Treatments & Services
Cancer Surgery
The goal of cancer surgery is to remove the cancerous tissue and a ring of normal tissue around it. The surgery may also include removing lymph nodes from the neck. Reconstructive plastic surgery may be needed if the cancer is widespread and requires extensive tissue removal. These may include surgery to the tongue, jawbone, facial skin, pharynx, or larynx. In cases such as this, tissue from other parts of the body, like the forearm or leg, can be transplanted to give patients the best possible cosmetic and functional outcomes.
Pancreatic Cancer Surgeries
Surgery is currently the most effective treatment for pancreatic cancer. The two types of surgery used to treat pancreatic cancer are potentially curative surgery and palliative surgery. Potentially curative surgery is performed if it appears the cancer can be removed entirely. If the cancer has spread too far to be completely removed, patients may be treated with palliative surgery. Rather than try to cure the cancer, the goals of palliative surgery are to relieve symptoms and prevent problems caused by the cancer, such as the cancer blocking the bile ducts or the intestine.
Liver Directed Therapy
Liver directed therapy is typically used when surgery is not an option for treatment. Liver directed therapy targets cancer in the liver and is often used to treat neuroendocrine tumors that have spread to the liver.
