José Manuel Bernabé, the former manager of the National Center for Oncological Research (CNIO) in Spain, has publicly revealed the extent of a corruption scandal that affected the center for at least 15 years. He claims that a mafia-like network within the institution may have embezzled as much as 30 million euros through manipulated contracts. Bernabé, who left his position amid allegations of harassment, has provided critical information to the authorities, including five reports to the Anti-Corruption Prosecutor's Office and the National Police's Economic and Fiscal Crime Unit (UDEF). The scandal highlights significant misuse of public funds and betrayals of trust in one of Spain's leading cancer research institutions.
