Stomach cancer is painful and affects the muscles in your cat's stomach. Our Upland vets will describe signs of stomach cancer in cats, as well as diagnosis and treatment options.
What Is Stomach Cancer?
This relatively rare but painful cancer can impact the muscles in the stomach in cats.
Typically, the disease only appears in cats over six years of age, but may be diagnosed in cats of any breed. Stomach cancer or Leiomyosarcoma is an aggressive stomach and intestinal cancer with a high tendency to metastasize (spread) to other parts of the digestive tract, or other vital organs.
What Causes Stomach Cancer In Cats?
To establish what causes leiomyosarcoma in cats, more research needs to be conducted. Currently, we’re not sure of the cause of this stomach and intestinal cancer.
What Are Symptoms Of Stomach Cancer In Cats?
It can be somewhat difficult to diagnose stomach cancer in cats, as our four-legged friends will often not display any obvious signs of the disease until it’s advanced to its later stages. When it has advanced, symptoms start to appear gradually - over weeks or months.
Signs of the stomach and intestinal cancer in cats can also often mimic symptoms of other less serious gastrointestinal conditions.
If your cat has leiomyosarcoma, you may see one or more of these symptoms:
- Reduced appetite
- Gas
- Weight loss
- Lethargy
- Stomach growling
- Blood in stool
- Black stool
- Chronic intermittent vomiting
- Diarrhea
How Is Stomach Cancer Diagnosed?
If your cat is displaying symptoms of leiomyosarcoma or other gastrointestinal issues, your vet will feel your cat’s stomach and intestines to find out if he or she is exhibiting any signs of growth, enlarged lymph nodes, or pain. If the veterinarian suspects stomach cancer, diagnostic testing will be recommended.
Tests that may help to diagnose stomach cancer in cats include:
- Urinalysis
- Endoscopy
- Ultrasound-guided biopsy
- X-rays
- MRI or CT scans
- Blood tests
What pain management options are there for cats diagnosed with leiomyosarcoma? With many forms of cancer (and some cancer treatments), your pet may unfortunately experience pain.
Pain caused by cancer may significantly reduce your cat’s quality of life, which is why your vet may take a proactive approach to manage pain if your cat is diagnosed with stomach cancer.
Rather than wait for signs of pain to appear, your vet may be able to prescribe medications to help prevent it before it starts, helping your cat to live a more comfortable life.
How Is Stomach Cancer In Cats Treated?
Your vet may be able to perform surgery to remove the tumor and some of the surrounding tissue. However, keep in mind that the effectiveness of surgical treatment will depend on whether cancer has spread to other parts of the body.
After your cat is initially diagnosed with stomach or intestinal cancer, further diagnostic testing may be required to help your vet establish the extent of your cat’s condition, along with the best treatment options.
