Oncology expert witnesses
Listed oncology expert witnesses address diagnosis, staging, treatment selection and the consequences of delay. Delayed diagnosis claims usually require an opinion on what stage the disease had reached at the earlier date.
01
The evidence
What an oncology expert witness is asked to determine
The central question in most oncology claims is what difference timing made. That requires the expert to address stage at the notional earlier date, the treatment that would then have been available, and the effect on survival or morbidity, each within the limits of the evidence.
- Whether the presenting symptoms warranted urgent referral under the pathway in force.
- What stage the disease had probably reached at the date the diagnosis should have been made.
- Whether the treatment given, including regimen and dose, met the expected standard.
- Whether toxicity and complications were recognised and managed appropriately.
- What can properly be said about the effect of delay on treatment options and outcome.
Practitioners are listed across the United Kingdom and Republic of Ireland. Location can be narrowed in the register’s location listings before an instruction is made.

Reports prepared
Imaging, staging and treatment records support a records review report. A breach and causation report addresses stage at the earlier date and the effect of delay.
Where life expectancy is in issue, a condition and prognosis report deals with it separately. The scope of each of those reports is described on its page.
Oncology expert witness evidence
An oncologist expert witness addresses stage at the earlier date and the treatment then available, and states the limits of any survival conclusion.
The register lists practitioners by discipline; availability is agreed with the practitioner. See guidance from Royal College of Radiologists alongside the case material.

Questions answered
Frequently asked questions
Will an Oncology expert witness respond to Part 35 questions?
Yes - CPR 35.6 entitles the parties to put written questions on a report, and answering them is part of the expert's duty to the court. A Oncology report prepared for proceedings in England and Wales carries the Part 35 statement of truth, with equivalent duties applying in the other UK jurisdictions.
Can an Oncology expert act as a single joint expert?
Where the court directs a single joint expert under CPR 35.7, the instruction is agreed between the parties and put jointly - a routine basis of instruction in this field. Whether a particular practitioner accepts SJE appointments is confirmed with the practitioner at the enquiry stage.
Will the expert attend joint discussions or give evidence at trial?
Where the court directs discussions between experts under CPR 35.12, they meet and produce a joint statement of what is agreed and what is disputed; attendance at trial - in person or by video link - is likewise a matter of court direction. These commitments are confirmed with the practitioner at instruction.
Can I choose an Oncology expert of a specific gender, or one who assesses remotely?
Yes on both counts. Every listing displays the practitioner's gender, consulting locations and assessment types - face to face, remote or both - so sensitive-instruction preferences can be applied at the shortlisting stage, before any contact is made.
