C the Signs

C the Signs is an AI-driven platform, created by NHS doctors, that leverages cutting-edge data analytics to detect cancer early: when it is most treatable.

Implemented in primary care, C the Signs analyses patient-reported data and electronic health records to identify patients at risk of cancer, determine the type of cancer, and guide healthcare professionals to the appropriate diagnostic or referral pathway.

C the Signs has already detected cancer in over 25,000 patients, spanning more than 50 cancer types, including rare and hard-to-detect cancers. With 99% sensitivity, 99% negative predictive value, and 94% accuracy in predicting tumour origin, it is transforming how cancer is diagnosed and treated.

This year, we’ve expanded the scope of our impact with the launch of C my Signs in the NHS. C my Signs empowers patients to use self-assessments for direct referrals, in collaboration with hospitals and diagnostic hubs, increasing the patient touchpoints that can lead to earlier detection.

C the Signs is a UKCA-marked Class I medical device, fully integrated with electronic health records and compliant with the highest security standards. It has been implemented across 1,400 GP practices in England, in partnership with Integrated Care Boards and Cancer Alliances.
