By Dr. Tan Wah Siew & Dr. Lee Ser Yee
Surgical Oncology is the field of surgery which focuses on the surgical management of cancer. Surgery may be used to diagnose, stage and treat cancer. This is one of the three cornerstones of cancer treatment alongside systemic chemotherapy and radiation.

Most tumours require surgical expertise to obtain tissues for diagnosis and the first line treatment for nearly all solid tumours is surgical resection if it is amenable. For some tumours, cancer surgery may offer a chance of cure, especially if the cancer is localised or at an early stage. In other cases, it may be used as a primary treatment in conjunction with other therapies and/or for symptoms relief, for palliation and comfort.


The type of surgical procedure used to treat cancer differs depending on the type, size and stage of the cancer and its location within the body, taking in consideration patients’ factors as well. Surgery may be used to remove cancerous tumours, identify whether cancer has spread to nearby lymph nodes, reconstruct areas of the body or relieve symptoms for people with advanced cancer.

Our surgical oncologists specialize in treating one or more types of cancers, such as cancers in the colon, rectum, liver, pancreas, gallbladder, bile ducts and gastrointestinal tract. Our surgeons are specially trained in minimally invasive techniques like robotic surgery and laparoscopic surgery for cancer treatment.

Our Team

Our team adopts a comprehensive approach to surgical measures for cancer and our specialists are key members of multidisciplinary teams that treat cancers of the liver, gallbladder, pancreas, colon, rectum, gastrointestinal tract and more. The team champions multidisciplinary care through close collaboration amongst surgeons, oncologists, physicians, nurses and allied health professionals to ensure that our patients benefit from the best holistic care.

Dr. Tan and Dr Lee both trained in Singapore General Hospital and National Cancer Centre Singapore and furthered their training in high-volume and renowned cancer centres in the UK and US. Our clinic practices evidence-based medicine and sets standards and guidelines for cancer treatment.
