Cancer patients may be asked or may be interested in participating in a clinical trial.

A clinical trial represents a form of research carried out by healthcare professionals and scientists with the purpose of evaluating if a new diagnosis or treatment method is safe for patients and can improve their condition.

Treatments that are currently available were once part of clinical trials. The EORTC brochure on clinical trials offers patients the opportunity to learn basic concepts that relate to clinical trials and can complement the information provided by healthcare professionals.
