Types of Liver Cancer in Cats
Types of Liver Cancer in Cats

#1. Hepatocellular Carcinoma.

Hepatocellular or Hepatomas is a type of cancer condition that stems directly from the liver cells, called “hepatocytes”. Hepatocellular carcinoma is the second most common liver tumor that develops in cats. Most hepatocellular carcinoma is of a massive form.

#2. Hepatocellular Adenomas.

Hepatocellular Adenoma is a benign tumor that occurs in the liver cells. It results from an overgrowth of epithelial cells which are involved in secretion in the body. This type of tumor is less common in cats.

#3. Bile Duct Carcinomas.

Bile duct carcinoma is the major type of liver cancer that affects cats. The occurrence is cut across all cat breeds, but female cats are at a high risk to develop this disease than male cats. Also, cats that are 10 years of age or older are at a high risk of developing this disease.

#4. Bile Duct Adenomas.

The Bile duct adenomas otherwise known as also known as biliary or hepatobiliary cystadenomas is also a common health issue that affects cats, and it accounts for more than 50% of all feline hepatobiliary tumors. Male cats may be predisposed to female cats.

#5. Hemangioma.

Hemangiomas are intermittent tumors that occur mostly in adult cats and most often develop on the head, legs, and abdomen. They have a resemblance to the blood vessels, and some even look like blood blisters.

Your veterinarian should be able to diagnose if your cat has liver cancer or other Liver Diseases during a routine wellness check.

A thorough examination will be done whereby the vet doctor will be feeling for any enlarged lymph nodes or abdominal enlargement as well as listening to its breathing and heartbeat.

Blood tests and other lab investigations will be done including a complete blood count, biochemical profile, an electrolyte panel, and a urinalysis.

All of which will help detect any abnormalities such as liver damage or bile duct obstruction, which can lead to further testing.

Abdominal scan and Abdominal or chest x-ray will be performed to look for evidence of a tumor or metastasis to the lungs and as well to eliminate other conditions.

For further investigation, a liver biopsy will be performed. This will help your veterinarian to come up with a more definitive diagnosis.

The process is done via a needle that is inserted into the liver to remove fluid samples.

Also, samples of the liver tissue can be collected during surgery. These samples are taken to the lab to be tested for cancer cells.

The next phase to discuss is the treatment options for Liver Cancer in Cats. Once a cat is diagnosed with hepatocellular carcinoma, prompt treatment is mandated to decrease the chance of cancer spreading to other organs.

The outcome of the treatment depends on the cat’s condition, and the type of treatment employed.

#1. Surgical Removal.

Lobectomy is the surgical removal of the tumor when it remains benign and not yet metastasize to other body areas.

Singular masses can be easily removed and even when the tumor is subtle, a large chunk of the liver can be excised, allowing a great amount of cancerous tissue to be taken out.

However, in the case of malignancy, surgical removal can only do little except it is performed alongside chemotherapy.

#2. Systemic Chemotherapy.

Over the years, chemotherapy plays a vital role in cancer treatment, especially when cancer has spread throughout the body, chemotherapy is the best treatment option.

Another method of treatment is Glue Injection otherwise known as chemoembolization.

This is a process involves a catheter fed directly to the affected liver lobe and a type of glue and chemotherapy is injected into the blood vessels that feed the tumor.
