Tumors in cats
When to visit the vet?
Non-urgent see a veterinarian within 2–3 days
ORANGE for rapid growth, ulceration/bleeding, pain, fever/apathy, lymph node enlargement, or if the tumor location impairs function/airways. RED for heavy bleeding, airway obstruction, or signs of shock.

Definition
Can Occur with the Following Diseases:
Basics and possible causes
Tumors usually develop through uncontrolled cell division. The exact causes of these cell growths are not always clear, but there are several factors that can contribute to them. The most common include genetic predispositions, environmental factors, and the cat’s age.
Genetic factors play a significant role in the development of tumors. Certain cat breeds have a higher susceptibility to specific types of cancer, which is due to hereditary genetic mutations. These mutations can interfere with the normal function of genes that regulate cell growth and division.
Environmental factors such as exposure to chemical pollutants, smoke, ultraviolet radiation, or certain viruses can also increase the risk of developing tumors. In cats, the feline leukemia virus (FeLV) is known to increase the risk of cancer.
Age is another significant factor, as tumors occur more frequently in older cats. As cats age, the likelihood of accumulating genetic mutations increases, which can raise the risk of uncontrolled cell division.
Typical accompanying symptoms
-
Weight loss: Unintentional weight loss can be a sign of a tumor, as the cat’s metabolism changes and it may have less of an appetite.
-
Loss of appetite: Cats with tumors may lose interest in food, leading to a lack of appetite.
-
Lethargy: A general feeling of tiredness or weakness can occur in cats with tumors as their body is weakened by the disease.
-
Changes in behavior: Behavioral changes such as increased hiding, restlessness, or aggressiveness can indicate discomfort or pain.
-
Swelling or lumps: Visible or palpable swelling on the skin or inside the body can indicate the presence of a tumor.
-
Vomiting or diarrhea: These symptoms can occur if the tumor affects the digestive tract.
-
Difficulty breathing: Tumors in the lungs or chest can impair breathing.
When to visit the vet?
A veterinarian should be consulted immediately if the cat exhibits any of the above symptoms and they do not improve within a few days. Particular warning signs are sudden weight loss, palpable lumps or swelling, and behavioral changes.
For acute symptoms such as shortness of breath, persistent vomiting, or diarrhea that can lead to dehydration, an immediate visit to the vet is essential. These symptoms can indicate an advanced illness that requires immediate medical help.
Even if the symptoms appear less acute, it is important to have a veterinary examination if a tumor is suspected. Early diagnosis can significantly improve the prognosis.
Symptom recognition for animal owners and veterinary diagnostic procedures
It is important for the pet owner to watch for unusual changes in the cat’s behavior or health status. Regular observations at home, such as feeling the body for swelling and monitoring appetite and activity levels, can be helpful in recognizing early signs.
The veterinarian will usually perform a thorough physical examination to identify possible tumors. This may include palpating the entire body as well as examining the eyes, ears, mouth, and skin. If a tumor is suspected, further diagnostic procedures are often used.
Diagnostic procedures include imaging techniques such as X-rays, ultrasound, or computed tomography (CT) to determine the location and size of the tumor. A biopsy, where a tissue sample is taken, may be necessary to confirm the type of tumor and determine whether it is benign or malignant.
Additionally, blood tests can be performed to get general information about the cat’s health and determine if the tumor is affecting other organs.
What can pet owners do and professional therapy options
It is important for the pet owner to keep the cat in a stress-free and comfortable environment. This can help improve the cat’s overall well-being and reduce stress that could worsen symptoms.
A balanced diet tailored to the cat’s specific needs can also help provide relief. The veterinarian can make dietary suggestions that support the cat’s nutritional status and stimulate the appetite.
Administering medications as prescribed by the veterinarian is crucial. Painkillers or anti-inflammatory medications can help relieve discomfort and improve the cat’s quality of life.
Regular check-ups with the veterinarian are also important to monitor the course of the disease and adjust the therapy accordingly. This allows for early detection of changes and a quick response to new symptoms.
Outlook on current research
Research into tumors in cats has made significant progress in recent years. Scientists are focusing on the genetic and molecular basis of tumors to better understand how they arise and develop. These findings are crucial for developing targeted therapies that can not only stop the growth of tumors but also prevent their return. In particular, much emphasis is placed on researching gene mutations that lead to an increased probability of cats developing tumors. Through genetic testing, potentially affected cats can be identified early and monitored accordingly.
Another focus of research is the development of new diagnostic methods. Traditionally, tumors in cats were diagnosed through physical examinations and biopsies. However, modern research is working on less invasive methods such as liquid biopsy, which makes it possible to identify tumor markers in the blood. This technique could allow veterinarians to detect tumors earlier and begin treatment before they are advanced.
Therapy approaches for tumors in cats are also being continuously refined. Immunotherapy, which stimulates the cat’s immune system to fight tumor cells, is showing promising results. Researchers are also investigating the combination of chemotherapy and targeted drugs to increase treatment effectiveness and reduce side effects. In addition, there are ongoing studies on the use of radiation therapy with high-precision techniques aimed at destroying tumor cells while sparing healthy tissue.
Against the backdrop of increasing life expectancy in cats, the importance of prevention strategies in research has also grown. Studies are examining how dietary habits, environmental factors, and lifestyle can influence the risk of tumors. The goal is to provide cat owners with recommendations on how to minimize the tumor risk for their animals. The study of antioxidants and other dietary supplements that strengthen the immune system and reduce inflammatory conditions is also an active area of research.
