Causation — the link between the exposure and your illness — is the heart of a toxic-tort case, and it is understandably the part people worry about most. The good news is that proving the science is the work of the case and its experts, not something that falls on you.
Establishing causation generally means building two connections. The first is exposure: showing that you were meaningfully exposed to the substance, drawn from your work or residential history, environmental or workplace testing, and records. The second is the medical link: showing that the substance is capable of causing your diagnosis and did contribute to it, supported by your medical records and the analysis of medical and scientific experts.
Preserving evidence early strengthens both connections, because sites change, records are lost, and memories fade. That is why, even though deadlines in these cases can relate to discovery of the harm, starting the investigation sooner rather than later helps. We gather the exposure and medical evidence and work with the right experts to build the connection your claim needs.
