How Common Is Stomach Cancer in Cats?


First of all, it’s reassuring to know that stomach cancer is rare in cats, and it only makes up less than 1% of diagnosed cases. Any tumor is classified as either malignant (cancerous and can spread) or benign (not cancerous and does not spread). Unfortunately, while stomach cancer is rare, the majority of stomach tumors in cats are malignant and often spread to other areas of the body.


There are different types of malignant tumors that can be found on or around the stomach. In cats, the most common abdominal cancers are lymphomas, leiomyosarcomas, and adenocarcinomas.



What Causes Stomach Cancer in Cats?


The causes of stomach cancer in cats aren’t specific, but are often related to gender, age, and breed. For example, cats that are more often diagnosed with stomach cancer are older cats, male cats, and siamese cats.



What Are The Symptoms of Stomach Cancer in Cats?


The most common symptoms of stomach cancer in cats is a change in eating habits and appetite, and weight loss. You might also notice chronic vomiting or diarrhea that might be bloody too. Often these symptoms don’t happen all at once, but are chronic problems that tend to get worse over time.


So, if your cat has a lump on the side of their stomach, is it stomach cancer? Often, stomach cancer isn’t visible or able to be felt, as it is a cancer that affects the actual organ in the abdomen. But if you’ve noticed an abnormal growth, it could be a different type of abdominal cancer - whether you notice other symptoms or not, be sure to get it checked out by your vet!



Stomach Cancer in Cats: Life Expectancy and Treatment


The life expectancy or outlook of a cat with stomach cancer depends on a lot of factors, such as the type, size, and progression of the tumor. Generally, surgery is often recommended by vets rather than chemotherapy and radiation.
