA .

Suped-up computed tomography scanners

By borrowing techniques used in telecommunications technology, computed tomography (CT) scanners may eventually see data collection speeds increase by hundreds of times, leading to better images, faster imaging procedures, and potentially lower x-ray exposures.

Nodal status is best predictor of outcome after neoadjuvant therapy for esophageal cancer

The number of lymph nodes that contain evidence of cancer is the best predictor of the effectiveness of adding chemotherapy and radiation to a treatment plan prior to surgery in individuals with oesophageal cancer, according to a study published last month in the Annals of Surgery.

Magnetic resonance spectroscopy for breast cancer

The American Cancer Society recently issued new recommendations for women with a higher risk of developing breast cancer, including those with a family history of breast or ovarian cancer, and those who may carry genetic mutations (BRCA1 or BRCA2) that make them more likely to develop the disease.
