Course objectives
The course aims to uncover key mechanisms leading to tumor formation and development and to link them to basic mechanisms regulating cell functions and intercellular relationships.
Learning outcomes
At the end of the course students should be able to understand cancerogenesis as multistep process and to comprehend main molecular mechanisms responsible for tumor progression.
