Questions to Ask Your Oncologist Before Chemotherapy
For anyone who has been told chemotherapy is the plan, and for the relative or friend going along, in the days before the first infusion. These questions to ask your oncologist before chemotherapy follow the order the conversation with the oncologist or chemotherapy nurse tends to take: the plan and its aim, infusion day, side effects, infection and when to call, daily life, and costs and what comes next. Each has a note on what a good or a worrying answer sounds like or what to do with it, and none of it is medical advice.
The questions
Each question, and why to ask it
The plan
What is this chemotherapy meant to do: cure the cancer, shrink it before surgery, lower the chance of it coming back, or keep it under control?
Why ask it
The same drugs can be given for any of those four reasons, and the aim decides how much discomfort is worth pushing through. Write the answer down in the oncologist's own words. If it is 'control', ask what a good result would look like for you.
Which drugs will I be getting, and can you write down the name of the regimen?
Why ask it
Regimens often go by an abbreviation built from the drug names, and that abbreviation is what a pharmacist, an insurer or an emergency doctor will want from you. Get the information sheet for each drug as well, in place of a general chemotherapy leaflet.
How many cycles are planned, and how long is each one from one treatment day to the next?
Why ask it
A cycle is the treatment plus the recovery days after it, so 'six cycles' tells you little until you know the length of one. Have the dates put on a calendar, and treat the last one as penciled in.
What will you measure to tell whether the chemotherapy is working, and after which cycle?
Why ask it
Listen for a named test, such as a scan, a blood marker or an exam, and a point in the schedule. When chemotherapy follows surgery there may be nothing visible to measure, and it helps to hear that now so a stretch without scans does not feel like being forgotten.
How much does chemotherapy improve my chances compared with not having it?
Why ask it
Some oncologists can put a figure on it for someone in your position, and others will tell you the evidence only supports a rough range. Either way, have it put as a count of people ('of twenty patients like me, how many does it help?'), which is easier to weigh than a percentage. If figures would only frighten you today, ask for the answer in words.
Why this combination for me, and not a gentler or a stronger one?
Why ask it
A good answer points at something about you: what the tumor tests showed, the stage, your age, how your heart and kidneys are doing. 'It is the standard' may well be true, and the follow-up is what about a patient would make them pick something else.
Is the chemotherapy on its own, or alongside radiation, immunotherapy, a targeted drug or hormone pills?
Why ask it
Each added treatment comes with its own calendar, its own side effects and often its own team. One page that shows what happens in which week, with a doctor's name beside each part, saves a lot of phone calls later.
Do I need any tests before the first cycle, such as a heart scan, a hearing test or extra blood work?
Why ask it
Some drugs call for a baseline reading so that a later change can be spotted. Find out which apply to yours and who books them: a start date can slip while everyone waits on a test nobody arranged.
What would make you lower a dose, delay a cycle or change the drugs?
Why ask it
Delays and dose changes are common, often because of blood counts or a side effect, and they frighten people who were never told to expect them. The part worth pinning down is whether a week's delay would matter to the result in your case.
Infusion day
Will every treatment be at this center, and will any of them mean a night in the hospital?
Why ask it
Some regimens are given in a chair in a few hours and others mean being admitted, and the answer can differ from one cycle to the next. Get the unit's name and address for the first day in writing, with where to park and which entrance to use. Nobody wants to begin cycle one lost in a parking garage.
How will the drugs be given: an IV in the arm, a port, a PICC line, pills at home, or a pump I wear?
Why ask it
The route shapes daily life more than people expect. A line needs flushing and dressings, a port needs a small procedure, and pills put the timing in your hands. It is fair to ask why this route was picked for you, and whether you get a say.
If I need a port or a line, who puts it in, when, and how do I look after it at home?
Why ask it
Get the care instructions in writing before the procedure: showering, swimming, lifting, seat belts, and what redness or swelling means. Find out too who takes it out, and how long after the last cycle.
