What does tumour ablation treat?

Doctors may consider ablation for some small, localised tumours in organs such as the kidney or liver. It may also be used when liver metastases are limited in number or location, or when surgery would be difficult because of a person's health or the position of a tumour. Radiofrequency and microwave methods use heat; other techniques use freezing or a different energy source.

Suitability depends on tumour size, number, exact position, nearby blood vessels or ducts, overall health and the wider treatment plan. Imaging helps the team guide the treatment and check the treated area. Ablation may be the main local treatment, part of combined care, or a way to control a tumour when removal is not appropriate.

Ask how the tumour will be reached, what type of energy is planned, and whether a sample of tissue is needed. Discuss medicines that affect bleeding, anaesthesia, pain control, expected monitoring and how follow-up scans will assess the result. Compare ablation with removal surgery and other options in the context of your tumour, not as a general ranking of treatments.

Follow the discharge instructions and contact the treatment team for worsening pain, persistent vomiting, bleeding, breathing difficulty, fainting, confusion or a new fever. Seek urgent help for severe abdominal pain, yellowing of the skin or eyes, or sudden weakness. The exact warning signs depend on the organ treated and the access route.

Why is ablation suitable for my tumour? Which technique will you use? What alternatives should I compare, including surgery? How will follow-up imaging guide the next step?
