What is Liver Tumor?

Cancer of the liver most often occurs in older cats who are 10 years of age or older; male cats have a slightly greater risk of developing liver tumors than females. Treatment depends on whether the liver tumor is benign or malignant and what organs are involved.

Liver tumors in cats, also known as hepatic neoplasia, occur when a primary tumor develops in the liver, when cancer develops in the blood cells or lymphoid tissue that involve the liver, or when a different type of cancer metastasizes and spreads to the liver. Primary liver cancer is rare in cats and accounts for less than two percent of all cases. The majority of liver cancer occurs when cancer of the spleen, pancreas or intestinal tract becomes metastatic.

Symptoms of Liver Tumor in Cats

Symptoms may vary depending on if the tumor is benign or malignant and if the tumor has metastasized from another primary cancer in the cat's body. These symptoms include:

  • Vomiting
  • Loss of appetite
  • Weight loss
  • Nausea
  • Diarrhea
  • Excessive thirst (polydipsia)
  • Increased urination
  • Abdominal distension
  • Weakness
  • Lethargy
  • Pale gums
  • Jaundice (yellowing of the eyes and mucous membranes)
  • Breathing difficulty
  • Increased respiratory rate
  • Seizures
  • Disorientation
  • Stumbling


There are several different types of primary liver tumors, including:

  • Hepatocellular carcinoma
  • Hepatocellular adenomas
  • Bile duct carcinomas
  • Mesenchymal sarcoma tumors
  • Neuroendocrine or carcinoid tumors
  • Bile duct adenomas
  • Leiomyoma
  • Hemangioma
  • Bile duct cystadenomas
  • Hepatomas

Causes of Liver Tumor in Cats

There is no known cause of liver tumors. Researchers believe that age could be a risk factor. The older a cat is, the more cell divisions that its body has gone through, increasing the risk of a mutation. Other possible risk factors include consumption or inhalation of chemicals or toxins, chronic inflammation, and hepatotoxicity.

Diagnosis of Liver Tumor in Cats

The veterinarian will need to know the cat's complete health history, which will include what symptoms are present and when the symptoms first began. The veterinarian will examine the cat, feeling for any enlarged lymph nodes or abdominal enlargement and listening to its breathing and heart. Because liver tumors are often asymptomatic until they grow and spread to other organ systems, the tumor may be found during a routine exam.

Several labs will be taken, which will include a complete blood count, biochemical profile, an electrolyte panel and a urinalysis. These labs don't test for liver cancer but can show signs of liver damage or bile duct obstruction, which can lead to further testing. An abdominal ultrasound and chest x-ray will be performed to look for evidence of a tumor or metastasis to the lungs and to eliminate other conditions. To make a definitive diagnosis, the veterinarian will need to do a liver biopsy. This will be done via a needle that is inserted into the liver to remove a sample of fluid or during surgery to remove a small portion of the liver tissue. These samples will then be tested for cancer cells. 

Treatment of Liver Tumor in Cats


Surgery is the preferred treatment for primary liver tumors. Because the liver is regenerative, up to 75 percent of the liver can be safely removed to eliminate the tumor while still preserving function. The cat will be placed under general anesthesia during the surgery. An incision will be made in the abdomen, the tumor will be removed, along with a portion of the liver. The incision will then be closed with sutures. Surgery is normally successful, even for large tumors, when the tumor hasn't spread beyond the liver.


Chemotherapy may be utilized to slow the progression of cancer that has spread to other organs beyond the liver or for the treatment of primary cancers that have metastasized to the liver. Chemotherapy has a variety of side effects, however, and should only be attempted if these side effects can be managed and if regular abdominal ultrasounds indicate that the chemotherapy is effective in shrinking the tumor.


Medications for pain management may be prescribed in order to keep the cat comfortable and free from the pain of the tumor. Antibiotics will also be prescribed after surgery to ensure that infection doesn't occur.

Recovery of Liver Tumor in Cats

When caught early, primary liver tumors have a high success rate after surgery and have a good prognosis. The cat will need to regularly follow up with the veterinarian to monitor the liver for signs of the cancer returning. Cats who have a liver tumor that has metastasized from another primary cancer or have primary liver cancer that has spread have a poor prognosis. The cat will need to be cared for at home and proper care will need to be taken to keep the cat comfortable.

According to his ultrasound report, my 16 year old cat has “multiple large hypoechoic nodules (up to 1.5 cm in diameter) that give his liver an almost Swiss cheese like appearance.” Does this mean he definitely has cancer? Do you think surgery is possible? If not, would chemotherapy be effective?

