Lymphosarcoma
What is Lymphosarcoma? Lymphosarcoma is a type of cancer that involves the blood and lymphatic system inside a cat. It is also referred to as lymphoma. The lymph system plays an integral role in the body’s immune system against viruses and bacteria and other infectious agents. Lymph tissues are present in the skin, spleen, liver, gastrointestinal tract and lymph nodes. This cancer can be contained within one lymph node or a group of nodes or spread to other parts of the body.
How does my cat get Lymphosarcoma? Lymphosarcoma is primarily associated with the feline leukemia virus (FeLV). FeLV is contagious and is passed between cats by bodily secretions such as saliva, urine, or blood. Not all cats infected with FeLV will also develop lymphoma. In addition, cats with feline immunodeficiency virus (FIV) are also more at risk for developing this form of cancer.
How do I know if my cat has Lymphosarcoma? Initially, you may notice that your cat is not acting like his normal self. His appetite may wane and he may lose weight and not keep his coat groomed. He will act lethargic and may begin coughing and seem to have trouble breathing. He may have bouts of diarrhea or constipation and vomiting. You may detect blood in his urine or stool or his lymph nodes will feel swollen. In addition, you may be able to feel lumps or tumors on the chest or stomach areas when you pet or groom your cat. Any of these signs warrant an appointment with your veterinarian who will perform a complete physical exam and conduct some tests. The list includes a urinalysis, blood chemistry panel and most importantly, a test for FeLV. Radiographs (X-rays) are also part of the diagnosis procedure to spot any suspicious masses. Finally, a biopsy is typically taken and evaluated by a lab to confirm cancer cells.
What can I do about Lymphosarcoma? It depends on the location of the cancer and its stage of development. Other factors include if the cat is also dealing with FeLV or FIV. Chemotherapy ranks as the top treatment option to address lymphosarcoma. Surgery and radiation therapy are other treatment options. During and after treatment, work closely with your veterinarian to monitor your cat’s condition. Follow all your veterinarian’s medication and diet instructions. Be prepared to make regular veterinary visits. The current treatment options aim to slow down the progression of this cancer.
Is there anything I can do to prevent my cat from getting Lymphosarcoma? Recent veterinary studies, including one at Tufts University, confirm that cats living with smokers are twice as likely to develop lymphosarcoma than those who live with non-smokers. Vaccinations for FeLV may also lower your cat's risk of contracting this disease.
Are there certain breeds that get Lymphosarcoma more often? No. Lymphosarcoma can strike any cat of any age, breed, gender or mixed breed. It ranks as the most common form of cancer in cats. Cats are more likely to be afflicted with this disease than dogs.
