[Logical structure graphs in the teaching of oncology]

The graduates of medical institutes are the first link in the general therapy network, where all patients with pretumor and tumor lesions are referred to for medical aid. It is the rate of their training in oncology that the number of patients with advanced malignancies depends on. To improve the teaching of oncology the writers have used the graphs of logical system, which enabled not only the student but also the teacher to concentrate their attention on the key, basic problems, to choose the necessary information and to reject an excessive secondary one. The graphs of logic system allow the student to realize and understand the structure of the subject concerned, as a whole, the relationship of separate elements under study, thus being a visual aid contributing to better mastering the subject. The former offer good grounds for a scientific approach to the teaching problems.
