Cancer death rates decline, but economic gap remains
January 9, 2019 -- The overall cancer death rate in the U.S. dropped by 27% over the past 25 years, but more needs to be done to reduce deaths among Americans of lower socioeconomic status, according to a report from the American Cancer Society published online January 7 in CA: A Cancer Journal for Clinicians.  Discuss
Beyond BMI: AMRA aims to take MRI fat analysis further
January 9, 2019 -- SAN FRANCISCO - Image analysis software developer AMRA Medical hopes to take body fat analysis beyond the measurement of body mass index (BMI) with an application that analyzes MRI scans to assess health risk, according to a presentation on Tuesday at the Digital Medicine & Medtech (DigiMed) Showcase.  Discuss
What can rad onc residents expect in the job market?
January 9, 2019 -- What can radiation oncology residents expect to find in the job market upon graduation?
