Practical tools for pet owners
Questions for Your Oncology Appointment
Oncology consultations move quickly, and it is easy to leave without asking everything you meant to. Working through these questions before your appointment — and ticking them off as you go — means you will come away with a much clearer picture of your pet's situation and options.
Expand each section, tick the questions most relevant to your situation, and use the print button to take a copy with you.
Can you confirm the exact cancer type and subtype?
e.g. B-cell vs T-cell lymphoma, mast cell tumour grade I/II/III, or osteosarcoma vs chondrosarcoma. Subtype can significantly affect prognosis and protocol choice.
What stage is my pet's disease, and what does that mean practically?
Ask for the staging system being used (e.g. WHO staging for lymphoma) and what each stage implies for spread and treatment urgency.
Does this cancer have a substage — for example, substage a vs b — and how does that affect the prognosis?
In lymphoma, substage b (with systemic signs like weight loss or lethargy) typically carries a worse prognosis than substage a.
Is immunophenotyping recommended, and if so, has it been done or can it be arranged?
Immunophenotyping (flow cytometry or IHC) identifies whether lymphoma is B-cell or T-cell origin — a key prognostic factor.
Are there breed-specific genetic factors we should know about before choosing a treatment?
For example, the MDR1/ABCB1 mutation in herding breeds (Collies, Shelties, Australian Shepherds) affects how certain chemotherapy drugs are metabolised. Testing is available.
What additional tests are needed to complete staging, and what is the purpose of each one?
Common tests include chest X-rays, abdominal ultrasound, bone marrow aspirate, and flow cytometry. Understanding the "why" helps you weigh cost against benefit.
How long will the workup take before we can start treatment?
Some cancers are sensitive to delays. Ask whether there is any benefit to starting a bridging treatment (e.g. prednisolone) while staging is completed.
What is the expected prognosis with and without treatment?
Ask for median survival times and, ideally, 1-year survival rates for both treated and untreated cases so you can compare the benefit clearly.
What treatment protocols are available, which do you recommend, and why?
Ask the oncologist to walk through the first-line option and any alternatives. Understanding the reasoning helps you weigh intensity against likelihood of benefit.
What are the most common side effects, and how are they managed if they occur?
Most veterinary chemotherapy is tolerated better than human chemotherapy, but GI effects, bone marrow suppression, and fatigue are possible. Ask what to watch for at home.
What does "response to treatment" mean for this cancer, and how will you measure it?
Response can mean complete remission, partial remission, or stable disease. Ask how response is assessed (imaging, repeat biopsy, lymph node palpation) and what each outcome implies.
How often will we need to come in for treatments and monitoring appointments?
CHOP-based protocols typically require weekly visits in the first phase. Understanding the schedule helps with logistics and realistic planning.
What does monitoring during treatment involve — and at what cost?
Regular CBC (complete blood count) checks are standard. Ask what other tests will be done, and whether some monitoring can be performed by your primary vet.
What is the likely quality of life for my pet during treatment?
Explicitly ask whether pets typically feel well enough to exercise, play, and eat normally. This is often better than people expect.
If my pet doesn't respond to the first protocol, are there rescue options?
Rescue protocols (e.g. MOPP, LOPP, or single-agent lomustine) exist for some cancers. Knowing this upfront can reduce anxiety about first-line failure.
Is surgery, radiation, or immunotherapy a possibility alongside or instead of chemotherapy?
Multimodal approaches are standard for some cancers (e.g. sarcomas, nasal tumours). Ask whether a referral to a radiation oncologist or surgeon would be beneficial.
What is the estimated total cost for a full course of the recommended treatment?
Ask for a realistic range rather than a minimum. Include staging, all treatment visits, monitoring bloodwork, and any medications sent home.
Can you provide a cost breakdown by phase — staging, treatment visits, and monitoring?
This helps identify where the major costs sit, and whether any parts (e.g. some bloodwork) could be done at a lower-cost primary care clinic.
What happens if we need to pause or stop treatment partway through?
Ask whether a partial course still provides meaningful benefit, and whether there are extra risks from stopping mid-protocol (e.g. drug resistance).
Are there less expensive protocol options, and how do their outcomes compare?
Single-agent or oral-only protocols often cost significantly less than multi-agent protocols. Ask the oncologist to be direct about the trade-off in efficacy.
Is pet insurance likely to cover any of this treatment, and can your team assist with claim paperwork?
Coverage depends heavily on when the policy was taken out relative to diagnosis. Many oncology practices have staff experienced in supporting insurance claims.
Is a payment plan available, or are there financial assistance resources?
Some specialist centres offer payment plans or can refer to veterinary charitable funds. It is always worth asking directly.
What is the minimum treatment that could still provide meaningful benefit?
For owners with tight budgets, understanding the minimum viable intervention — such as a single induction cycle — can help frame a realistic plan.
Is my pet potentially eligible for any clinical trials?
Trials have specific eligibility criteria (species, breed, cancer type, prior treatment, age, weight). Ask explicitly whether this diagnosis is being studied.
Where would the trial be conducted, and how often would we need to visit?
Some trials require visits to a university veterinary school. Understanding the location and frequency helps assess whether participation is feasible for you.
What does participation involve — what tests, treatments, and time commitment?
Ask for a full protocol overview: what is the investigational treatment, what additional procedures are required beyond standard care, and over what timeframe.
What are the costs, and which elements — if any — are covered by the trial?
Many trials cover the investigational drug and some associated monitoring. Standard-of-care elements are often still the owner's responsibility. Get this in writing.
What are the potential risks and benefits compared to the standard treatment?
Ask the oncologist to give an honest comparison. A trial does not automatically mean better outcomes — understand the uncertainty involved.
How can I find out about other ongoing trials if my pet isn't eligible for one here?
The Veterinary Cancer Society and university veterinary schools often maintain trial registries. Ask if there are other centres running relevant studies.
If we choose not to pursue aggressive treatment, what palliative care options are available?
Palliative care focuses on comfort and quality of life rather than cure. Ask what a palliative plan would look like in practical terms for this specific cancer.
What medications are typically used for pain and symptom management, and what signs should prompt a call to you?
Common options include NSAIDs, opioids, gabapentin, and steroids. Ask for a clear list of warning signs that would warrant urgent contact.
What does a typical week look like for a pet on palliative care — how will we manage their comfort day-to-day?
Understanding the practical routine — medications, activity restrictions, diet, monitoring — helps set realistic expectations and reduces anxiety.
How will we know when my pet's quality of life is declining, and what should I do when that happens?
Ask the team to describe specific observable signs in plain language — changes in appetite, mobility, interaction, or breathing — so you know what to look for.
Can you walk me through the HHHHHMM quality-of-life scale and how to use it for my pet?
The HHHHHMM scale (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad) is a validated tool for monitoring quality of life at home. Ask your vet to go through it with you.
How do we access hospice or end-of-life support when the time comes?
Ask whether in-home euthanasia is available, what the process looks like, and whether there are grief or bereavement resources the practice can point you toward.
Are there palliative chemotherapy options that might slow progression without aiming for remission?
Lower-dose or metronomic chemotherapy protocols can sometimes extend comfortable life without intensive side effects. Ask whether this is applicable here.
Tips for the appointment
Bring a second person to take notes — it is very hard to listen and write at the same time.
Ask the oncologist to repeat or rephrase anything that is not clear. There are no silly questions.
It is fine to take time before deciding on treatment. Ask what a reasonable decision window looks like for this diagnosis.
