    Before selecting a specific tool, it’s crucial to appreciate why a structured diagnostic workflow matters. Tumors in dogs can be benign or malignant, slow-growing or aggressive, localized or metastatic. An organized approach minimizes the risk of misdiagnosis, avoids unnecessary procedures, and enables timely intervention.

    Key steps in the diagnostic workflow:
    • Detailed medical history and physical examination
    • Preliminary screening tests (bloodwork, urinalysis)
    • Imaging studies to localize and assess internal involvement
    • Cytology or biopsy for microscopic evaluation
    • Advanced modalities (molecular assays, PET imaging) as needed

    H3: Importance of Early and Accurate Detection
    Early-stage tumors often respond better to treatment, whether that’s surgical excision, radiation, or chemotherapy. Accurate classification—identifying tumor type, grade, and stage—guides therapeutic choices and provides prognostic insight. Delays or errors can allow microscopic disease to spread, complicating management and reducing survival times.

    H2: Clinical Examination and History Taking
    A thorough physical exam sets the foundation for all dog tumor diagnostic techniques. Pay attention to:

    • Palpable masses: Note size, location, consistency, mobility, and pain on palpation.
    • Lymph nodes: Enlargement may indicate regional spread.
    • Mucous membranes and gums: Oral tumors often present as ulcerated masses or bleeding sites.
    • Skin and subcutaneous tissues: Inspect for nodules or lumps under the fur.

    Effective history taking covers diet, environmental exposures, breed predispositions, prior illnesses, and duration of observed signs. Certain breeds carry higher risks for specific tumors—for example, Boxer dogs and mast cell tumors, or Golden Retrievers and hemangiosarcoma.

    H2: Imaging Modalities in Canine Oncology
