What are the symptoms of cancer in cats?

The last thing you want is for your cat to be affected with any type of cancer. Cats can have many of the same cancers and symptoms as dogs although there are some differences. You can help your cat with a better prognosis if you know the signs and symptoms of cancer. The disease is described as uncontrolled cells in the body that spreads to invade other cells and tissues. Older cats over the age of 10 are prone to cancer which is a difficult disease to avoid. The most common cancers, signs and symptoms in cats are – 

Skin tumors are not most common in cats and if one is detected, they are most often malignant. You should examine your cat’s body often as tumors will be evident with a lump or mass on the skin – anywhere on the body.
Abdominal tumors are complicated to detect, just as they are in dogs and the best you can do is note any unusual signs and symptoms such as weight loss, a change in eating habits, protracted vomiting, constant diarrheal issues and an enlargement of the abdomen.
Mammary gland tumors are common in older female cats, especially one that has not been spayed. Over 85 per cent of mammary gland tumors are malignant and this type of cancer is the third most common cancer disease in cats. The most common types of cancers affecting a cat are skin tumors and lymphoma. The most common symptom of this cancer type is a lump in the breast tissue.
Lymphoma in cats is most often associated with the feline leukemia virus and can affect the digestive system. Normal symptoms are vomiting, lethargy and diarrhea. At least 25 per cent of cats with the feline leukemia virus are prone to lymphoma.
