Liver Cancer in Cats: 2025 Vet Insights 🐱🎗️

Hi, I’m Dr Duncan Houston BVSc, feline veterinarian and founder of Ask A Vet. In this updated 2025 guide, we’ll explore liver cancer in cats, its types, diagnostic approaches, treatment options, prognosis, and how tools like Ask A Vet, Woopf, and Purrz can support both in-clinic and at-home care. Let’s journey together toward better feline liver health. 💙

📌 What Is Feline Liver Cancer?

Cats can develop primary liver tumors—most commonly hepatocellular carcinoma (HCC)—or secondary cancers that spread to the liver. On imaging, these tumors may appear as a single large mass, multiple nodules, or diffuse infiltration :contentReference[oaicite:3]{index=3}.

⚠️ Why It’s Serious

Liver tumors are often malignant and may bleed or impair liver function. While some are benign, malignant types require prompt intervention :contentReference[oaicite:4]{index=4}.

👥 Which Cats Are at Risk?

• Usually older cats (≥10 years) :contentReference[oaicite:5]{index=5}.
• No clear breed predisposition for HCC or bile-duct carcinoma :contentReference[oaicite:6]{index=6}.
• Liver inflammation or toxin exposure may increase risk :contentReference[oaicite:7]{index=7}.

🔍 Recognizing Symptoms

Early signs are often vague:

• Weight loss, decreased appetite, lethargy :contentReference[oaicite:8]{index=8}
• Abdominal enlargement or discomfort
• Jaundice, vomiting, diarrhea—especially with bile-duct tumors :contentReference[oaicite:9]{index=9}
• Collapse or pale gums may indicate bleeding mass :contentReference[oaicite:10]{index=10}

🛠️ How It’s Diagnosed

• Physical exam with abdominal palpation
• Blood tests: liver enzymes, bilirubin, clotting profiles :contentReference[oaicite:11]{index=11}
• Imaging:
• Ultrasound is first-line—detects masses, fluid, nodules :contentReference[oaicite:12]{index=12}
• CT/MRI may be used for surgical planning :contentReference[oaicite:13]{index=13}
• Ultrasound-guided needle-core biopsy for definitive diagnosis :contentReference[oaicite:14]{index=14}
• Chest x-rays to screen for metastasis :contentReference[oaicite:15]{index=15}

🩺 Treatment Options

1. Surgical Removal

Resection of a single liver lobe offers the best prognosis. Cats can survive 1.7–2.4 years post-op for HCC :contentReference[oaicite:16]{index=16}.

2. Secondary or Diffuse Disease

Surgery is often not possible. Options include chemotherapy or palliative supportive care :contentReference[oaicite:17]{index=17}.

3. Bile-Duct Tumors

Surgical removal or stenting may slow progression. Prognosis remains guarded :contentReference[oaicite:18]{index=18}.

4. Medical & Palliative Care

• IV fluids, appetite stimulants, pain relief :contentReference[oaicite:19]{index=19}
• Chemo may help if metastasis present :contentReference[oaicite:20]{index=20}
• Palliative care improves comfort when cure isn't possible

🌱 Prognosis & Monitoring

Outcomes depend on tumor type, stage, and treatment:

• Primary HCC: 1–2 years post-resection; some live beyond 6.5 years :contentReference[oaicite:21]{index=21}.
• Bile-duct carcinoma: ~270–868 days post-lobectomy :contentReference[oaicite:22]{index=22}.
• Metastatic cases: poor prognosis, often a few months :contentReference[oaicite:23]{index=23}.

Follow-up imaging and labs every 2–4 months during the first year :contentReference[oaicite:24]{index=24}.

🐾 At-Home & Telehealth Support

• Ask A Vet: 24/7 guidance during recovery, symptom monitoring, and medication support
• Woopf: At-home fluid kits to maintain hydration and comfort
• Purrz: Track appetite, weight, behavior, and symptoms such as vomiting or jaundice

🔬 2025 Veterinary Advances

• AI-enhanced ultrasound for early liver mass detection
• Minimally invasive liver lobectomy in specialized centers :contentReference[oaicite:25]{index=25}
• Liquid biopsies and novel targeted drugs emerging in oncology trials

✅ Vet‑Approved Care Roadmap

1. Note signs: weight loss, jaundice, pain
2. Get blood work + imaging; suspect cancer → biopsy
3. Plan surgery for solitary tumors; refer to specialists
4. Post-op monitoring & supportive care at home
5. In metastatic cases, combine chemo/palliative care
6. Track recovery using Ask A Vet, Woopf, Purrz tools
7. Schedule re-evaluations every 2–4 months, adjust plan as needed
