An apparatus for detaching a solid tumour from surrounding tissue. It has an elongate radio frequency (RF) probe having a distal portion with an elongate electrode and at least one tissue detaching electrode connected to the elongate electrode. The tissue detaching electrode is extensible from a retracted position to a position at a predetermined distance from the longitudinal electrode to define an enclosed boundary of an area within which a solid tumour may be located. An RF current source provides an RF ablating current with a current return path between the elongate electrode and the tissue detaching electrode such that the RF ablating current extends through the region between the tissue detaching electrode and the elongate electrode to cause tissue death in that region and wherein the RF current source provides an RF cutting current for separating the tissue from surrounding tissue.
