Feline cancer can often be difficult to detect due to cats’ ability to hide their illnesses. However, blood tests can provide valuable information in diagnosing cancer in cats. This article will explore the different types of blood tests that can be used to detect cancer, the importance of blood tests in diagnosing feline cancer, and what to expect during a blood test appointment. By understanding the role of blood tests in diagnosing cancer in cats, pet owners can take an active role in ensuring their feline friend receives the proper care and treatment.
What are Blood Tests for Cancer in Cats?
There are several blood tests that can be used to detect cancer in cats. Some of the most common tests include:
Complete Blood Count (CBC)
Blood Chemistry Panel
Tumor Markers
Complete Blood Count (CBC)
A CBC is a basic blood test that is often the first step in diagnosing feline cancer. This test measures the number of red blood cells, white blood cells, and platelets in the blood. It can show if the cat has anemia, infection, or inflammation, which can be indicative of cancer.
Blood Chemistry Panel
A blood chemistry panel is a comprehensive test that evaluates various organ functions and the levels of specific substances in the blood. This test can help determine if the cat has liver, kidney, or pancreatic cancer, as well as other conditions.
Tumor Markers
Tumor markers are substances that are produced by cancer cells and can be detected in the blood. These markers are specific to certain types of cancer and can provide valuable information for the diagnosis of feline cancer.

How do Blood Tests Work?
Blood tests for cancer in cats are simple and non-invasive. A small amount of blood is taken from your cat, usually from a vein in the leg or neck, and sent to a laboratory for analysis. The results of the test can provide important information about the presence of cancer in your cat.
Common Cancers in Cats
There are several common types of cancer in cats, including lymphoma, squamous cell carcinoma, and feline leukemia virus. Blood tests can help to detect these cancers early, which is important for successful treatment and recovery.

Importance of Regular Blood Testing
Regular blood testing is important in the management of cancer in cats. Blood tests can help to detect cancer early, monitor the progress of treatment, and ensure that your cat is receiving the appropriate care. If cancer is detected early, your veterinarian will be able to start treatment right away, which can improve the chances of recovery. In addition, regular blood tests can help to identify any changes in your cat’s health, such as a decline in organ function or an increase in certain proteins that are associated with cancer.
What to Expect During a Blood Test
Blood tests for cancer in cats are relatively simple and non-invasive. Your cat will need to be relaxed and calm for the test, so it is best to bring them to the veterinary clinic in the morning, when they are well-rested. The blood test will be performed by a trained technician or veterinarian, and a small sample of blood will be taken from your cat. Your cat will likely feel a small pinch or sting during the test, but the procedure is over quickly and they will be able to return home with you right away.
