Summary

1. What are the causes of oral cancer in cats?

Infographic on the causes of feline oral cancer: cigarette smoke (ingestion during grooming), certain flea collars (chemical substances) and chronic poor dental hygiene (permanent inflammation).

Although the exact causes of feline oral cancer are multifactorial, veterinary research points to certain environmental factors . Exposure to cigarette smoke (secondhand smoke) is one of the major risks, as cats ingest carcinogenic substances while grooming. The use of certain flea collars and chronic poor dental hygiene are also suspected of increasing the risks.

2. Squamous cell carcinoma (SCC): the most common oral cancer

In cats, approximately 70 to 80% of oral tumors are squamous cell carcinomas (SCC) . This is a particularly aggressive and invasive cancer that attacks the tissues of the gums, tongue, or palate. Unlike other cancers, it rarely metastasizes far, but it rapidly destroys local tissues, making eating difficult and painful for your cat.

3. What are the symptoms of oral cancer?

Early detection is vital. Here are the most common clinical signs of an oral tumor in cats :

  • Halitosis: Persistent and unusual bad breath.
  • Ptyalism: Excessive salivation (often tinged with blood).
  • Dysphagia: Difficulty eating, food falling from the mouth or total refusal to eat.
  • Rapid weight loss due to inability to eat.
  • Facial swelling or jaw deformity.
  • Loose teeth without any prior signs of periodontal disease.

4. Feline oral cancer or simply a dental problem?

It's common for owners to mistake the symptoms of cancer for gingivitis or a dental abscess. If your cat has bad breath or is bleeding, a veterinary examination under sedation is necessary. A dental X-ray and a biopsy of the mass are the only ways to confirm whether it's a malignant tumor or a benign dental condition.

5. What are the prognosis and life expectancy?

Oral carcinoma is a serious condition. Without treatment, life expectancy is unfortunately short, often limited to a few months. However, with early detection and an appropriate support protocol (including pain management and immune support), some cats manage to maintain a decent quality of life for longer. Each case is unique and depends on the location of the tumor.

7. Frequently Asked Questions (FAQ)

Does oral cancer cause suffering in cats?

Yes, oral tumors are painful because they cause constant inflammation and can ulcerate. A cat may show its pain by scratching its mouth with its paws or hesitating over its food despite being hungry.

Can my cat still eat with a mouth tumor?

It is crucial to switch to a very soft or liquid diet (pâté mixed with warm water) to facilitate painless ingestion. Using a raised feeding bowl can also help.

Is oral cancer contagious?

No, cancer is not transmitted to other animals in the house, nor to humans. It is an internal cellular disease.

Can tartar removal prevent this cancer?

Good oral hygiene reduces chronic inflammation, which creates a favorable environment for the development of abnormal cells. While not a guarantee of good oral health, healthy teeth contribute to better overall health.
