Cat Diseases - Lymphosarcoma

Canine lymphoma
  • Lymphoma is a type of cancer that originates in the lymphocyte cells. A type of white blood cell, lymphocytes play an important and integral role in the body's defenses in the immune system.
  • There are two forms of lymphocytes: B and T cells. Lymphoma may involve neoplastic proliferation of T or B, or non-B/non-T type lymphocytes, occurring primarily in the bone marrow, lymph nodes, and visceral organs.
  • Cat with feline immunodeficiency virus (FIV) or feline leukemia virus (FeLV) is more susceptible to Lymphosarcoma.
  • It is the most frequently diagnosed among all types of feline cancer.
  • Cats living in smoking households are twice as likely to acquire lymphosarcoma.

  • There are no preventative measures for this type of cancer.
  • The only resolution in some cases is to provide extra care to improve the quality of life in affected animals.
  • Cats affected with FIV or FeLV should be kept indoors away from other cats to keep them safest.
  • It is also important to note that if you smoke, avoid presenting your cat in this situation – smoke outside so that it will not affect your pet.
  • There is no single treatment available to treat lymphomas. The major goal is to improve the quality of life for patients for as long as possible.
  • The treatment choice will depend on the site and form of the tumour, and the availability of the treatment options.
  • Chemotherapy is the best treatment option for lymphoma. Besides this drug therapy and radiation therapy may also be given.
  • In a few cases, if the tumour is limited and easy to access, surgical removal may be possible.
  • Supportive care such as fluids to correct dehydration may be given.
