It is recognised that survivors and their healthcare professionals have the final responsibility for making decisions concerning their long-term follow-up care. As such, they may choose to either adopt these recommendations or not to do so after individual informed discussion. It is good practice to document this decision.

In addition to regular surveillance, real-time awareness and prompt reporting of new symptoms and signs is essential to the early detection and timely treatment of late effects.
