The Veterinary Society of Surgical Oncology (VSSO) was developed to bring together individuals with various backgrounds but similar goals: to more effectively treat veterinary patients with cancer and to advance the understanding of cancer across species. While much of our focus is placed on the surgical aspects of oncology, we incorporate the principles of other treatment modalities such as chemotherapy, radiation therapy, and interventional oncology, and focus on utilizing evidence-based medicine in our daily practice.
