Colorectal cancer that has spread to the liver: where to read more | CION Cancer Clinics
Bowel cancer that has spread to the liver is still bowel cancer, so the full detail lives in our colon cancer pages. It is treated with bowel cancer medicines, and in some carefully chosen people the liver spots can be removed. This page explains why, gives a short outline of how the plan is decided, and points you to the right page for each question. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
Where should I read about bowel cancer that has spread to the liver?
Read our colon cancer pages. Bowel cancer that has spread to the liver is still bowel cancer, and the full detail lives in the colon cancer spread to the liver guide. This page explains why, and points you to the right page for each question you are likely to have.
Doctors call these spots colorectal liver metastases. Under the microscope they are bowel cancer cells, not liver cells. They are treated with the chemotherapy and targeted medicines used for bowel cancer, and surgery is planned by teams who know bowel cancer well.
Why this is different from other spread to the liver
Bowel cancer is one of the few cancers where spots in the liver can sometimes be removed with curative intent. That means the operation is done hoping to clear the cancer, in carefully chosen people. Not everyone is suitable, and the decision is detailed. That is why it has its own set of pages rather than a paragraph here.
If your cancer started in the liver itself, this page is not for you. Start with the primary versus secondary guide.A reading guide
Which page answers which question?
Families usually arrive with one of four questions. Each has a page that answers it properly.
What does this spread mean?
Start with metastatic colon cancer explained. It covers what stage four means in bowel cancer, why the liver is the usual first place, and how the plan is built.
Can the liver spots be removed?
Read who is eligible for liver surgery. It explains what the surgeon looks at before agreeing to operate.
The questions it answers
- How many spots, and where they sit
- How much healthy liver would be left
- Whether the cancer is controlled elsewhere
What if surgery is not possible?
Ablation, which destroys a spot with heat through a needle, is one option. Read about ablation for liver metastases. Chemotherapy may also shrink spots enough to make surgery possible later.
Should we get a second opinion?
For a decision this large, often yes. Read about a second opinion on a treatment plan.
Not sure whether this applies to you?
Ask an oncologistIn outline
How is the plan usually decided?
Mapping the spread
A CT or MRI scan of the liver, and often a PET-CT, shows how many spots there are and whether anything lies outside the liver. CION arranges these scans through partner diagnostic centres.
Testing the tumour
The bowel cancer tissue is tested for gene changes such as RAS and BRAF, and for a feature called MSI. These results decide which targeted medicine or immunotherapy may be added.
The tumour board
Medical, surgical and radiation oncologists review everything together. They decide whether surgery comes first, chemotherapy comes first, or surgery is not the right path.
Treatment and review
Most people start with chemotherapy. Scans are repeated to see how the spots respond, and the plan is revisited each time. CION's surgical oncologists assess any operation, and your team will tell you where it takes place.
Commonly believed
What do families often get wrong about bowel cancer in the liver?
"Once it is in the liver, nothing can be done."
That is often not true for bowel cancer. Some people are offered surgery or ablation, and many more are offered treatment that controls the cancer for a long time. What is possible depends on the scans and the tumour tests.
"This is liver cancer now, so we need a liver cancer hospital."
The cells are still bowel cancer cells. The team needs experience with bowel cancer and with liver surgery for spread. Liver cancer treatments designed for cancer that starts in the liver are not the usual answer here.
"If surgery was not offered, the doctor has given up."
Surgery is not right for everyone, and an operation that cannot remove all the spots may do more harm than good. Chemotherapy first is a standard plan, and surgery can be revisited if the spots shrink.
"Removing the liver spots means the treatment is over."
Chemotherapy often continues around the surgery, and regular scans follow for years. Bowel cancer can return in the liver, and finding it early keeps more options open.

On your report
What do the words on the report mean?
- Colorectal liver metastases
- Bowel cancer that has spread to the liver. Often shortened to CRLM on reports and letters.
- Synchronous
- The liver spots were found at the same time as the bowel cancer.
- Metachronous
- The liver spots appeared later, after the bowel cancer was treated.
- Resectable
- The surgeon thinks the spots can be safely removed while leaving enough healthy liver.
- Conversion therapy
- Chemotherapy given to shrink spots that cannot be removed yet, so that surgery may become possible.
- RAS, BRAF and MSI
- Tumour test results that help decide which targeted medicine or immunotherapy may work.
Being straight with you
What this page cannot tell you
It cannot tell you whether your liver spots can be removed, or how your own illness will go. Those answers depend on scans, tumour test results, how well you are and how the cancer responds to the first treatment. Only a team that has seen all of these can answer.
Who this page does not apply to
If the spots in the liver came from the breast, lung, stomach, pancreas, kidney or ovary, the plan is different. Read our secondary liver cancer guide or the page for that cancer. If the cancer started in the liver, it is primary liver cancer and has its own pages.
When to ask more questions
If you have been told surgery is not possible and you are not sure why, ask the team to explain it in plain words. A second opinion from a tumour board is reasonable. Bring every scan on a disc and every report, including the bowel pathology and gene test results.
Call the helpline if you are unsure where to start. Someone will help you arrange a review.Questions we are asked
Common questions about bowel cancer that has spread to the liver
Is bowel cancer in the liver the same as liver cancer?
No. It is bowel cancer that has travelled to the liver, so it is treated as bowel cancer. Primary liver cancer starts in the liver cells and is treated very differently. Your report and biopsy tell the team which one you have.
Why are these pages in the colon cancer section?
Because the treatment follows the bowel cancer. The medicines, the gene tests and the surgical thinking all come from bowel cancer care. Keeping the detail in one place means it stays accurate and you do not read two versions of the same advice.
Can liver spots from bowel cancer be removed?
Sometimes, in carefully chosen people. The surgeon looks at the number and position of spots, how much healthy liver would be left and whether the cancer is controlled elsewhere. Our liver surgery eligibility page explains this in full.
Does chemotherapy come before or after surgery?
It can be either, or both. Some people have chemotherapy first to shrink the spots and test how the cancer responds. Others have surgery first. The tumour board decides the order based on the scans and the tumour test results.
What is ablation, and is it the same as surgery?
Ablation destroys a spot with heat delivered through a needle, usually guided by a scan. It suits some small spots and people who cannot have an operation. CION coordinates ablation through accredited partner hospitals.
Why does the tumour need gene testing?
Results such as RAS, BRAF and MSI decide which targeted medicines or immunotherapy may be added to chemotherapy. They can change the plan a great deal. Ask whether these tests have been done on the bowel tissue before treatment starts.
Will the cancer come back after the liver spots are removed?
It can, which is why regular scans continue for years after surgery. If it returns in the liver, further surgery or ablation is sometimes still possible. Your oncologist will explain your follow-up plan and what to watch for.
Where do we start if we have just been told?
Collect every scan, the bowel pathology report and any gene test results. Bring them to a medical oncologist for review. Call the CION helpline if you are not sure who to see, and someone will help you arrange it.
