Adenocarcinoma is a malignant neoplasm, making up about 75 percent of all primary lung tumors in cats. Adenocarcinoma grows rapidly and metastasizes to distant parts of the body and organs, including the brain, eyes, bones, and lymph nodes. Like other malignant tumors, adenocarcinoma of the lungs is usually seen in older animals (more than ten years). This type of carcinoma is relatively rare in cats, with no known breed disposition.
Most symptoms are related to the respiratory system, but in cases of metastasis the symptoms vary depending upon the location of the metastasis in the body. Following are some of the symptoms seen in patients with lung adenocarcinoma:
You will need to give a thorough history of your cat's health, including a background history of symptoms. After taking a detailed history and performing a thorough physical examination, your veterinarian will order various laboratory tests, including a complete blood profile, a chemical blood profile, a complete blood count, and X-ray studies.
Thoracic (chest) radiographs are the most important tool in diagnosing this condition in pets. An ultrasonography, computed tomography (CT) scan, and magnetic resonance imaging (MRI) may also be used in some patients to confirm diagnosis. The CT scan and MRI may also help in determining the possibility of metastasis of the tumor into other parts of the body.
