Tumor Removal What is it

What is Tumor Removal Surgery?

Tumor removal surgery means taking out abnormal tissue or masses from the body. The reason for surgery depends on the tumor’s type, size, and location. It may be done to diagnose the problem, treat it, ease discomfort, or prevent the disease from worsening.
 
Tumors may be benign, which means they are not cancer, or malignant, which means they are cancer. Some tumors grow slowly and stay in one place, while others can grow quickly or spread to other areas.
 
Often, surgery is the best way to treat a tumor. The aim is usually to take out the whole tumor and, when needed, some of the tissue around it. This helps lower the chance that the tumor will come back.
 
Some of the tumors and masses that are often removed with surgery include, skin and subcutaneous masses, mast cell tumors, soft tissue sarcomas, mammary tumors, oral masses, certain abdominal tumors, and other benign and malignant growths.

Tumor Removal What to Expect

What to Expect During Recovery

How your pet recovers after tumor removal surgery depends on the tumor’s size and location, how complex the surgery was, and your pet’s general health. We want to keep your pet comfortable and help them heal well.
 
Most pets go home soon after surgery and do well with the right care and monitoring.
Recovery often involves the following steps:
 
  • Pain management and supportive medications
  • Monitoring and care of the surgical incision
  • Restricted activity during the initial healing period
  • Follow-up examinations to assess recovery and healing
  • Review of biopsy or pathology results
  • Additional treatment recommendations when appropriate
 
If required, once we have the pathology results, we will review them with you, explain what they mean for your pet, and discuss any next steps. Depending on the results, this could mean more monitoring, additional treatment, or referral to a different veterinary specialist.
 
Our team will be here to guide and support you during your pet’s recovery, so your pet has the best chance to get better.

Not always. Some masses are benign and may simply require monitoring. Others may benefit from removal to obtain a diagnosis, prevent growth, or treat cancer. Evaluation by a veterinarian is the best way to determine the appropriate course of action.

In many cases, testing such as a fine needle aspirate, biopsy, or pathology examination is needed to determine whether a tumor is benign or malignant.

Some complex tumors benefit from advanced imaging before surgery. If a CT scan is recommended, we can help coordinate imaging with a trusted local facility.

For some tumors, complete surgical removal may be curative. Other cancers may require additional treatments such as chemotherapy, radiation therapy, or ongoing monitoring.

Boreal Animal Surgery focuses on surgical treatment. When chemotherapy or other oncology services are needed, we work closely with trusted veterinary oncologists to coordinate your pet’s care.

Recovery varies depending on the type of tumor and procedure performed. Many pets recover within a few weeks, although more extensive surgeries may require additional healing time.
