Aggressive fibromatosis, also known as feline desmoid tumors, is a rare but serious condition in cats characterized by the growth of non-metastasizing fibrous tissue tumors. These tumors, although benign in terms of metastasis, can be locally invasive and cause significant health issues by affecting surrounding tissues and organs. Understanding this condition is crucial for early detection, effective treatment, and ensuring a better quality of life for affected cats. (Source)
How It Is Spread
Aggressive fibromatosis is not an infectious disease, meaning it does not spread from one cat to another. It is a condition that arises due to abnormal cellular behavior in the cat’s body. Unlike viral or bacterial infections, there is no risk of transmission through contact, bodily fluids, or other common modes of disease spread.
Transmission
Since aggressive fibromatosis is not caused by an infectious agent, there is no transmission between cats or from cats to other animals or humans. The condition is thought to develop due to genetic mutations or abnormal cellular activity that causes the excessive growth of fibrous tissue. There is no evidence to suggest that it can be passed on through any form of contact or proximity. (Source)
Symptoms
The symptoms of aggressive fibromatosis can vary depending on the location and size of the tumor. Common symptoms include:
- Visible Lump or Mass: A noticeable lump under the skin, which may grow over time.
- Pain or Discomfort: The cat may exhibit signs of pain, especially if the tumor is pressing on nerves or other sensitive areas.
- Lameness or Difficulty Moving: If the tumor is located near a joint or muscle, it can restrict movement or cause lameness.
- Loss of Appetite: Cats with discomfort or pain may eat less, leading to weight loss.
- Behavioral Changes: Affected cats may become more irritable or less active due to discomfort. (Source)
How It Is Caused
The exact cause of aggressive fibromatosis in cats is not well understood, but it is believed to be related to genetic mutations that cause the abnormal growth of fibrous tissue. Factors that may contribute to the development of the condition include:
- Genetics: Some cats may be genetically predisposed to developing fibrous tissue tumors.
- Previous Injuries or Surgery: In some cases, fibromatosis may develop at the site of a previous injury or surgical scar, though this is not common.
- Cellular Abnormalities: Abnormal cell signaling or mutations in specific genes that regulate cell growth can lead to the development of fibromatosis. (Source)
Who Is Vulnerable
Aggressive fibromatosis can affect cats of any age, breed, or gender, but it is more commonly seen in middle-aged to older cats. There is no specific breed predisposition, though some cases may have a genetic component. Cats that have previously undergone surgery or sustained injuries may also be at a slightly higher risk if abnormal healing processes trigger tumor development.
Problems It Can Cause
Although aggressive fibromatosis tumors do not metastasize (spread to other parts of the body), they can cause significant problems due to their local invasiveness. The issues that can arise include:
- Compression of Organs: If the tumor grows near vital organs, it can compress them, leading to functional impairment.
- Pain and Discomfort: As the tumor enlarges, it may press on nerves, causing pain or discomfort.
- Restricted Mobility: Tumors near joints or muscles can restrict movement, leading to lameness or difficulty in walking.
- Difficulty Breathing: In rare cases, if the tumor is located near the chest, it may affect the cat’s ability to breathe properly. (Source)
Treatment
The primary treatment for aggressive fibromatosis is surgical removal of the tumor. However, because these tumors can be locally invasive and have a high recurrence rate, surgery may need to be followed by additional treatments:
- Surgery: Complete surgical excision with wide margins is the preferred treatment. The goal is to remove all of the tumor tissue to prevent recurrence.
- Radiation Therapy: If the tumor cannot be completely removed or if it recurs, radiation therapy may be used to target remaining tumor cells.
- Chemotherapy: In some cases, chemotherapy may be considered, especially if the tumor is inoperable or recurs after surgery.
- Targeted Therapy: Emerging treatments may involve targeted therapies that focus on specific pathways involved in tumor growth. (Source)
Vaccine
There is currently no vaccine available for aggressive fibromatosis in cats. Since this is not an infectious disease, vaccination is not applicable as a preventive measure.
Prevention
Preventing aggressive fibromatosis is challenging because the exact causes are not fully understood. However, steps can be taken to monitor your cat’s health and catch any potential issues early:
- Regular Veterinary Check-Ups: Routine check-ups can help detect any unusual lumps or masses early, allowing for prompt treatment.
- Monitoring Post-Surgery Healing: If your cat has undergone surgery, monitor the healing site for any unusual growths or lumps.
- Healthy Diet and Lifestyle: Ensuring your cat has a balanced diet and a healthy lifestyle can support overall well-being and potentially reduce the risk of abnormal tissue growth. (Source)
Home Remedies
There are no home remedies that can cure aggressive fibromatosis. However, supportive care at home can help manage symptoms and improve your cat’s comfort:
- Pain Management: Consult your veterinarian for appropriate pain management options if your cat is experiencing discomfort.
- Comfortable Living Environment: Provide a stress-free and comfortable environment for your cat, with easy access to food, water, and a litter box.
- Nutritional Support: Ensure your cat receives a balanced diet to support overall health during treatment. (Source)
How Humans Can Protect Their Cats
To protect your cat from the complications of aggressive fibromatosis, consider the following:
- Early Detection: Regularly check your cat for any lumps or unusual growths and seek veterinary advice if you notice anything unusual.
- Prompt Treatment: If a tumor is detected, pursue treatment options immediately to prevent further complications.
- Regular Vet Visits: Maintain a schedule of regular veterinary visits to monitor your cat’s health and catch any potential issues early. (Source)
Cure
While surgical removal of the tumor is the most effective treatment, the condition can recur. Therefore, ongoing monitoring and follow-up care are crucial. There is no guaranteed cure for aggressive fibromatosis, but with proper treatment and care, many cats can continue to live comfortable lives.

Global Organizations and Expert Opinions
Global organizations such as the American Veterinary Medical Association (AVMA) and International Cat Care emphasize the importance of early detection and treatment of tumors in cats. Veterinary oncologists and researchers are continuously exploring better treatment options, including surgical techniques, radiation therapy, and targeted treatments to improve outcomes for cats with aggressive fibromatosis.
Conclusion
Aggressive fibromatosis is a challenging condition that requires prompt attention and appropriate treatment to manage effectively. While it is not curable in all cases, early detection, surgery, and supportive care can significantly improve the quality of life for affected cats. Regular veterinary care and vigilance on the part of cat owners are key to ensuring the best possible outcomes.
