CHEST FLUOROSCOPY AND NEOPLASIA IN TUBERCULOSIS PATIENTS: A RETROSPECTIVE SURVEY September 1, 1971 — January 31, 1973

摘要

Patients subjected to frequent diagnostic x-ray irradiation exposure as a result of pneumothorax or pneumoperitoneum therapy for cavitary pul¬monary tuberculosis are being surveyed for incidence of neoplasia.
