Stomach Tumors (Benign or Malignant) A lump in your cat’s stomach could also indicate a tumor growing from the stomach’s lining or surrounding muscles. These tumors can be either benign (non-cancerous) or malignant (cancerous). Malignant tumors have the potential to spread to other parts of the body.

Tumours/cancer. A swollen belly in cats can be indicative of a tumour or cancer. This is a serious issue and should be treated as a medical emergency. ... The presence of a tumour or cancer in the stomach can cause discomfort or palpable swelling in the abdominal region. Cats might show reluctance when picked up or might adopt a hunched posture.

A 6-year-old, intact female cat presented with sudden collapse. Clinical examinations indicated severe regenerative anemia and a large abdominal mass containing fluid. An exploratory laparotomy revealed a large cystic lesion at the cranial end of the right uterine horn. Ovariohysterectomy was performed, and the cat made a full recovery.

In cats, chemodectomas are reported in the carotid body, 18 in the aortic body, 14,19–26 in the vena cava, 27 in the cauda equina 28 and, recently, in the glomus pulmonale 24 and in the orbita. 29 Metastases occur in approximately 3.3% of carotid body tumours 3 and have been found in the lung, 28 myocardium, pericardium, cranial mediastinal ...

Positron Emission Tomography/Computed Tomography (PET/CT) combines metabolic and anatomical information improving the precision and accuracy of oncological diagnostics. The standardized uptake value (SUV) measures tumor metabolism, yet its accuracy is influenced by the partial volume effect (PVE), impacting small lesion detection. This study aims to refine PVE corrections for small lesions ...