What happens on a treatment day from the moment I check in, and how many hours should I allow?
Why ask it
The answer is usually a sequence: a blood test, a wait for the result, medicines beforehand, then the infusion itself. Get the figure for the first day separately, since it often runs longer than the rest, and book the ride and the childcare around that one.
Should I eat, drink and take my usual medicines as normal on the morning of treatment?
Why ask it
The answer depends on the drugs and on the center, and it is rarely in the leaflet. Go through your morning pills by name, especially anything for blood pressure, diabetes or thinning the blood, and check whether to arrive having eaten.
Will I have blood tests before every cycle, and what result would stop treatment going ahead that day?
Why ask it
Knowing the cutoff in advance makes a postponed session less of a shock. If you travel far, ask whether the blood can be drawn the day before somewhere closer to home, so you are not turned around at the door.
What medicines will I be given before the infusion, and will any of them make me drowsy or wired?
Why ask it
Some of what people put down to chemotherapy comes from the medicines given with it: an antihistamine can make you sleepy and a steroid can keep you awake. The answer also settles whether you can drive yourself home.
What does a reaction during the infusion feel like, and what should I tell the nurse right away?
Why ask it
Which sensations matter depends on the drug: itching, flushing, a tight chest and burning at the needle site are the sort of thing to have named for yours. Infusion nurses would much rather be called over for nothing than hear about it afterward, so find the call button before the IV starts.
Can someone stay with me in the infusion room, and what should I bring?
Why ask it
Some units welcome one companion and some none, and the policy can change at short notice, so check again the week of your first session. The nurses also know the practical list: layers, a charger, food you can face and something to do that needs no concentration.
Will I go home with a pump, an injection or pills to take, and who shows me how to manage them?
Why ask it
A demonstration before the day is worth more than a leaflet after it. Leave with a written timetable and the number to call if a pump alarms, a dose is missed or you are sick soon after a pill.
Side effects
Which side effects are most likely with these particular drugs, and on which days of the cycle do they usually peak?
Why ask it
Side effects belong to the drug, not to chemotherapy in general, so steer the answer away from the full leaflet and toward your regimen. A rough day-by-day pattern lets you put the bad days where they do least harm and line up help for them.
What do I take for nausea, on what schedule, and what is the next step if it does not work?
Why ask it
The most useful answer is a prescription you can fill before day one, with the timing spelled out and a backup medicine already named. If you are told to wait and see, ask what happens if the nausea starts on the first night, and how long to put up with it before calling.
Will these drugs make my hair fall out, and is scalp cooling offered here?
Why ask it
The answer for your regimen will be one of three: no loss, thinning, or all of it, and the team can usually say in roughly which week. Scalp cooling is offered for some drugs and some cancers and not others, and it can add time and cost to every session, so it has to be settled before the first infusion.
Could any of these drugs cause numbness or tingling in my hands and feet, and when should I report it?
Why ask it
Not every drug does this, so a plain no is a real answer. If yours can, find out whether the team wants to hear at the first tingle or at the next visit, and say now if your living depends on your fingers, as a guitarist's, a typist's or a carpenter's does.
What can I do about mouth sores, taste changes and bowel trouble if they turn up?
Why ask it
These rarely get airtime in the consent conversation and can take over the day when they arrive. Three things to leave with: what to keep in the house from the start, which mouth rinse the team prefers, and how many days of diarrhea or constipation is too many.
Does the tiredness build up from one cycle to the next, and what helps with it?
Why ask it
The honest answer is often a pattern: a few flat days in each cycle, with the later cycles heavier than the first. Tiredness can also have a treatable cause such as low red cells, so find out what level of exhaustion the team wants reported and not slept off.
People talk about 'chemo brain': is trouble concentrating or remembering things likely on these drugs?
Why ask it
Oncologists hear the phrase often and will know what you mean. If it is likely on your drugs, ask whether it tends to lift once treatment ends, and plan around it: lists, a pill organizer, a second person at appointments. Low mood and broken sleep belong in the same conversation, along with who at the center you can talk to.
