The short answer
What should you ask before colon cancer treatment starts?
Ask first what the treatment is for, and which results the plan is based on. Then ask what each part will do to daily life, where it happens and what it will cost in total. Those few answers explain most of what follows.
The one question to ask first
Ask whether the treatment is given with curative intent, meaning the aim is to remove the cancer completely, or whether the aim is to control it and keep you well for as long as possible. Families often avoid this question. Knowing the answer makes every later choice easier to weigh, from how many side effects are worth accepting to how far to travel.
You do not need to ask everything
No one gets through a long list in one appointment. Pick the five or six questions that matter most to you and ask those clearly. Doctors expect questions, and a good team would rather answer them now than have you stop treatment halfway because nobody explained it. If you think of more at home, ask at the next visit or call.
There is no question too basic to ask. If you did not understand an answer, ask again.Matched to your plan
Which questions fit the treatment you have been offered?
Colon cancer treatment usually means surgery, chemotherapy, or both. In stage 4, drug choice depends on tests of the tumour. Use the card that matches your plan.
Before surgery
CION's surgical oncologists plan the operation, and it is carried out at an accredited partner hospital. Ask about the operation, the stay and the recovery. The page on whether there will be a stoma covers the question most people fear.
Worth asking
- Which part of the colon will be removed?
- Keyhole or open surgery, and why?
- Could I need a stoma, and would it be temporary?
Before chemotherapy after surgery
Chemotherapy after surgery, called adjuvant treatment, aims to clear cancer cells too small to see on a scan. Ask why it is advised for you, how long the course runs and when it starts. The chemotherapy for colorectal cancer pages explain the drugs and side effects.
Before treatment for stage 4
Here the tumour's test results drive the plan. Ask for your MMR or MSI, RAS and BRAF results, and whether liver or lung spots could ever be removed. MSI-high cancers may suit immunotherapy.
Worth asking
- Which results have come back, and which are pending?
- Has a liver surgeon seen my scans?
- What happens if this first treatment stops working?
About daily life and money
Ask whether you can keep working, what to eat, and how often you must come to the centre, which matters if you travel from a district. Ask for a written estimate of the whole course and whether Aarogyasri, Ayushman Bharat or your insurance will cover it.
Not sure whether this applies to you?

In the room
How do you get real answers in a short appointment?
Write the questions down first
Write them in Telugu or English, whichever is easier, with the most important at the top. Hand the list to the doctor if speaking feels hard. Bowel symptoms are awkward to describe, and a written note gets past the embarrassment.
Bring one person who will listen
A son, daughter or daughter-in-law can write down the answers while you talk. Choose the person who will help with treatment at home, so they hear the instructions first-hand rather than second-hand.
Ask for the plan in writing
Ask for the plan, the order of treatments and the next date on paper. Relatives who could not come can then read the same thing, instead of a version that changes each time it is retold.
Ask who to call at night
Before you leave, find out what counts as an emergency and who to call when one happens. A fever during chemotherapy needs attention the same day, not at the next visit.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Did you know
The MMR test checks whether the tumour can repair its own DNA. Its result can change the plan in stage 2 and stage 4, and it can show that relatives may carry an inherited risk. If nobody has mentioned yours, ask before treatment starts.
Being straight with you
What this page cannot tell you
It gives you the questions, not the answers. The answers depend on your pathology report, your scans, your tumour's test results and your general health, and only the team treating you has all of those. If the answers you get do not make sense, a second opinion on the treatment plan is a reasonable next step.
Who this does not apply to
If you were admitted with a blocked or torn bowel, surgery may have happened before anyone could ask questions. That is normal, and these questions still apply to whatever comes next. If the cancer is in the rectum, the plan often includes radiation and different decisions, so start with the rectal cancer pages. If treatment is already finished, your questions are about follow-up instead.
If you are unsure what to ask, call the helpline and describe the plan you were given.Questions we are asked
Common questions before treatment begins
Is it rude to ask my doctor so many questions?
No. Cancer specialists expect questions, and the answers help you stay with treatment when it gets hard. If time is short, ask the most important ones first and ask when you can raise the rest, at the next visit or by phone.
What if I do not follow the medical words?
Say so at the start. Ask the doctor to use plain words, and ask whether someone on the team can explain in Telugu. Ask for the plan in writing so a family member can read it again at home and help you understand it.
Should the patient be in the room, or only the family?
The patient, wherever possible. Treatment needs their consent, and someone who knows why a side effect is happening copes with it far better. Families sometimes want to protect an elder from the word cancer. Talk to the doctor about how to share it gently.
How long can I take to decide?
For planned treatment there is usually time to ask questions, talk at home and even get a second opinion. Chemotherapy after surgery should still start on time, and emergencies cannot wait. Ask your doctor directly how long is safe in your case.
Can I ask what happens if I choose no treatment?
Yes, and it is a fair question. A good answer describes what is likely to happen with and without treatment, in plain words. Hearing it does not commit you to anything. It helps you see what the treatment is really offering.
Should I ask about cost before treatment starts?
Yes. Ask for a written estimate of the whole course, not one cycle or one stay, and what it leaves out. Ask whether your insurance needs approval before admission, and whether a government scheme covers any part. Planning money early prevents a stop halfway.
What should I ask about side effects?
Ask which side effects are common, which are dangerous, and what to do about each. Ask for a written list of warning signs, such as fever, heavy diarrhoea or being unable to keep fluids down, and the number to call for each one.
Can CION answer these if I am treated elsewhere?
Yes. A consultation at CION can go through the plan you were given and answer the questions your team did not have time for. Bring your reports and the plan in writing. Many people then continue with their own team, better informed.
