Optimal Cancer Diagnostic Pathways

CfSD’s Earlier Cancer Diagnosis Programme Board is responsible for commissioning optimal cancer diagnostic pathways to be developed in NHS Scotland.

Overseen by the Cancer Improvement and Earlier Diagnosis Team, this clinically-led process involves engagement with and input from specialist teams across NHS Scotland.

The development of optimal cancer diagnostic pathways will help improve the timeliness and efficiency of the diagnostic pathway, enabling accelerated access to treatment for those with a cancer diagnosis, while providing reassurance and reducing anxiety for those who do not.

A framework has been developed to agree, based on evidence, the order in which optimal pathways are developed for cancer types in Scotland. The lung cancer diagnostic pathway was published in December 2022, head and neck in January 2024 and colorectal August 2025.

Details on all optimal diagnostic pathways (including step-by-step weekly information and good practice examples) can be found on the Right Decision Service website.
