Abstract
Abstract A device and methods for inducing apoptosis in precancerous, cancerous and hyperproliferating cells by applying ultrasonic energy. The methods can include use of ultrasonic energy in combination with antioxidants and/or conventional therapies such as hormonal therapy, radiation therapy or chemotherapy. The device for the ultrasonic energy source can include a transmitter and a control unit.
