Cancer Expert Witnesses
Cancer science sits at the center of some of the most consequential commercial litigation in the life sciences, chemical, and insurance sectors. Manufacturers defend claims that a product or workplace exposure caused malignancy, biopharmaceutical companies dispute the development, licensing, and performance of oncology therapies and diagnostics, and payors contest coverage for costly treatment regimens. These cases turn on scientific questions that remain genuinely contested: whether an agent is capable of causing a specific cancer, whether dose and latency fit the disease, and whether a treatment or diagnostic performed as represented. Because judges and juries must weigh competing interpretations of epidemiology, toxicology, and tumor biology, the quality of expert testimony frequently defines the case.
Rigorous cancer analysis separates general causation, whether an agent can cause the disease at all, from specific causation, whether it did so in the circumstances at issue. An expert evaluates the epidemiological literature, toxicological mechanism, exposure history, and latency period, and weighs alternative explanations such as genetic predisposition, smoking, or unrelated occupational exposures. In disputes over oncology products, the focus shifts to clinical trial design, biomarker validity, regulatory submissions, or whether efficacy data supported the commercial representations made about a therapy. Each of these inquiries bears on admissibility under Rule 702, on the strength of the liability case, and on how damages or contract remedies should be measured.
Cancer litigation rewards precision in expert selection, because an oncologist who treats the disease, an epidemiologist who studies its causes, and a toxicologist who explains its mechanisms each answer a different question. Round Table Group works with oncologists, neuro-oncologists, and surgical specialists who have testified on cancer causation and standards of cancer care, alongside toxicologists with decades of experience in carcinogenesis and occupational epidemiologists who have published on asbestos, formaldehyde, and ethylene oxide. The network also includes researchers in cancer genetics, medicinal chemistry, drug design, and tumor-marker diagnostics whose work speaks directly to product development and licensing disputes.
