Does pet insurance cover cancer treatment?

Cancer diagnosis and treatment are covered by accident-and-illness plans, as long as the cancer isn't pre-existing.

Usually covered. Cancer diagnosis and treatment are covered by accident-and-illness plans, as long as the cancer isn't pre-existing.

Diagnostics (imaging, biopsies), surgery, chemotherapy, and radiation for a new cancer are among the most valuable things pet insurance pays for — courses can run $5,000–$15,000.

Coverage applies only if there were no signs of the cancer before your policy or waiting period, which is why enrolling early matters so much.

Your reimbursement is your percentage (70–90%) of the bill after the deductible, up to your annual limit — so choose a limit that could absorb a serious diagnosis.