Could these drugs affect my heart, hearing or kidneys in a way that lasts, and how will you watch for it?
Why ask it
Lasting risks differ from drug to drug, so this is a question about yours and the monitoring that goes with each one. A reassuring answer names the test and how often it is done. Comfort with no test attached deserves a second question.
How long after the last cycle do the side effects usually take to clear?
Why ask it
It is easy to expect to feel normal the week after the final infusion and to be discouraged when that does not happen. A range for your regimen, with which effects go first and which hang on, gives you something to plan a return to work around and something to tell the family.
Infection and when to call
What temperature means I call right away, and which number works at three in the morning?
Why ask it
Get the exact figure, the exact phone number and the words to say when someone picks up. Put all three on the fridge and in the phone of whoever lives with you. Check too whether to take anything for the fever first or to leave it alone until you have spoken to the team.
Besides fever, which symptoms mean a same-day call, and which can wait until the next visit?
Why ask it
Two lists on paper is the goal. Bleeding, vomiting that will not stop, a swollen arm or leg, breathlessness and pain around a port are the kind of thing that tends to land on the urgent one, but your drugs decide it, so have the nurse write yours.
If I have to go to an emergency room, what do I tell them, and should I carry anything?
Why ask it
Many centers hand out a card or letter that names the drugs and explains why a fever during chemotherapy needs quick attention. If yours has one, it lives in your wallet from day one. The other half of the answer is which hospital the team would prefer you went to.
Who is my day-to-day contact, and how quickly should I expect a reply to a message?
Why ask it
Often it is a chemotherapy nurse or a nurse line, and meeting that person before the first session is worth the ten minutes. Settle what belongs in a portal message and what needs a phone call, so that an urgent question does not sit in an inbox over a weekend.
On which days of each cycle will my blood counts be lowest, and what should I do differently then?
Why ask it
Many regimens have a predictable low stretch, and knowing the dates lets you plan crowds, visitors and appointments around it. Precautions are a matter of local policy, anywhere from ordinary hand washing to avoiding certain foods and places, so get this team's list and not the internet's.
Will I be given injections to boost my white cells, or antibiotics to keep at home?
Why ask it
Whether these are part of the plan depends on the regimen and on you, so a no is not a bad sign in itself. If it is a yes, the details to get are who gives the injection, on which day, what it feels like afterward and whether it is billed separately.
Which vaccines should I have before starting, and are there any I should not have during treatment?
Why ask it
Timing matters and the rules differ by type of vaccine, so get names and dates from the team instead of a general yes. The same question applies to the people you live with, including children due their routine shots.
Should I see a dentist first, and what do I do if I need dental work mid-treatment?
Why ask it
Some teams want a check-up and any overdue work finished before the first cycle, because a mouth infection is harder to deal with once counts are low. If something comes up once treatment is under way, find out whether your dentist should call the oncology office before touching it.
Daily life
Will I be able to keep working on this regimen, and which days of each cycle should I plan to be off?
Why ask it
Get the pattern for your regimen, then get it in a letter you can hand to your employer. What you are owed in sick leave, job protection or disability pay is set by where you live and who you work for, so let the center's social worker walk you through the local rules before you promise anyone anything.
Is there anything I should not eat or drink on these drugs, including alcohol and grapefruit?
Why ask it
Some restrictions come from the drug and some from low blood counts, and the second kind may apply only on certain days. If eating gets hard, the team will want to know: find out how much weight loss counts, and whether a dietitian is part of the service.
Can you check my other medicines, supplements and herbal products against these drugs?
Why ask it
Put everything in a bag and bring it: painkillers, antacids, vitamins, anything from a health food store. The pharmacist is often the person who does this check, one product at a time. Before you leave, find out which pain and fever medicines you may reach for without phoning first.
Can I keep up my usual exercise during chemotherapy, and is there anything to avoid with a port or on low-count days?
