How does robotic cancer surgery work?

The surgeon sits at a console and controls instruments attached to a surgical robot. A camera provides a magnified view, while the instruments can move in confined spaces. The robot does not decide what to remove or operate independently. The surgeon makes those decisions and guides every movement. The operation is performed under anaesthesia, with instruments passed through small cuts. Depending on the cancer and its location, the surgeon may remove a tumour, nearby tissue or lymph nodes, then close the openings. Robotic surgery is one form of minimally invasive surgery; keyhole cancer surgery uses instruments through small openings without the same console-controlled system. The approach is not suitable for every tumour or patient.

Before surgery, share your medicines, allergies, previous operations and health conditions with the team. Follow instructions about fasting, bathing and medicines. Arrange transport and support at home if advised. Afterward, follow wound-care and activity instructions, take pain relief as prescribed, and attend follow-up visits. Ask when you can shower, drive, work and resume exercise. Recovery depends on the operation, the organ treated and your general health.

Contact the surgical team promptly for fever, worsening pain, redness or discharge from a wound, repeated vomiting, or difficulty passing urine. Seek urgent help for severe breathlessness, chest pain, fainting or heavy bleeding. After prostate surgery, inability to pass urine or rapidly worsening bleeding needs prompt assessment.

Ask why robotic surgery is being considered, what tissue will be removed, whether an open operation or keyhole approach is also possible, and what could make the surgeon change plans. Discuss anaesthesia, expected hospital stay, catheter or drain care, pathology results and warning signs.