A hypoechoic nodule or mass is an area or structure which is less dense than the surrounding tissue which doesn’t bounce back as many ultrasound waves giving a darker appearance than a solid mass which would bounce more waves back making a solid white appearance. Without seeing the ultrasound and examining Rocko I cannot comment fully; you should consult with an Oncologist to assist with the diagnosis. Regards Dr Callum Turner DVM

There is a good chance of recovery if there is a solitary liver tumour which can be removed by surgery. Hepatocellular carcinoma has a low speed of spread and can usually be removed easily by your Veterinarian. The type of tumour is important for the overall prognosis; an ultrasound and fine needle aspirate may be useful in determining treatment. Regards Dr Callum Turner DVM

My cat is an 18 y/o male. I took him to the ER after a fall off the bed, fearing he broke his leg or hip. Nothing was broken. Xrays revealed an enlarged liver with what i was told looks like cancer. At his age, i don't think surgery is an option. I can't afford further testing. What do you suggest I do? He has arthritis and i have been giving him buprenorphine for pain management. His appetite has decreased over the years, but he always will eat treats. He's finicky about his water, and I've found that he will drink more now that i give him purified water. Is there anything i can do to prolong his life?

My cat just went in today for a liver mass. They removed 1 mass and 1 lesion , but they couldn't get to the other mass in his liver cuz it was too deep. I'm hoping for the best for my little man. I'm hoping test results come back as benign. Good luck with u'r kitty! Sayin prayers for ya!

Im going through the exact same situation. I thought my cat hurt his leg and find out he has liver cancer. He keeps resting his chin in the water bowl even after a sub q. Please let me know if you find a way to help him. I just wish my cat could walk without falling down. I think then he would have a chance of eating and drinking better. Im holding out hope that he can walk in the next few days.

My cat is 8yo and im really worried im going to loose her. i was told that during the biopsy the mass may get " upset " and inflamation can make her worse. i dont know what do to, what are the chances thigs go wrong ?

There is no real set statistic for things going wrong, but you have to imagine that any potential downside from this is offset by the benefit of biopsy results and more information. Indeed taking a biopsy can be risky but for the most part is it routine and your Veterinarian is informing you (legally) of what may occur in a worse case. I would go through with the biopsy if I was in your position. Regards Dr Callum Turner DVM

With my dear Pandora, she wants ham all the time. Quality over quantity. Give her anything she wants.

Very sorry to hear it. I went through this with a very beloved cat many years ago and I don't think I've ever really gotten over it. You may only have a couple of months with her. Spend all the time you can with her. Give her lots of love. She'll tell you when it's time.

she had a surgery today, planned biopsy, but after opening her it was obvious we are dealing with cancer that overtook the liver. the biopsy was cancelled , she wont be going throught the chemo.. i dont know how much time we got left.

My cat had an ultrasound where a small tumor was found on her liver. My vet said that we need to wait 60 days and recheck that no surgery may be needed. I thought that we should remove the tumor and check for cancer what do you suggest

Your Veterinarian is being cautious and may not want to operate if there are no changes in size and shape over the next two months; some masses just sit there whist others may grow in size. If you have concerns or just elect to have surgery, talk to your Veterinarian that you would prefer surgery and to send the mass for histopathology. Regards Dr Callum Turner DVM

We just had new ultrasound and original mass grew with 2 new tumors. Biopsy was done (aspirated) and now told we may or may not get answers. This is $1300 later. I am very concerned this is likely cancer? Any chance it is nothing? She seems healhty, is on Pred for the weight loss she had 12 months ago that we thought was due to IBD and she responded so well. She does have a lot of urine in the box and foul smelling stool, though firm and normal

Bloody diarrhea

Medication Used

Added today, Prednisone

My Persian female, Pandora, is 17 years old. Three days ago, she began to have foul, bloody diarrhea. Took her to vet and she said colitis. Given antibiotic injection and a packet of water subq. Took her back to the vet today as diarrhea and poor appetite do not seem better. However, bleeding is much better. Asked vet to do abdominal x-ray to clear my mind of "what ifs." Well, she has a 1 /2 to 2 inch lesion on her liver. Belly also full of gas. Now, after a lot of tears, what is best for Pandora. She is precious.

Thank you for your email. I am sorry that Pandora is having problems. Without knowing more about Pandora's lab work and x-rays, I have a hard time commenting on what might be going on with her. The next step for her may be an abdominal ultrasound to identify more clearly what is going on with her liver, and if she has not had blood work done, that would be a good idea. i hope that she has a treatable condition, and does well.

Pandora is about 2 weeks past her diagnosis of liver lesion and two weeks into her Prednisone treatments. Bloody diarrhea, diarrhea at all, are gone. Normal stools and, of course, tremendous appetite. The evidence of weight loss/ dehydration is disappearing. But yet, we still have a liver lesion. I have opted to avoid surgery due to her age and somewhat sluggish kidneys. If this were you, what would you do? P.S. Thanks for the advice ( and yes, she was ultrasounded when the abdominal x-ray showed a mass.)
