Understanding Carcinoid Cancer in Cats
Carcinoid cancer is a rare occurrence in felines, typically affecting cats that have reached seven years of age or older. These tumors are part of a widespread group of tumors known as neuroendocrine tumors that can grow in various regions of the body, including the digestive tract, liver, heart, and lungs in cats. Carcinoid tumors can secrete substances such as serotonin, histamine, and peptides into the bloodstream, leading to various symptoms and clinical signs.
Rare Occurrence in Felines
Carcinoid tumors are relatively rare in both dogs and cats. While they can occur in cats, they are not as commonly diagnosed as in other species. The exact cause of carcinoid cancer in cats is still unknown, and it is not yet fully understood why some cats develop these tumors while others do not (VCA Hospitals).
Common Tumor Locations
When carcinoid tumors do occur in cats, they are typically found in specific locations within the body. The most common tumor locations include the stomach, small intestine, liver, and heart (PetMD). These tumors can vary in size and may affect the normal functioning of the affected organs. The secretion of substances by these tumors can lead to a range of symptoms, including anorexia, vomiting, dyschezia, weight loss, and even heart disease.
To diagnose and treat carcinoid cancer in cats, it is crucial to recognize the signs and symptoms associated with this condition.

Endoscopy: This procedure involves the use of a flexible tube with a light and camera (endoscope) to visualize the gastrointestinal tract, including the esophagus, stomach, and small intestine. It allows for direct visualization of any abnormalities or tumors.
-
Bronchoscopy: In cases where carcinoid tumors are suspected in the lungs, bronchoscopy may be performed. This procedure allows for the examination of the bronchial tubes and lungs using a bronchoscope.
-
Colonoscopy: Colonoscopy involves the insertion of a long, flexible tube with a camera (colonoscope) into the rectum and colon. It allows for the visualization of the large intestine and the detection of any abnormalities or tumors.
-
Capsule Endoscopy: This procedure involves swallowing a small capsule containing a camera that takes images of the digestive tract as it passes through. It is particularly useful for examining the small intestine, where gastrointestinal carcinoid tumors may be located.
Testing and Examination
In addition to diagnostic procedures, several tests and examinations are employed to aid in the diagnosis of carcinoid cancer in cats. These tests help in the process of elimination and provide additional information for a definitive diagnosis. Some common tests and examinations include:
-
Biochemical Tests: Blood tests may be conducted to measure levels of certain hormones, such as serotonin and chromogranin A, which can be elevated in cats with carcinoid tumors.
-
Urine Analysis: Urine samples may be analyzed to assess the presence of certain substances associated with carcinoid tumors, such as 5-HIAA (5-hydroxyindoleacetic acid), a metabolite of serotonin.
-
Ultrasound Imaging: Ultrasound imaging is a non-invasive technique that uses sound waves to create images of the internal organs. It can help identify abnormalities or masses that may indicate the presence of carcinoid tumors.
-
Biopsy: A biopsy involves the collection and examination of a small tissue sample from a suspected tumor. This procedure provides a definitive diagnosis by allowing for detailed histological and immunohistochemical examinations. Electron microscopy and immunohistochemical stains can further confirm the diagnosis.
By utilizing a combination of diagnostic procedures, testing, and examinations, veterinarians can accurately diagnose carcinoid cancer in cats.
