Nose Cancer (Fibrosarcoma) in Cats
Nasal and Paranasal Sinus Fibrosarcoma in Cats
A fibrosarcoma specifically refers to the abnormal development of cells. It is typically a slow and invasive process that advances before it is discovered. Nasal and paranasal fibrosarcoma is characterized by a malignant tumor based in the connective tissue of the nasal passage or in the surrounding area.
This disease is fairly rare in cats. Typically, by the time the tumor is found, it has metastasized dangerously, but that is not to say that it cannot be treated satisfactorily. Associated factors include age, with most affected cats falling in the range of over six years; and gender, with males, castrated males especially, being more prone to fibrosarcoma than females. With appropriate treatment, cats can have an expected life span of up to 36 months. Without treatment, life span may be limited to five months, depending on the extent of the tumor's invasion.
Symptoms and Types
The abnormal cell development typically begins in one side of the sinus (or nasal passage), but typically moves to the other side as it progresses. There are a variety of signs that can develop, including:
The causes for fibrosarcoma are currently unknown.
There are several other medical conditions that must be ruled out prior to diagnosing fibrosarcoma, including bacterial, viral and fungal infections in the sinuses, hypertension (high blood pressure), parasites, foreign bodies, tooth root abscesses, and facial trauma. Magnetic resonance imaging (MRI) and computed tomography (CT) imaging can be helpful for reviewing the size of the tumor growth and how far it has spread, as well as whether the cells have spread into other parts of the cat's body.
