Cancer Care

If cancer is your diagnosis, it’s important to be confident in your treatment plan. At Prevea, you are in the best of hands.

Customized cancer care from a customized team: Our surgical team works hand-in-hand with the HSHS St. Vincent Cancer Centers and other specialties you may need during your journey. They include experts in imaging, medical oncology, radiation oncology, cancer navigators, genetics, rehab and behavioral health. 

Tumor Board review of every tumor: The most complex cancer cases are brought in front of a group of local cancer experts who determine the best treatment plan for every patient. This group uses national best practices and data from clinical trials to guide their decisions.
