Horses with many white markings are somewhat more frequently affected by this type of cancer. It occurs particularly frequently in the eye area and on the reproductive organs.
Various types of tumours can occur in the nasal and sinus cavities of horses. However, the animals often only show symptoms at later stages. A combination of radiation therapy and previous surgery is usually suitable as treatment.
As the name suggests, this type of cancer mainly affects grey horses. The growths often form under the tail root or on the anus, sometimes on the eyes, in the glands and in the genital area. Organs can also be affected. Black skin cancer normally grows slowly, but several tumours often occur simultaneously.
This tumour affects the connective tissue of different localizations. It is malignant and can spread throughout the body via the bloodstream or lymphatic system.
Horses of all ages and breeds suffer from this tumour. The trigger is an infection with papillomaviruses. Equine sarcoid hardly ever spreads, so it rarely forms metastases. This is good for the prognosis. However, the tumour often returns if solely an operation has been carried out.
