[Organizational principles of the outpatient examination of patients suspected of malignant tumors].

Out-patient diagnosis of cancer is carried out in three stages which involve activities of different physicians. Cancer is first suspected by a general practitioner. Prophylactic measures other than examination by specialists and chest photo-roentgenography proved insufficient, and the authors give reasons for this. During the second stage, the patient undergoes further thorough examination which should be well organized to succeed. The third stage, viz. making the final diagnosis, should be performed in an oncologic establishment only.
