Pet insurance for cancer
Cancer that is first diagnosed after enrollment and the waiting period is generally covered, including diagnosis, surgery, and chemotherapy, subject to the annual limit. A lump or other sign recorded before the policy starts can make that cancer pre-existing, and high annual limits matter because a single course of treatment can use up a small limit.
What it is
Cancer is uncontrolled growth of abnormal cells, which can form a lump in one place or spread through the body, and it becomes more common as dogs and cats age. Owners often visit a vet because of a new lump, weight loss, loss of appetite, or a wound that will not heal.
What treatment typically costs
Cancer diagnosis, surgery and treatment typically runs $5,000 to $25,000 and up

What a claim would pay
A worked example
- The bill for treating cancer comes to $15,000.
- The yearly deductible takes off $500, leaving $14,500.
- The policy reimburses 80 percent of $14,500, which is $11,600.00.
The policy pays $11,600.00 and you pay $3,400.00.
Example terms only: a $500 yearly deductible and 80 percent reimbursement, with the deductible not yet met this year. Your own policy terms decide a real claim.
