Nature of Service

Blue Book Search is a private, non-commercial interface for the World Health Organization (WHO) Classification of Tumours ("Blue Books"), which is published by the WHO's International Agency for Research on Cancer (IARC). This service provides two main features: (1) a search tool that helps users find specific tumor entities, and (2) a hierarchical browser that allows users to navigate the complete classification structure. Both features direct users to the corresponding chapters in the official WHO Classification of Tumours online platform.

Important: This service does not host, distribute, or provide access to the WHO/IARC content itself. Users need their own valid subscription to the WHO Classification of Tumours online platform to access the actual medical content.

This website is operated privately by a medical professional as a free educational tool. The service is provided on a strictly non-commercial basis without any fees or paid advertising. This service is operated independently and is not affiliated with or endorsed by the operator's employer.

Liability for Content

The content of this website has been created with the greatest care. However, no guarantee can be given for the accuracy, completeness, and timeliness of the content. As a service provider, Blue Book Search is responsible for its own content in accordance with § 7 Abs. 1 DDG and general laws. According to §§ 8 to 10 DDG, there is no obligation to monitor transmitted or stored third-party information.

This service displays only tumor entity names and basic classification hierarchy information; all other clinical content is exclusively accessible through the WHO platform. Liability is only possible from the time of knowledge of a specific legal violation. Upon becoming aware of such violations, the content will be removed immediately.

Liability for Links

This service contains external links to the WHO Classification of Tumours online platform and Google authentication services. There is no influence over the content of these external sites. Therefore, no guarantee can be assumed for these external contents. The respective provider (WHO/IARC and Google) is responsible for the content of the linked pages.

The linked pages were checked for possible legal violations at the time of linking. Illegal content was not recognizable at the time of linking. However, permanent content monitoring of the linked pages is not reasonable without concrete evidence of a legal violation. Upon becoming aware of legal violations, such links will be removed immediately.

This website is an independent project and is not affiliated with, endorsed by, or officially connected to WHO/IARC. Blue Book Search is a third-party search tool that helps users navigate to WHO's official content.

All medical content accessed through this service belongs to and is provided by WHO/IARC. WHO/IARC retains all rights to their WHO Classification of Tumours content. Users must comply with IARC's Terms of Use when accessing the official platform: https://publications.iarc.who.int/Terms-Of-Use

Important Medical Notice and Liability Limitations

No Medical Advice or Treatment: This is a search tool only — it does not provide medical content, advice, diagnosis, or treatment recommendations. While the operator is a medical professional, this website operates exclusively as a technical service, not as a medical service. This search tool does not replace professional medical advice, diagnosis, or treatment.

Professional Responsibility: Healthcare professionals using this service bear full responsibility for their diagnostic and therapeutic decisions. The operator expressly disclaims any liability for medical decisions, patient outcomes, misdiagnoses, treatment delays, or any adverse events that may result from information accessed through this service, whether used correctly or incorrectly.

Emergency Situations: This service is not intended for emergency medical situations. In case of medical emergencies, contact emergency services immediately. Do not rely on this search tool for time-sensitive medical decisions.

Information Accuracy: While this service aims to provide accurate search results, the operator makes no warranties about the completeness, accuracy, or timeliness of search results or the accessibility of WHO/IARC content. Users must verify all medical information through official sources and current medical literature.

Maximum Liability Limitation: To the fullest extent permitted by law, the operator's total liability for any claims arising from this service shall not exceed the amount of fees paid by the user (currently zero, as this is a free service). This limitation applies regardless of the legal theory of liability, whether in contract, tort, or otherwise.
