Diagnosis of canine tumours: 1. Biopsy. Biopsy is a rapid and accurate clinical diagnosis, usually made by cutting, puncturing, scraping or microscopically examining the tumour tissue with pieces of tissue that have been shed. Before biopsy, basic information about the dog should be known, such as breed, sex, age, tumour growth site, growth rate, appearance and palpation. 2. Instrumental diagnosis. Using X-ray fluoroscopy and taking pictures is an effective method to determine the site of tumour. For abdominal tumours, ultrasound can be used to assist in the diagnosis. CT tumour diagnosis is more accurate, but because of the high cost of the equipment, not many of them are available in domestic veterinary clinics. 3. Immunopathological examination. The diagnosis is made by examining the antigens and antibodies associated with the tumour. 4. Histochemical examination. Used to identify tumours that resemble normal tissue structure and morphology.
