Oncologic Surgery

Oncology Surgery is Surgical Treatment for Cancer.

Major progress has been made in treating cancer with combinations of treatment modalities including surgery, chemotherapy and radiation therapy.  Oncology patients treated surgically may be referred for additional non-surgical treatments to complete a comprehensive regimen in order to optimize the prognosis for a pet.

At the MVMC treatment of tumors and cancer that include surgical intervention require evaluating such as tumor type, location, size, and the total health of the patient.

Surgical Removal of Tumors Can be Relatively Standard to Extremely Complex. 

The purpose of surgical oncology is to remove all the cancerous tissue while preserving the function and cosmesis of the patient.  Treatment of tumors in dogs and cats can often be challenging for veterinarians.  Tumors can grow and be found in any part of the body, and can be microscopic in size to large visible masses with extensive soft tissue and/or bone involvement.  Tumors can range from benign to malignant and from slow to aggressive in growth.  Benign tumors are growths that do not invade tissues or spread to other parts of the body.

Often, benign tumors can be completely cured by surgical intervention.  Malignant tumors are locally aggressive and tend to spread to other parts of the body ( metastasize) or recur.  Many cancers can be very well controlled when appropriate surgical techniques are utilized.
