Plain-English summary
A group of 86 cats with confirmed lung tumors showed common symptoms like weight loss, lethargy, and breathing problems. Many of these cats had visible masses in their lungs on X-rays, and some had fluid buildup. The tumors were mostly found in the lower parts of the lungs and often spread to other areas. The study suggests that if your cat has ongoing symptoms like these, a chest X-ray could help identify any hidden lung tumors. Unfortunately, the outcomes for these cats varied, and many had advanced disease at the time of diagnosis.

Abstract
OBJECTIVE To classify histologic type and morphology of primary lung tumors in cats, to describe clinical findings in these cats, and to determine whether clinical findings were associated with histologic type or morphology. DESIGN Retrospective study. ANIMALS 86 cats with histologically confirmed primary lung tumors. PROCEDURE Medical records for cats treated between 1979 and 1994 at any of 14 participating veterinary referral hospitals were reviewed. RESULTS Weight loss, lethargy, and dyspnea were the most common clinical signs. Solitary or multiple pulmonary masses were seen on radiographs from 53 of 79 cats; effusion was seen on radiographs from the other 26. In 45 cats, tumors involved a single lung lobe. Caudal lung lobes were more commonly affected than were cranial lung lobes. Sixty-five cats had metastases. Tumors were classified as bronchial (n = 65), bronchiolar-alveolar (9), or other (12) and as poorly differentiated (59), moderately differentiated (20), or well differentiated (7). Breed, age, sex, weight, clinical signs, duration of clinical signs, and radiographic findings were not associated with histologic type or morphology. CLINICAL IMPLICATIONS To identify possible occult primary lung tumors, thoracic radiography should be performed on cats with clinical signs of long duration, including weight loss, lethargy, and dyspnea.
