We will work with your regular veterinarian to coordinate diagnosis of the mass.  This involves taking a sample of the mass through a fine needle aspirate (FNA), sometimes ultrasound guided or a biopsy.  These procedures often require sedation and some require general anesthesia.  This can be done with your regular veterinarian, another veterinary specialist (internist, oncologist), or with us @ VSCP.


If the mass is cancerous we talk about staging-seeing if the cancer has spread (metastasized).  Staging can include aspirates of lymph nodes close to the mass.  Radiographs of the lungs and abdomen to look for cancer, ultrasound of the abdomen, or CT of chest.  The diagnostics chosen depend on the type of cancer.  Staging can be coordinated through your regular veterinarian, another veterinary specialist (internist, oncologist), or with us @ VSCP.


When a mass is removed at VSCP, it is preserved and sent to Colorado State University for a histopathology.  The clinical pathologist diagnosis the mass-often grades it (tells us how aggressive it is) and gives us margins (how much cancer-free tissue surrounds the mass).  All of this information allows us to give you a prognosis for chance of reoccurrence.


Sometimes surgical removal of the mass is curative.  When it is not, we refer you to a veterinary oncologist.  In Portland, your pet can see a medical oncologist (chemotherapy and palliative treatment) or a radiation oncologist.  We will work with your primary veterinarian to help coordinate any referrals.
