Find Cancer Early for General Practitioners

In Australia, over 75 per cent of cancers first present in general practice as a result of symptoms.1 General Practitioners (GPs) play a key role in the early detection of cancer, however they can often experience challenges in early diagnosis of cancers;

  • GPs will only see five to 10 new cases of cancers (excluding skin cancers) among several thousand consultations per year.
  • Most symptoms of cancer have more common benign causes.
  • Cancers in general practice often present initially with more subtle non-specific symptoms.1

Find Cancer Early aims to promote earlier detection and diagnosis of four of the most common cancers in Western Australia (WA); colorectal, lung, prostate and breast.


Find Cancer Early: A Guide for General Practitioners

‘Find Cancer Early: A Guide for General Practitioners' is a tool designed to assist WA GPs in the early diagnosis of patients with colorectal, lung, prostate and breast cancer. The resource utilises an evidence-based approach to recognise cancer symptoms earlier.

Developed in consultation with the Cancer Council WA General Practice Advisory Committee and Professor Jon Emery (Herman Professor of Primary Care Cancer Research, University of Melbourne); the guide incorporates risk assessment tools (positive predictive value tables) developed from the CAPER studies by Professor William Hamilton and colleagues at Cancer Research UK.

Find Cancer Early Guide

The guide is formatted as follows:

  • Symptoms that best predict cancer
  • Positive Predictive Value (PPV) tables for each of the four
    cancer types: 
    • PPVs quantify the probability of cancer for
      individual and pairs of clinical features
      (in patients over the age of 40). 
    • The risk values represent the proportion of people out
      of 100 with individual or combinations of clinical features, who will have an underlying cancer. 
    • The colour codes and associated risk values can help support decisions about investigation and referral, and are designed to be used alongside clinical judgement and professional experience. 
      • Probabilities highlighted in red are greater than 5%; urgent referral should be considered.
      • Probabilities highlighted in orange are between 2 - 5% and probably warrant prompt investigation.
      • Probabilities highlighted in yellow are between 1 - 2% and require follow-up and possible investigation to rule out any underlying serious condition.
      • Probabilities highlighted in white are less than 1%.
  • Risk factors
  • Implications for practice
  • Diagnostic pathways
  • Referral criteria
