Does pet insurance cover cancer?
Yes: every US policy we've read that mentions cancer treats it as an illness it can cover, and some name chemotherapy and radiation in black and white. What really matters is timing. If a lump, a bump or an abnormal test result shows up before your policy starts, or during the waiting period, that cancer is treated as pre-existing. A few insurers also have their own rules about a cancer your dog has had before. Here's what each policy says.
When isn't cancer covered?
When it counts as pre-existing: any sign of it, such as a lump your vet noted, before your policy started or during the waiting period for illness (usually 14 days). That's why it pays to insure your dog while they're young and healthy.

Cancer treatment named as covered, including chemotherapy and radiation
Covered as an illness, with rules about cancer that showed before
- LemonadeIts FAQ says the base accident and illness policy covers cancer diagnostics, treatments and medications, unless a lump, bump or abnormal test showed before you joined or in the waiting period.
- FigoCovered as an illness. A type of cancer diagnosed before your start date, or before the waiting period ended, is never covered, even if it comes back later.
- Pets BestCovered as an illness. A type of cancer your dog has had before isn't covered again, unless a lab report shows it was fully removed early, with clean margins; then the same type elsewhere may be covered.
- EmbraceCovers illnesses, and doesn't exclude cancer. A mass that showed before the illness waiting period ended isn't covered, including one caused by cancer.
Your questions answered
Can I get pet insurance for a dog that already has cancer?
You can still insure your dog, but the cancer they already have won't be covered, because it's pre-existing. Other new illnesses and accidents can be. Pets Best has one exception worth knowing about: if a vet's lab report shows a cancer was fully removed with clean margins before it could spread, the same type of cancer appearing somewhere else may be covered later.
Does pet insurance cover chemotherapy for dogs?
Pumpkin and Spot name chemotherapy and radiation in their policies, and Lemonade says its base policy covers cancer diagnostics, treatments and medications. With every insurer, the cancer must be new: it can't have shown signs before the policy started or in the waiting period.
What if a lump appears during the waiting period?
It will be treated as pre-existing, even if it turns out to be cancer later. Embrace says this in so many words, and lets a vet's cytology test show that later, unrelated problems can still be covered.
