Was the tumor called inoperable, or were you offered only chemotherapy? Show the images to a surgical oncologist — I will say whether there are grounds to consider surgery.

Operability is assessed by a surgeon
I operate together with a team of surgical oncologists, so I look at your images with one question: whether the tumor can be removed completely, by which approach, and what else is needed for that.
Complex liver surgery
Together with the team, I perform liver operations for multiple metastases under the guidance of a navigation system, as well as simultaneous laparoscopic procedures on the bowel and the liver — through small punctures, when this is possible.
Laparoscopic and open surgery
I perform operations by both approaches, so I choose the one that suits your particular case. For small lesions in the liver there is radiofrequency ablation — destroying the tumor with heat without cutting into the liver.
A plain answer
If surgery will not bring benefit or the risk is too high, I will say so directly and explain why. A second opinion is needed so that you understand your situation, not so that you hear something pleasant.
Direct contact with me
Calls to my mobile number and messages come to me personally, with no call center. If I did not answer, I am in surgery: I will call back within 24 hours.
Science, not only practice
A PhD thesis and scientific articles — including on radiofrequency ablation of colorectal cancer metastases in the liver. I treat according to current international guidelines and know what they are based on.



The second opinion is given by me, Kateryna Valikhnovska, MD, surgical oncologist. I review your CT and MRI images, the histology report and medical records and answer one question: whether there are grounds to consider surgery. A second opinion does not overrule your doctor’s decision — it adds a surgeon’s view to it. You can come in person in Kyiv or contact me remotely.
When to get a second opinion
People seek a second opinion before a serious decision or when the first answer left no hope of surgery. It makes sense to show the documents to a surgeon if:
- you were told that the tumor is inoperable;
- only chemotherapy was offered, and you want to understand whether surgery is possible — now or after the course;
- liver metastases were found, and you were told there are too many to operate;
- the conclusion about inoperability was made several months ago, and you have had treatment since then;
- a major open operation was proposed, and you want to know whether a laparoscopic approach is possible;
- a recurrence appeared after surgery, and it has to be decided whether to operate again.
Asking for a second opinion is normal. It does not mean distrust of your doctor: this is a decision on which all further treatment depends.
Why “inoperable” is not always final
The conclusion that a tumor cannot be removed depends on several things, and some of them change over time.
- The tumor may have responded to treatment. After chemotherapy, lesions sometimes shrink to a size at which surgery becomes possible. So a conclusion made several months ago is worth checking against recent images.
- The organ can be prepared for surgery. For liver metastases this is, for example, portal vein embolization, after which the healthy part of the liver grows, or an operation in two stages.
- What matters is not only the number of lesions but also what will remain. For liver metastases the main question is whether enough healthy tissue will be left after their removal and how the lesions are located relative to the major vessels and bile ducts.
- Operability is a surgical question. If the conclusion was not made by a surgeon, it makes sense to show the images to someone who operates.
At the same time, a second opinion is not a promise of surgery. Sometimes I confirm my colleagues’ conclusion: surgery will not bring benefit or the risk is too high. Then I explain why.
How to get a second opinion
- RequestYou call or leave a request on the website. We agree on the format: an in-person appointment or remotely.
- DocumentsYou bring or send the images, the histology report, medical records and the conclusion you disagree with.
- Review of imagesI look at the CT and MRI images themselves: how the tumor is located relative to vessels and neighboring organs, and what has changed after treatment.
- ConversationI explain what I see, whether there are grounds to consider surgery and what is missing for a decision. I answer questions — yours and your family’s.
- Next stepsIf there are grounds — further tests and, in complex cases, a tumor board. The final decision on surgery is made after an in-person examination.
How to send documents if you are in another city or abroad is described on the page “Online Oncologist Consultation”.
What to prepare
- CT, MRI or PET-CT discs — the most recent and the previous ones, to show how the tumor has changed;
- the histology report and, if available, the blocks and slides;
- treatment records: chemotherapy regimens and number of courses, radiation therapy, operative reports;
- the doctor’s or tumor board’s conclusion stating why surgery is not possible;
- recent blood tests, including tumor markers if they were measured.
You can also come with the documents you already have — I will tell you what else is needed.
What the answer may be
Surgery is worth considering
Next come an in-person consultation, further tests and, if the case is complex, a tumor board. After that we make the decision.
Possibly, after preparation
First chemotherapy or preparation of the organ, then new images and a reassessment.
Based on the available records, no grounds for surgery at present
This is a preliminary conclusion: I explain why, what information is missing and what changes would make it worth returning to the question. The final decision follows an in-person examination.
In every case I explain what the conclusion is based on and what the next steps are. While a preliminary diagnosis is being formed, I give my answer orally; a written opinion follows once all the additional tests recommended by the protocol have been completed. The final approach is determined after an in-person examination.
Frequently asked questions
I was told there are too many liver metastases. Does it make sense to contact you?
Yes. For colorectal metastases, the number of lesions in itself is not a contraindication to surgery. What is assessed is how they are located relative to the vessels and bile ducts, whether enough healthy liver will remain and whether there is spread beyond the liver.
Which images are needed — old or new?
Both. Recent ones show what is happening now, previous ones show how the tumor has changed. If the last examination was a long time ago, I may ask you to repeat it.
Can I get a second opinion online?
Yes, I often consult remotely — based on images and medical records. But the final decision on surgery is made after an in-person examination.
Will my doctor be offended?
A second opinion does not automatically overrule your doctor’s decision. It is needed so that before a serious step you also hear a surgeon’s assessment; sometimes it is a reason to revisit the treatment plan.
If surgery is possible, who will operate?
I operate together with a team of surgical oncologists. In complex cases the decision on surgery is made by a tumor board — together with medical oncologists and radiologists.
What if your opinion matches the first one?
Then you will have two independent assessments that agree. I will explain why surgery is not indicated and what could change that.
How much does a second opinion cost?
The in-person consultation at which I review the images and give a second opinion is free of charge.
How long does it take?
The consultation lasts 30–60 minutes, depending on the complexity of the case and the number of documents. I respond to a request or a missed call within 24 hours.
If surgery is possible: six steps of support
A second opinion can be the start of personal support from a surgical oncologist: from the treatment plan to a year of follow-up after surgery.
- Step 1 you are here
Review of the clinical situation: all examination materials, CT and MRI discs, medical history.
- Step 2
Discussion of the case by a multidisciplinary team with oncologists, medical oncologists and radiologists.
- Step 3
Surgery according to international protocols together with a team of surgical oncologists.
- Step 4
The early postoperative period under the ERAS enhanced recovery protocol.
- Step 5
Deciding on further management and support during the chemotherapy stage.
- Step 6
Advisory support for a year: monitoring test results and reviewing CT and MRI discs.
