¹The 2019 survey included an initial question: “Was the patient’s cancer known to be detected by NHS cancer screening services relevant to this diagnosis?” any patient where the GP had responded yes to this question were excluded from further analysis and accounts for the difference in valid N between the analysis on referrals compared with PCI/DI.
