Cancer & Toxic-Exposure Claims

Step 1 - Document the cancer diagnosis

VAC generally needs medical evidence establishing a diagnosed condition. Gather relevant documents you have and identify where additional records may be obtained.

• Pathology or diagnostic report confirming the type and site of cancer.
• Specialist consultation reports, imaging, surgery and treatment summaries, where relevant.
• Approximate dates of first symptoms, investigations, diagnosis, recurrence or progression.
• Relevant medical history and other information your treating clinician considers pertinent.
• A list of records not yet obtained and who may hold them.

Do not delay seeking guidance simply because you are still collecting records. Follow current VAC application instructions and ask a representative how best to handle missing documents.

Step 2 - Reconstruct the service and exposure timeline

Write down what you personally remember about the work, location or event. VAC's hazardous-material policy identifies the mode and extent of exposure and the time between exposure and onset of the condition (latency) as relevant considerations. The decision is made on the individual merits and evidence of each case.

• Where: ship, base, workshop, deployment, building, training area or other location.
• When: service period and approximate dates; label uncertain dates clearly.
• What: substance, material, process, equipment, smoke, dust or other suspected hazard, if known.
• How: inhalation, skin contact, ingestion or another route, only if known or reasonably described.
• How often/how long: frequency, duration, work pattern and whether protective measures were used, if remembered.
• What supports it: service records, trade or duty descriptions, safety documents, incident reports, photographs, orders or witness statements.
• What remains uncertain: unknown chemical name, concentration, dates or duration. State the uncertainty rather than guessing.

Step 3 - Build an evidence map

A short evidence map helps you see what each document contributes and where there may be gaps.

Step 4 - Prepare your personal statement

Use a chronological account in plain language. Explain your duties and what you observed, the timeline of the condition, and where supporting documents can be found. Separate your direct memories from information you learned later. Do not state that an exposure caused your cancer as a medical fact unless that conclusion is supported by appropriate evidence.

Step 5 - Submit, track and keep copies

• Use current official VAC forms and submission instructions.
• Keep a complete copy of the application and all attachments.
• Record the submission date and confirmation details.
• Track requests for further information and your response dates.
• Save every decision letter and note when it was received.
