Cancer (active treatment): Documentation That Wins a Disability Claim

Active chemotherapy or radiation is the cleanest claim in disability insurance — the treatment schedule itself proves inability to work. The question is what happens at remission, when the own-occupation definition gets tested.

What the insurer looks for

Objective beats subjective in every claim. Build the file in months, not weeks: consistent specialist visits, diagnostic testing, and a documented medication history.

Building the claim file

• Get the job description into the treating physician’s hands — function is judged against work, not against wellness.
• Keep a symptom journal with bad-day specifics; generic ‘pain daily’ entries carry no weight.
• File early. Waiting months while ‘trying to push through’ reads as ability to work.

The denial pattern to expect

Expect the carrier to argue inconsistency — surveillance on a good day vs the claim file. Approved during active treatment claims survive it when the medical record shows the pattern, not just the diagnosis.

Cancer (active treatment) claims are documentation contests: the diagnosis starts the file, the functional evidence wins it.
