Feline adenocarcinoma is a form of cancer that originates in glandular tissue. Because there are a number of different locations within your cats body where adenocarcinoma can form, the symptoms, diagnosis and treatment of a feline case of this form of cancer depend almost entirely upon the specific case. Generally, however, adenocarcinomas in the same part of the body present similar symptoms between cats.
Symptoms of Adenocarcinoma of the Pancreas
Adenocarcinoma of the pancreas is one of the most common forms of this cancer in felines. When it takes this form, adenocarcinoma often presents symptoms similar to those of pancreatitis. The most frequently observed of these symptoms include the following:
- Swollen or painful abdominal area
- Vomiting and diarrhea
- Refusal or inability to eat normally
- Lethargy
- Depression
A radiograph or biopsy may show a small mass within the abdomen, but these tests are conclusive in diagnosing adenocarcinoma only about half of the time.
Symptoms of Adenocarcinoma in the Stomach
Another common site for feline adenocarcinoma is the stomach. Cats with this form of cancer oftentimes present symptoms from among the following list:
- Vomiting and diarrhea
- Blood in vomit or in stool
- Dehydration
- Refusal to eat
- Distension of the stomach area
Because warning signs may not present themselves until the cancer has progressed to a reasonable degree, it is important to have your pet examined by a veterinarian at the first sign of any of the symptoms listed above.
Symptoms of Adenocarcinoma of the Mammary Glands
Feline adenocarcinoma can develop in the mammary glands in either male or female animals. It can be difficult to distinguish adenocarcinoma of the mammary tissue with other forms of feline breast cancer, as they tend to display the same set of symptoms:
- Blood, pus or other discharge from the nipples
- Uncommonly swollen or irritated nipples
- Palpable lumps or swellings around the nipples
Siamese cats are more likely than other breeds to develop adenocarcinoma of the mammary glands, but this form of cancer can occur in any cat and at any age.
Symptoms of Adenocarcinoma of the Lungs
Although it is less common than other forms of the disease, adenocarcinomas can form in the lungs. A cat with an adenocarcinoma growth in his lungs will typically show one or more of the following symptoms:
- Difficulty breathing while at rest
- Wheezing
- Coughing
- Lack of energy, particularly while walking or running
If your cat appears to be panting, or if he displays any of these symptoms, take him to a veterinarian right away.
Symptoms of Adenocarcinoma Occurring in the Mouth
Oral cancers have unique symptoms. Generally, these forms of cancer are more easily detected by owners than certain other types. Be on the lookout for the following symptoms:
- Drooling
- Difficulty eating or drinking
- Bleeding or discharge from the mouth
- Vomiting
- Unusual swellings or growths, either visible or palpable
Whatever the form of adenocarcinoma, prompt diagnosis and treatment is essential. Without it, your pet runs the risk of having the cancer metastasize and spread throughout his body, where it can then effect other organs. Certain forms of this cancer are easier to diagnose and to treat than others. If you are in doubt about your cat's health, speak with a veterinarian immediately.