Why ask it
Say what you do now, whether that is a daily walk, swimming, a gym or a physical job, and get an answer for each. Pools, contact sports and heavy lifting are the ones that tend to get a 'depends', on the line you have and where you are in the cycle.
If I might want children later, what needs to happen before the first dose?
Why ask it
Of everything on this list, this has the hardest deadline: storing eggs, embryos or sperm is generally something done before treatment starts. Push for a referral this week, and for what it costs and whether it would delay the start. It applies to men too, and to anyone who has not made up their mind.
Do my partner and I need to use contraception during treatment, and for how long afterward?
Why ask it
Hardly anyone raises it, and chemotherapy nurses answer it every week without embarrassment. The instruction is usually about avoiding a pregnancy, whichever partner is being treated, with a time frame that runs past the last cycle. If you are pregnant or might be, say so before anything else is planned.
Do the people I live with need to take any precautions in the days after each dose, with the bathroom, laundry or spills?
Why ask it
Traces of some drugs leave the body in urine, vomit and other fluids for a while after treatment, and each center has its own handling rules. Get them in writing, and bring up pregnant relatives, small children and pets by name, plus where to keep any pills and how to get rid of them.
I have a trip or an event on these dates: can the schedule work around it?
Why ask it
Bring the dates on paper. There is most room to move a cycle before the bookings are made, and the oncologist can say whether your event would land in a low-count stretch. For a trip, the extras are whether flying is fine, how far from a hospital is too far, and what letter a travel insurer would want.
Will I need someone to drive me, stay overnight or help at home, and for how many days each cycle?
Why ask it
Relatives want to help and need dates to do it. Plan the first cycle on the cautious version and loosen it once you have seen how you respond. If you live alone or a long way off, say so, and ask what the center can arrange or who it can point you to.
Costs and next steps
What will each cycle cost me, counting the drugs, the infusion visit, blood tests and the medicines I take home?
Why ask it
Nobody can answer this from a general price list: it turns on the health system or insurer you are under and on the exact drugs. The oncologist may not know the figure. The question for them is who does, and whether you can sit down with that person before the first infusion.
Does anything need approving by my insurer or health service before we start, and who is handling that?
Why ask it
Where prior approval exists, a missing one can hold up a first session or leave a bill behind it. You want a name for who submits it, a usual turnaround, and how you will hear it has gone through. Under a public system the question becomes whether every drug on the plan is funded.
If I cannot afford this, who do I tell, and what help has there been for other patients here?
Why ask it
Say the figure that worries you out loud; oncologists hear it often and would sooner know than have you skip a dose. The person to meet may be called a financial counselor, a patient navigator or a social worker. Help can mean a lower drug bill, a travel grant or free parking, and what exists depends on where you are.
Is there anything in the consent form I should go through with you before I sign it?
Why ask it
A consent form generally sets out the aim, the drugs and the risks, and it is easy to end up signing it in a hurry on the first morning. A copy to read at home changes that. Have the oncologist point to the two or three risks they take most seriously for you.
When do I see you again after the first cycle, and what will we go over?
Why ask it
Book it before you leave. That visit is where the first cycle's side effects get turned into changes for the second, so keep a short daily note of what happened and when, and bring it along.
What happens after the last cycle: scans, surgery, more treatment, or follow-up visits?
Why ask it
Knowing what comes next stops the final infusion from feeling like a cliff edge. The details that matter are who is in charge of your care from then on, how often you are seen in the first year, and who you call in between.
Getting ready for the first cycle
Practical guidance for the conversation itself
Before the pre-chemotherapy appointment
Find out who the visit is with
Some centers hold a separate teaching session with a chemotherapy nurse or pharmacist, and some fold everything into one appointment with the oncologist. Ask when you book. Questions about the aim, the choice of drugs and the numbers belong with the oncologist. The nurse is usually the better person for infusion day, side effects and who to phone.
