Varian Medical Systems Inc. this week announced that the company has entered into an agreement with Onco Inc. to offer OncoLog and Case Finding, Onco's cancer registry software products, to users of Varian's Oncology Information System for managing radiation and medical oncology clinics.
   
Cancer registry software is helpful due to its ability to automate data collection for state and national cancer registries, and helps clinics identify trends and can track the effectiveness of different treatments.
