Introduction. Oncology is one of the areas of medicine where the introduction of artificial intelligence (AI) technologies is expected to be most effective. However, the specific nature of decision-making in oncology, where a mistake can cost a patient's life, makes the issue of professional trust in AI particularly acute. To date, no studies have been conducted on the attitude of Russian oncologists to AI. The purpose: to investigate and characterize the attitudes of Russian oncologists towards AI technologies, including their level of awareness, frequency and nature of use, degree of trust in algorithmic decisions, and subjective perception of the accuracy of AI systems. Materials and methods. An anonymous online survey was conducted on the platform Anketolog.ru (March–July 2026). 249 specialists who indicated the specialty "Oncology" were selected from the general database of responses. A questionnaire of 26 closed-ended questions (two blocks). Statistical analysis: Mann–Whitney, Kraskel–Wallis criteria, Spearman coefficient (p); cluster analysis by threshold aggregation. Results. Selection: 249 oncologists, 64.7% women, average age 37.2 ± 11.0 years. 43.8% do not use AI in their professional activities. 68.7% rate their trust in AI as insignificant or absent. The subjective assessment of AI accuracy is 49.8%, the accuracy of doctors is 72.9%, and the effectiveness of prescribed treatment is 77.1%. Oncologists with AI experience demonstrate significantly higher trust (2.33 vs. 1.86; p
