An ultrasound probe comprises one or more transducers positionable on, in proximity to or within a cancerous mass of tissue. The one or more transducers are capable of delivering sufficient levels of acoustic energy to (a) induce coagulative necrosis of a region of the tissue surrounding the transducer, and (b) induce sonoporation of a chemotherapy agent into cancer cells in the tumor and in the margins of tissue adjacent the necrosis region of tissue.
