Online learning has become a valuable teaching method given the Covid-19 Pandemic. It provides more agile and flexible access to information, allowing the connection of teachers and students independently of their geographical location. Yet, there are different challenges tied to this new reality that professors and students need to overcome. This paper aims to report the perspective of medical students on oncology Webinars that occurred before the Covid-19 pandemic. Four meetings were held via virtual platforms, in which students from a medical school in Paraná, Brazil, connected with master students from a university in Minas Gerais, Brazil, partner with a research laboratory and an American university. Thereupon, the Webinar added valuable contributions to the medical science undergraduates, improving their oncology knowledge and networking skills. However, it is necessary to understand and overcome barriers in medical teaching so that this new way of learning becomes more common and accessible.
