What is a 'loss of chance' claim?

Some states allow compensation when negligence reduced a patient's chance of survival or recovery, even if the chance was already below 50%. Other states do not recognize the theory. Whether it applies depends on your state's law.

Which cancers are most often missed?

Cancers frequently cited in diagnostic-error studies and malpractice claims include breast, colorectal, lung, prostate, and skin cancers (including melanoma), often because an abnormal screening result or persistent symptom was not followed up.

Can I bring a claim if the patient has died?

Yes. A family member or estate representative may bring a wrongful death or survival action, subject to the state's filing deadline, which often runs from the date of death.

How long do I have to file?

State statutes of limitations vary, generally one to three years from injury or discovery. Special rules apply to minors and to deaths. Contact a lawyer promptly.

How much does a case review cost?

Case reviews through Medical Malpractice Claim are free and confidential. Most malpractice attorneys work on contingency where permitted by state law.

Direct answer

A cancer misdiagnosis claim involves a missed, delayed, or incorrect cancer diagnosis that allowed the disease to progress to a later stage, required more aggressive treatment, reduced the chance of survival, or caused death. Claims depend on expert evidence showing that earlier, competent diagnosis would likely have changed the outcome.

Overview

Cancer misdiagnosis claims usually hinge on staging. Oncology experts reconstruct when the cancer should reasonably have been detected — from symptoms, screening results, or imaging — and what stage it would likely have been at that point. Some states also recognize a 'loss of chance' theory, where a reduced chance of survival is itself a compensable harm.

These cases require a careful records review and qualified medical expert testimony. Outcomes depend on the strength of the evidence, the jurisdiction's rules, and the patient's damages.
