Does Pet Insurance Cover Cancer?

Cancer treatment is among the costliest pet health expenses. The good news: it's covered by most plans — if it isn't pre-existing.

What's covered

Accident-and-illness plans cover diagnostics, surgery, chemotherapy, and radiation for cancer that develops after your policy starts.

The pre-existing rule

If your pet showed any signs of the cancer before coverage began, it's excluded — making early enrollment critical, ideally while your pet is young.
