Lymphoma in Cats

Common info

Lymphoma is a severe type of cancer that is an effect of the abnormal and uncontrollable growth of lymphocytes. This type of cancer often found in gastrointestinal tracts of the middle- or older-aged cats, or the cats of all genders and ages. The common symptoms found in lymphoma in cats include loss of appetite, vomiting, diarrhea, and weakness, etc.


Lymphoma in cats is an effect of the attack of Feline Immunodeficiency Virus (FIV) and Feline Leukemia Virus (FeLV) infections; an infection in the immune system as well as certain types of medicines application. Apart from these, genetic factors also play an important role in being the cause of the disease, esp. in Siamese, Burmese and Manx cat breeds. Environmental factors, such as cigarette smoke perception, also seem to double the chance of the disease


Lymphocyte or lymph is functions as a fighter against the diseases that enter into the body through the veins in the liver, chest, gastrointestinal tract, nose, spine, and skin. This type of cancer originates from the rapid and uncontrollable replication of the white blood cell lymphocytes that have transformed into cancer cells and spread to several parts of the body, including lymph node, alimentary canal, liver, and lung.
