Oncologic Surgery in Milwaukee, Mequon, Glendale, Cudahy, Germantown, Saukville and Waukesha

A cancer diagnosis changes everything, and the surgeon you choose matters. Madison Medical's oncologic surgery team removes cancerous tumors and affected tissue with precision, while working alongside your oncologist to support your full course of treatment. We serve patients across Milwaukee, Mequon, Glendale, Cudahy, Germantown, Saukville, and Waukesha, so you don't have to travel far for expert surgical cancer care.

What Oncologic Surgery Treats

Oncologic surgery focuses on removing cancerous tumors and, when needed, the surrounding tissue or lymph nodes to stop the cancer from spreading. This can be the primary treatment for your cancer, or it can work alongside chemotherapy, radiation, or other therapies as part of a broader treatment plan. Your surgeon's goal is always the same: remove the cancer completely while preserving as much healthy tissue and function as possible.

Common Oncologic Surgery Procedures

  • Breast cancer surgery, including lumpectomy and mastectomy
  • Sentinel lymph node biopsy and axillary lymph node dissection
  • Removal of cancerous skin lesions and soft tissue tumors
  • Abdominal tumor removal
  • Thyroid and endocrine gland surgery for cancerous nodules
  • Colon and rectal cancer surgery

Each procedure is planned around your specific diagnosis, tumor location, and stage of disease.

Meet Our Oncologic Surgery Team

Our entire team of surgeons - Dr. Richard Cattey, Dr. Jasna Coralic, Dr. Alysandra Lal, Dr. Joseph Regan, and Dr. Craig Siverhus - specialize in oncologic surgery. They partner closely with medical oncologists, radiation oncologists, and your primary care physician to make sure your surgical treatment fits into a coordinated plan, rather than functioning as an isolated step.

What You Can Expect

Your first appointment focuses on understanding your diagnosis completely. Your surgeon reviews your imaging, pathology reports, and any prior treatment, then explains how surgery fits into your overall care plan. You'll have time to ask questions about the procedure itself, recovery, and what comes next, including additional treatment if it's needed. Once a plan is set, you'll receive clear pre-operative instructions, and after surgery, your team schedules close follow-up to monitor your healing and review pathology results from the removed tissue.

A cancer diagnosis is overwhelming enough without disconnected care. Our oncologic surgeons work as part of your full treatment team, sharing information directly with your oncologist instead of leaving you to relay details between offices. We use minimally invasive techniques whenever your case allows it, which can mean a shorter hospital stay and faster recovery, so you can move into the next phase of treatment sooner. Most importantly, you get a surgeon who explains your diagnosis and your options in language you can actually use to make decisions.

Pathology results from your surgery often shape the rest of your treatment plan, including whether you need additional therapy. Your surgeon reviews these results with you directly and coordinates with your oncology team to determine the right next steps, so you're never left waiting for answers without a clear point of contact.
