The length of the longest diameter of the study lesion must be \< 5 cm and the calculated treatment volume (tumor volume plus a 0.5 cm margin around the tumor) for the study lesion \[where treatment volume = 0.5 (a+1) (b+1)2 and where a = length of the longest diameter (cm), b = the next longest diameter perpendicular to "a" (cm)\] must be \< 60.0 cm3. 3. Age: 18 years or older. 4. Male or female. 5. Men and women of childbearing potential must be using Investigator prescribed contraceptive methods while undergoing protocol related therapy. 6.

Up and about more than 50% of waking hours. 7. Life expectancy of at least 6 months. 8. Subjects must sign a written Informed Consent prior to receiving any study procedures or treatments. Exclusion Criteria: 1. Subjects with tumors suspected of involving a 50% or greater encasement of a blood vessel as measured by magnetic resonance imaging (MRI) or computed tomography (CT) scan. 2. Subjects with tumors having bone invasion. 3. Subjects with hypersensitivity to bleomycin. 4. Subjects who have received or will exceed a total lifetime dose of bleomycin greater than 400 units. 5. Subjects deemed unsuitable for general anesthesia. 6. Subjects with a significant history of emphysema or pulmonary fibrosis. 7. Subjects with indwelling cardiac pacemakers who cannot tolerate a period with pacemaker turned off. 8. Subjects with a history of uncontrolled cardiac arrhythmia. 9.
