Advances in digital mammography are evolving as clinicians look to improve breast cancer screening in women. In recent years, new technological trends have emerged; notably, the addition of 3-D breast imaging, or tomosynthesis, which was approved by the U.S. Food and Drug Administration (FDA) in 2011. But as technology improves, questions remain over the recommended frequency of screening for breast cancer.

Increasing research on women with dense breasts is having a positive effect on imaging modalities. It is estimated that between 30–40 percent of women in the United States have dense breasts. Because fatty breast tissue makes it difficult to identify breast tumors on standard mammography exams until very advanced stages, dense breasts are a strong independent factor for breast cancer. Research has shown that it is beneficial for this population of women to invest in additional imaging.

March 13, 2013 — The March 2013 issue of the Journal of Urology includes a study conducted by four physicians from Radiotherapy Clinics of Georgia (RCOG), a Vantage Oncology affiliate. The study, 25 Year Disease Free Survival Rate after Irradiation of Prostate Cancer Calculated with the Prostate Specific Antigen Definition of Recurrence Used for Radical Prostatectomy, is the first to analyze 25 years of follow-up data after radiation therapy treatment for prostate cancer patients.

Atherosclerosis is usually considered to be related to contemporary risk factors such as smoking, obesity and lack of exercise. However, researchers suggest that high prevalence of atherosclerosis in pre-modern humans may support the possibility of a more basic human predisposition to the disease.

Many physicians have long believed that the use of intravenous contrast agents for computed tomography (CT) scans can cause acute kidney injury. New Mayo Clinic research questions the strength of the causal link between the two. The findings from two tandem studies are published online in the journal Radiology.
