The surgical oncologists at the Center for Advanced Surgical Oncology are specially trained in common and complex cancer surgery utilizing some of the latest technology. These techniques include robotic-assisted procedures, laparoscopic, open or hybrid approaches, alone, or in combination with, intraoperative radiation therapy, microwave ablation and intraoperative ultrasound. The broad range of procedures includes minimally invasive intra-abdominal gastrointestinal surgery, endocrine tumors, retroperitoneal and extremity soft tissue neoplasms, as well as the entire range of skin tumors. Our experts use some of the latest surgical advances and minimally invasive surgical techniques to diagnose, stage and treat benign and malignant tumors. Our surgeons are trained and have significant experience with surgical procedures that include:

  • Biopsies – minimally invasive procedures to obtain tissue samples to determine if cancer is present
  • Tumor staging – to determine if the cancer is in an early or advanced stage and to tailor optimal treatment
  • Tumor removal – surgically removing the tumor, the extent of the resection is determined by the nature of the neoplasm and the organ or organs affected
  • Reconstruction – surgically repairing or replacing the area affected by the removal of the cancerous tissue

Our dedicated team of surgical oncologists has the expertise and extensive experience needed to treat complex cancers involving the stomach, liver, pancreas and esophagus, as well as in colorectal malignancies. In addition, our experts focus on the management of thyroid tumor, breast benign and malignant neoplasms, retroperitoneal and extremity sarcomas, as well as the entire range of common and complex skin tumors.

Our surgeons are members of the Center for Advanced Surgical Oncology with an office at Palmetto General Hospital in Hialeah where they perform selected procedures.

When to See a Surgeon for Oncological Surgery?

Your primary care physician or your medical oncologist, a physician who specializes in treating cancer with drugs and oversees all aspects of your cancer care, may refer you to a surgical oncologist, or surgeon that specializes in cancer related surgery. Treatment plans may include radiation and/or chemotherapy, in addition to surgery.

Because surgical oncology is typically complex, many oncological surgeons specialize in management of one or two types of cancer. You may also see a radiation oncologist if your care

includes radiation treatment. Regardless of your case, the surgical oncologists at the Center for Advanced Surgical Oncology help provide options for your cancer care so that you may achieve the best outcome.
