Researchers believe that while sun exposure definitely has a big role to play in its development, squamous cell carcinomas often develop due to mutated genes. Squamous cell carcinoma in dogs is also very common. Tumors originating from malignant mast cells are common in Boston Terriers and Pugs. Some dogs with mast cell tumors can also develop stomach ulcers from excessive histamine release. Mast cell tumors release histamine leading to symptoms like itching and sneezing. Mast cell tumor is the most common type of skin cancer in dogs. Mast cell tumors originate from mast cells – cells that are responsible for the release of histamine in allergic reactions. Dog breeds like Miniature and Scottish Terriers are most commonly predisposed to developing malignant melanomas. Malignant melanoma can appear on the lips, mouth, and even nail beds of dogs. They can also present as toe swellings when the cancerous growth involves nail beds. These tumors have a raised, lumpy, often ulcerated appearance. There is often an increased concentration of the pigment melanin in these tumors, which is why they appear dark-colored. Malignant melanomas are caused by an overgrowth in the pigment layer of the epithelium. Some of the most common skin tumors in dogs include: 1. Skin tumor development can start from multiple cell lines, which is why multiple forms of dog skin cancers exist. Some of the most common environmental factors which are linked to an increased risk of malignant tumors in dogs include: in fact, most cancers in dogs develop due to mutations in either the tumor suppressor genes (genes responsible for stopping tumor growth) or the protooncogenes (pro-tumor genes).Įnvironmental factors can also cause malignant tumor growth in canines. Genetic factors play a bigger role in developing cancers in dogs than environmental factors. Genetic factors also play a vital role in the development of skin tumors in canines.Ī brief summary of some of the major causes of skin cancer in dogs is given below. Click here to learn more about other types of cancers in dogs.Įnvironmental factors, albeit important, are not the only cause of skin cancer in dogs. The reason why dogs develop skin cancer more than any other type of cancer may be linked to the fact that their skin is constantly exposed to the environment.
Dogs can get skin cancers just like humans and their diagnosis and treatment isn’t much different as well. Skin Cancer in Dogs: Causes, Types, Symptoms Here is everything you need to know about dog skin cancer, its causes, and also its treatment options. Therefore, it is important for dog owners to be able to pick up the earliest signs of any malignant growth. On the contrary, some of these growths have a tendency to turn malignant (cancerous). It is important to remember that not all types of growths on a dog’s skin are tumors. These growths may include lipomas, which are just benign tumors made up of fat cells, and sebaceous cysts. Rightly so because every dog owner is concerned about their pet’s life, and the word cancer does not exactly bring heaps of comfort and joy either.ĭogs can get all types of growths on their skin. Skin cancer in dogs is the most common type of canine malignancy that dog owners are worried about.
