INNEG invites you to this free lunchtime webinar examining how skin cancer claims unravel in practice, and how medical evidence is used to assess breach, causation, and counterfactual outcomes where timelines and disease progression are disputed.
This session will explore common failures in the recognition and interpretation of skin lesions, delays in referral or treatment, and how these factors interact with the natural history of different skin cancers. Particular attention will be given to situations where evidence is incomplete or inconsistent, and where prognostic uncertainty becomes central to liability and quantum arguments.

Skin cancer clinical negligence claims frequently involve complex and highly contested issues around diagnostic delay, missed referral opportunities, and disease progression. Variability in presentation, inconsistent clinical documentation, and uncertainty around tumour behaviour often make causation and prognosis particularly difficult to assess.
Drawing on extensive medico-legal and clinical oncology experience, the webinar will also address how environmental and occupational factors may be considered within clinical assessment, and how counterfactual outcomes are evaluated when earlier diagnosis or treatment is alleged.
This session will help you to:
- Understand how diagnostic delay and misinterpretation of skin lesions arise in clinical practice
- Appreciate the variability in presentation and progression across different skin cancers
- Identify how missed referral or treatment windows are assessed in negligence claims
- Strengthen causation arguments where evidence is inconsistent or contested
- Navigate prognostic uncertainty and counterfactual outcomes when assessing liability and damages