Mark the ones that cannot wait
A few answers have to be in hand before the first infusion: fertility, the consent form, anything needing approval, and the temperature and phone number for an emergency. Put those at the top. Most of the daily life questions can be asked again after the first cycle, when you know how you respond, and no single visit has room for the whole list.
Bring the bag and the calendar
Put every medicine, vitamin and supplement you take in a bag, or photograph the labels. Bring a calendar as well, with work deadlines, school dates, trips and family events on it, because the schedule is being set at this visit and it is much harder to move later.
Take someone and hand them the pen
Decide before you go in who is writing. Ask at the start whether you may record the explanation on your phone; many clinicians agree, and centers have their own rules. If nobody can come, ask whether a relative can listen in by phone for the part about side effects and when to call.
Say how much you want to know
Some people want every number and others want the plan and the dates. Tell the oncologist which you are, and that it may change. If the patient and the relative want different amounts of detail, agree beforehand who asks about outlook, and whether the patient wants to be in the room for it.
Treating the first cycle as a trial run
Set the house up before day one
Fill the prescriptions you were given, check that the thermometer works, and put the after-hours number where everyone in the house can see it. Stock a few plain foods and drinks you can usually face when you feel sick. It is easier to do this the week before than the evening after.
Keep one line a day
Each day of the first cycle, note your temperature if the team asked you to take it, what you managed to eat, any symptom and what you took for it. A notebook by the bed is enough. By the end you have a map of your own cycle, which is more use to you than any general description.
Bring the notes to the next visit
The appointment before cycle two is where the plan gets tuned: a different nausea medicine, an extra day off, a changed dose. Read out the worst three days from your notes instead of saying it was 'not too bad', and ask what can be done about each.
Tell people the pattern once you know it
After one cycle you can usually say which days you will want company, which days you will want to be left alone, and when a meal dropped at the door would help most. Friends and relatives find a date and a task much easier to act on than an open offer.
Making the call when something is wrong
Keep the numbers in three places
The daytime line, the after-hours line and the name of the regimen should be in your phone, in the phone of someone you live with, and on paper at home. Check before the first infusion that the after-hours number is answered at night, and ask who it is that answers.
Have five facts ready
Whoever answers will want the names of your drugs, the date of your last treatment, your temperature and when you took it, what the symptom is, and since when. Write those down before you dial if you can. It shortens the call and gets you a clearer instruction.
Do not wait to be polite
People put off calling at night or over a weekend because they do not want to bother anyone. The team gave you the number for exactly those hours. If you are unsure whether something counts, that is a reason to call and ask, and the nurse can tell you if it will keep until morning.
If you are sent to an emergency room
Say at the front desk that you are having chemotherapy and when the last dose was, and show the card or letter if your center gave you one. Ask the oncology team whether they will phone ahead. Take your medicine list and the notebook with you.
Agree who can call for you
There may be a day when you feel too ill to make the call yourself. Ask the center what it needs in order to talk to a relative about your care, since the rules on that differ from place to place, and get it set up before treatment starts.
Where the conversation goes wrong
Asking about chemotherapy in general
What happened to a neighbor, or what a forum describes, was probably a different set of drugs for a different cancer. Start every side effect question with 'on my regimen' and you will get a shorter, truer list.
Nodding through the drug names
The names are long and said quickly. Stop the oncologist and ask for them written down, with the abbreviation for the regimen. Everything you read or ask later depends on having them right.
Leaving money for the last minute
Cost is a question people are often embarrassed to raise, and it can take the longest to sort out. Ask early in the visit who handles it, so the oncologist's time goes on the treatment and the financial conversation gets its own appointment.
Playing down side effects to stay on schedule
Some patients underreport because they are afraid a dose will be cut or a cycle delayed. Ask the oncologist now how they weigh a side effect against keeping to the plan. Hearing their reasoning in advance makes it easier to be honest in week three.
Treating the first plan as fixed
Dates move, doses change and medicines for side effects get swapped. That is the plan being adjusted to you. At each visit ask what has changed since last time and why, and update your own written copy.
