Diagnosis
Fine needle aspirate (FNA) provides initial cell type identification. Biopsy with histopathology gives definitive diagnosis and grading. Staging includes blood work, chest radiographs, abdominal ultrasound, and sometimes CT scan or bone marrow aspirate. Specific tumor markers may be available depending on cancer type.
Treatment
Treatment depends on cancer type and stage. Options include surgical excision (curative for many localized tumors), chemotherapy (often well-tolerated in pets with fewer side effects than in humans), radiation therapy, immunotherapy, and palliative care. Multimodal protocols combining surgery + chemotherapy provide best outcomes for aggressive cancers.
Prevention
Spaying before first heat cycle reduces mammary cancer risk by 99%. Regular veterinary exams enable early detection. Monthly home checks for lumps, bumps, and changes. Minimize environmental carcinogen exposure. Some cancer predispositions are genetic — research your breed's risks.
When to See a Vet
See your vet within 1-2 weeks for any new lump, unexplained weight loss, or persistent appetite changes. Many cancers are curable when caught early. Do not take a "wait and see" approach with lumps.
