Masses are lumps that form when cells in the body grow abnormally. Some are benign (non-cancerous), while others are malignant (cancerous). A mast cell tumor is an example of a malignant mass that forms on or under the skin. Benign masses include lipomas. These are fatty tumors that form under the surface of the skin.
Depending on the type and location of a mass, your veterinarian may recommend surgical removal to prevent serious and potentially life-threatening health problems. In this fact sheet, we’ll look at the process of mass removal in pets.
Preparing for Mass Removal Surgery
Most cases of mass removal will require a general anesthetic, although local anesthetic may be adequate for the removal of small masses on the skin. Before performing mass removal surgery, your veterinarian will carry out tests to assess your pet’s overall condition and ensure they are healthy enough to undergo anesthesia.
Post-procedure tests may include bloodwork, a urinalysis, and a complete blood count. Fine-Needle aspiration may also be performed to determine the contents of the mass prior to surgery. In this technique, a thin needle is inserted into the mass to collect a sample of cells.
In addition, imaging techniques such as X-rays and ultrasounds may be performed to check whether the mass has spread to other parts of the body. Your pet will then be placed under general or local anesthesia in preparation for surgery. After your pet is positioned on the operating table, the surgical site will be shaved and disinfected.
Mass Removal Procedure
The exact surgical procedure will depend on the area in which the mass is located. However, in all cases, the aim of surgery will be to remove the mass and an area of surrounding tissue.
During the procedure, your pet will be closely monitored and their vital signs will be measured. After the mass has been surgically removed, your pet’s incisions will be closed with sutures. The mass will usually be sent away for laboratory analysis to determine its contents.
Postoperative Care
Following surgery, analgesics will be prescribed to help manage your pet’s pain. Antibiotics may also be given if an infection is present. A short period of hospitalization may be necessary to monitor your pet and aid their recovery.
Please follow your veterinarian’s treatment advice closely and administer all medications as instructed. It is also important to limit your pet’s activity during the healing process. Consult with your veterinarian immediately if your pet displays signs such as swelling, bleeding, or discharge following surgery.
