Lymphoma Symptoms in Cats? Lymphoma Diagnosis? Treatment and Types of Lymphoma


Lymphoma is a common type of cancer in cats. Lymphoma occurs as a result of the uncontrolled growth of immune cells called lymphocytes. In cats, lymphoma can occur in the lymph nodes, liver, spleen, bone marrow, and other organs. The exact cause of lymphoma is not known, but some factors are thought to play a role.

Lymphoma symptoms in cats can be general cancer symptoms such as swollen lymph nodes, loss of appetite, weight loss, vomiting, diarrhea, lethargy (insomnia), difficulty breathing. Symptoms may vary depending on which part of the body the lymphoma is in.

The diagnosis of lymphoma can be made by the veterinarian through physical examination, blood tests, biopsy and imaging studies. Definitive diagnosis is obtained by an examination at the cellular level.

Treatment for lymphoma may vary, depending on the veterinarian's condition of the patient's condition and the extent of its spread. Treatment options may include chemotherapy, radiotherapy, surgery, and supportive treatments. However, treating lymphoma in cats can be challenging and treatment outcomes often vary.

Early diagnosis is important in the fight against lymphoma. If you are seeing signs of lymphoma in your cat, it is important to consult a veterinarian. The veterinarian will take the necessary steps to determine the appropriate diagnosis and treatment plan.

Types of Lymphoma in Cats

Lymphoma in cats is a type of cancer that can be divided into different subtypes. The most common types of lymphoma are:

  • Multicentric Lymphoma: It is the most common type of lymphoma in cats. It causes abnormal enlargement of lymph nodes (in the neck, armpits, groin). Significant swelling and enlargement of the lymph nodes can be observed. This type of lymphoma usually causes lymphoma cells to spread to surrounding organs.

  • Alimentary (Gastrointestinal) Lymphoma: This type of lymphoma can occur in various parts of the digestive tract in cats. It can affect organs such as the stomach, intestines, and pancreas. Gastrointestinal symptoms such as vomiting, diarrhea, loss of appetite, weight loss and abdominal pain may be observed.

  • Mediastinal Lymphoma: Mediastinal lymphoma is a type that affects the lymph nodes in the middle of the chest cavity, called the mediastinum, in cats. This type of lymphoma usually occurs in young cats. Respiratory system symptoms such as difficulty in breathing, coughing, wheezing may be observed.

  • Extranodal Lymphoma: This type of lymphoma occurs in organs other than the lymph nodes. For example, organs such as the skin, eyes, nose, kidneys, central nervous system may be affected. Symptoms may vary depending on the organ affected.

These are just a few examples of types of lymphoma. Lymphoma is a complex cancer that can be divided into different subtypes. Your veterinarian will perform the necessary tests to determine the type of lymphoma and create the appropriate treatment plan.

Diagnosis of Lymphoma in Cats

The diagnosis of lymphoma in cats is made by the veterinarian using various methods. Below are some commonly used methods and tests for diagnosing lymphoma in cats:

  • Physical Examination: The veterinarian will perform a physical exam to assess your cat's overall health. He or she will check for swelling or abnormalities in the lymph nodes.

  • Blood Tests: Blood tests can be used to assess the cat's general health and rule out other diseases. Blood tests may include special tests such as complete blood count, biochemistry panel, and lymphoma markers.

  • Imaging Methods: Imaging methods such as X-ray, ultrasound or computed tomography (CT) can be used to visualize your cat's internal organs and lymph nodes. These tests can help identify lymphoma spread and affected areas.

  • Biopsy: One of the most important steps in diagnosis is to perform a biopsy, which allows lymphoma cells to be examined under a microscope. The veterinarian may biopsy a sample of the swollen lymph node or affected organs. A biopsy can be done by needle aspiration or a surgical procedure.

  • Cytology and Histopathology: Biopsy samples are sent to the laboratory for cytology and histopathology tests. Cytology confirms the presence of lymphoma cells by examining the cells under a microscope, while histopathology determines the type and grade of lymphoma by examining tissue samples.

The combination of these tests and the veterinarian's evaluation is used to diagnose lymphoma in cats. Once a definitive diagnosis is made, the veterinarian will evaluate the patient's condition to determine appropriate treatment options.
