Squamous cell carcinomas are always serious and require prompt veterinary treatment. Ultraviolet light exposure is thought to be a frequent trigger for the cancer growth. Horses with light skin of the eyes or genitalia are at risk. They can be very aggressive locally and may harm the function of nearby structures. Some of these tumors look like tiny pink cauliflowers while others are ulcerated pits in the tissue. It is most commonly found on the external genitalia and around the eyes, including the cornea and third eyelid. Squamous cell carcinoma is an invasive tumor that can affect areas of skin, skin mucosa (lining) and sinuses. You should always ask your vet to examine any odd skin region that becomes hairless or turns into a lump. However, certain forms are very aggressive locally and hard to control. Sarcoids have never been reported to spread inside the body. Treatments choices include freezing the tissue (cryotherapy), heating the tissue (laser treatment), injecting or implanting chemotherapy type drugs in the area and/or applying a topical paste that may make the body “reject” the sarcoid cells (Xterra). If your veterinarian decides to operate on a sarcoid, usually another type treatment will be paired with the surgery. Simple removal may result in the mass coming back with a vengeance. However if they are large, or fast growing, or located near the eye or tack sites, they may become a big problem. If they are small (quarter size) and are not located near the eye or a place where the bridle or saddle would rest, they may never bother the horse. No breed, age or sex predilection has been found. They are caused by a virus that is spread by flies. Common sites for growth are on the ear, neck or around the eyelids. They show up in several different forms: some are hairless circles, others are wart like thickened bumps, some are smooth firm lumps and still others are fleshy, ulcerated masses. Fortunately screening for these tumors is easy-you can see them! Horse owners should be on the lookout for three common skin tumors: sarcoids, squamous cell carcinomas and melanomas. Cancers of the inside of the body are rare in horses, but cancers of the skin are fairly common. Many cancers have better survivability the earlier they are caught.Posted at 00:30h in Articles by Kristy TacconeĬancer awareness programs abound in human medicine: virtually everyone gets screened for at least one type such as breast, cervical, colon or prostate cancer. If you see any changes in your horse, whether they are behavioral or physical, you should always seek immediate vet care. The four types of lymphosarcoma are generalized, intestinal, mediastinal, and cutaneous. Since the lymphatic system is spread throughout the horse’s entire body, this is the most common and generally most aggressive form of cancer. Male horses are prone to prostate cancer, which is becoming more of a problem as more horses are being exposed to abnormal internal and external factors. Testicular tumors are known in stallions but are not very common and are usually benign. When it does occur, it’s usually malignant and has a poor prognosis for long term survival. #4 - Reproductive system cancersīreast cancer (mammary neoplasia) is not very common in mares. They can be removed with surgery or treated with chemotherapy, though they are known to return if not all of the affected tissue is removed. Even if they become huge, they usually stay in their local area without affecting other parts of the body. One of the most common skin tumors found on horses, sarcoids usually don’t spread internally. This type of cancer is treatable if caught early enough. Sunny regions produce even higher numbers of tumors around the eyes. Horses with white faces are especially prone. This is especially true in places with little hair covering, such as around the eyes, mouth, anus, or genitalia. This type of skin cancer in most common in areas of unpigmented skin. Appearing any time after the age of 4 or 5, growths that appear on younger horses are more likely to become malignant more quickly. Occurring in any dark-skinned horse, melanoma is most common in gray horses with a large percentage of gray horses over the age of 15 developing melanomas. Are you familiar with the most common types of cancer in horses and what you should be watching for? We've compiled a list of the 5 most common types of cancer in horses. Nobody wants to think about their equine friend getting cancer, but it is something that many horse owners are forced to deal with.
