Feline lymphoma is the most common form of cancer in cats. This extremely malignant feline cancer is found in the lymphatic system, and can cause tumors in cats that spread rapidly throughout a pet's body.
What is Lymphoma in Cats?
Lymphoma, also known as lymphosarcoma in cats, is a cancer of the lymphatic system, a network of lymph nodes and lymphatic vessels which extends over the entire body. Lymphocytes are cells found in the lymphatic system. These cells have many different functions, one of which is to produce antibodies against disease-causing bacteria.
If lymphocytes begin to divide rapidly in an out-of-control fashion, they form a sarcoma, or malignant growth, in the lymph node. Malignant lymphoctyes can break off from the main tumor and travel to new areas in the body via the lymphatic system. This is why lymphosarcoma spreads so rapidly.
Eventually these malignant cells reach the bone marrow. Since the bone marrow produces red blood cells, a severe and fatal anemia is the result.
Which Cats are at Risk for Feline Lymphoma?
This type of cancer used to be seen mainly in younger cats who tested positive for the feline leukemia virus. But since more cats are being vaccinated for feline leukemia, most cases of lymphoma in cats are now seen in animals that are at least nine or ten years old.
The average feline patient is an older male who has a history of stomach and intestinal upsets, like vomiting, and diarrhea. A lack of appetite may lead to weight loss.
Cats who are exposed to secondhand smoke also have a higher incidence of feline cancer, including lymphosarcoma in cats.
What are the Symptoms of Feline Lymphoma?
Every person who's owned by a feline should know the warning signs of cancer in cats. Symptoms of lymphoma in cats include:
- Swollen lymph nodes
- Loss of appetite
- Weight loss
- Vomiting and diarrhea
- Rough hair coat
- Fluid in the lungs
- Breathing problems
- Facial swelling
- Anemia and weakness
- Pale gums due to anemia
How is Feline Lymphoma Treated?
With recent advances in veterinary care, chemotherapy for cats is becoming more common. About 70 percent of cats will respond to treatment, and about a third of these cats may live for two or more years. It's best to ask the vet for a referral to a veterinary oncologist so that the pet can receive the latest treatment.
Surgery may be necessary if a tumor is blocking the bowel.
A cat that is not treated has a life expectancy of four to six weeks.
Can Lymphoma in Cats be Prevented?
It's not possible to prevent feline cancer right now, but keeping a cat away from cigarette smoke and other environmental toxins is always a good idea. A healthy diet and plenty of exercise will keep a feline in good condition, while supporting a strong immune system.
The best way to protect a cat is to know the symptoms of feline lymphoma, and to seek veterinary care immediately if any lumps are found on the pet, or if the pet develops appetite loss and digestive problems.
