Methods of treating a subject suffering from a disease or a disorder associated with hyperproliferating cells. The method includes non-invasively administering to the subject ultrasound at a low intensity in a dose effective to selectively prevent the growth of the hyperproliferating cells or to eliminate the hyperproliferating cells in the subject, while substantially not affecting the cell viability of normal cells of the subject. The low intensity is pre-determined to be lower than a cavitational threshold intensity for a selected frequency.
