Does Squamous Cell Carcinoma Skin Cancer Hurt
Some people notice only a change to their skin, such as a sore that wont heal or heals and returns.
This skin cancer can also cause symptoms, such as:
-
Feeling sore or tender where you have the SCC
-
Numbness or a pins-and-needles sensation
Any sore, wart, or growth that isnt healing or heals and returns should be examined by a board-certified dermatologist.
Causes And Risk Factors Of Skin Cancer In Dogs
Just like in people, all of the causes of skin cancer in dogs are not completely understood but there are some specific things scientists know contribute to the likelihood of a dog developing it.
- Sun Exposure: Areas of skin that are not protected by thick fur are more likely to be develop some types of skin cancer, especially if that skin is a light color These areas may be completely hairless or just have a short or thin layer of fur.
- Specific Dog Breeds: Vizslas, all sizes of Schnauzers, Doberman Pinschers, Airedale Terriers, Bay Retrievers, Scottish Terriers, Keeshonds, Labrador Retrievers, Bassett Hounds, Collies, Dalmatians, Bull Terriers, Beagles, Boxers, Pugs, and Boston Terriers may all be more likely to develop different types of skin cancers than some other breeds.
- Black Dogs: Dogs of this fur color seem to be more likely to develop malignant melanomas.
- Adult and Senior Dogs: As dogs mature, they develop cancer at higher rates than younger dogs.
- Excessive Licking or Chewing: Because chronic inflammation can increase cancer risk, excessive licking or chewing at one area of skin may lead to cancer.
Recovery And Management Of Skin Cancer In Dogs
Recovery and management of skin cancer is highly dependent on the type of tumor present. Your veterinarian will review any diagnostic findings and discuss your pet’s recommended treatment and prognosis. They may choose to refer you to a veterinary oncologist.
After surgery, your dog may feel sore and your veterinarian will likely prescribe pain medication. Please strictly follow all medication directions. Many patients will need crate rest. Your veterinarian will give you a time frame for return to normal activity levels.
If chemotherapy is part of your pets treatment plan, it can cause nausea, vomiting, diarrhea and low energy levels. Your vet may prescribe anti-nausea medications, or other supportive therapies, while your pet is undergoing chemotherapy. It is also important to ensure that your pet is getting high-quality food to aid in a quick recovery.

Experimental Diagnostic And Therapeutic Considerations
Experimental models in the study of melanic tumors
The finding of an experimental animal model, even the ideal animal in a welldefined experimental scheme, is essential for cancer research.
In order to clarify some essential problems that might explain thedevelopment of melanoma in man, it is necessary to find some experimentalschemes in animals or cell cultures. The unanimous acknowledgement that theactivity of phenotypically defined premalignant cutaneous lesions canprogress directly into melanoma in predisposed individuals has led to theinvestigation of possible genetic influences on this progression. There arestill difficulties regarding the establishment of the genetic or molecularbase for the malignant transformation of a benign naevus-like cutaneouslesion, or of a melanocytoma into a melanoma, in humans.
The possibility to isolate and culture human melanocytes in successivegenerations, with the involvement of environmental agents that activate thegenetic components of the transformation, has opened the perspective for theunderstanding and explanation of the complex phenomenon of melanocytemalignization and the appearance and development of melanomas.
The dwarf Sinclair pig, used as an experimental model for the study ofmelanic tumors, has led to some clarifications and has opened perspectivesin the elucidation of some issues regarding the role of the genetic factorand ecological factors in the initiation and development of melanocyticmelanomas.
Diagnosing Skin Cancer In Dogs
Diagnosis of skin cancer often starts with fine-needle aspiration . FNA involves your veterinarian extracting a sample of your dogs tumor cells using a syringe with a small needle. Then, the cells are examined under a microscope.
In some cases, your veterinarian might perform a biopsy as well. A biopsy is more thorough as it examines a larger sample of the tumor mass. A chest x-ray may also be performed to check if cancer has spread to any vital organs.
If necessary, your veterinarian will consult with a veterinary pathologist or refer you to a veterinary oncologist for confirmation of diagnosis and suggested treatment plans.

S Of Squamous Cell Carcinoma On The Skin
The following pictures show many of the ways that SCC can appear on the skin.
Rough-feeling, reddish patch
This is an early sign of squamous cell carcinoma.
Round growth with raised borders
This squamous cell carcinoma developed from a pre-cancerous growth called an actinic keratosis.
A sore that won’t heal or heals and returns
On the skin or lips, squamous cell carcinoma can look like a sore.
Age spot
This can be a sign of squamous cell carcinoma, which is why you want a board-certified dermatologist to examine your skin before you treat any age spot.
Raised, round growth
This is a common sign of squamous cell carcinoma of the skin.
Animal’s horn
When squamous cell carcinoma looks like this, it tends to grow quickly.
In these areas, this skin cancer may look like a:
-
Sore or rough patch
-
Raised, reddish patch
-
Brown or black line beneath a nail
Sore inside your mouth
This squamous cell carcinoma started inside the mouth and grew to cover a larger area.
Dark streak beneath a nail
Squamous cell carcinoma can look like a brown or black line beneath a nail, as shown here.
When it develops around the nail, it can look like a wart that just wont go away. If youve had a wart around a fingernail for years, its time for a dermatologist to examine it.
Disappearing nail
A nail can disappear for many reasons, including an HPV infection, which can cause squamous cell carcinoma.
What Is A Basal Cell Tumor
A basal cell tumor is an abnormal growth or mass resulting from the uncontrolled division of basal cells or cells from the sweat glands, hair follicles, or sebaceous glands. Basal cells make up the bottom layer of the outermost layer of the skin, the epidermis. The basal layer is essentially the defensive layer of the epidermis. It contains many different types of cells, including those involved with inflammation.
Basal cell tumors are one of the most common skin tumors in dogs and cats. A basal cell carcinoma is a type of basal cell tumor that is malignant or cancerous. Fortunately, less than 10% of basal cell tumors are malignant.
“Fortunately, less than 10% of basal cell tumors are malignant.”

Skin Cancer Treatment Options
A diagnosis of cancer for your dog is scary. Many types of skin cancer are treatable if caught early on, but it is understandable to feel worried.
Your dogs prognosis and treatment options will depend on a few factors, including the type of tumor, the location of the tumor, and the stage of the cancer.
Some skin tumors can be removed surgically to great effect. Others may require additional steps, such as radiation or chemotherapy.
Some types of cancer, for example malignant melanomas, are resistant to radiation therapy, while others, such as mast cell tumors, are more sensitive. Your veterinarian may refer you to a veterinarian oncologist when you have a cancer diagnosis. Veterinary oncologists have advanced training in cancer treatment.
Fleas And Ticks On Dog Skin
All dogs are susceptible to fleas and ticks, and while most dogs have no problem with a few fleas, ticks are another story. Ticks and fleas are arthropods, which means they have a hard outer skeleton, called an exoskeleton, that they need to shed in order to grow. They are carnivores and will feed on the blood of their host in order to grow and survive. It is important to remember that not all ticks are the same. There are over 2000 species of ticks on planet earth. There are hundreds of species in the United States alone, and only 10 species are known to actually feed on humans. Ticks and fleas are most commonly associated with dogs. While they can certainly affect other animals, these bloodsuckers prefer to live on canines. The problem is that ticks and fleas not only live on dogs, but they also bite them. Ticks and fleas can cause a variety of illnesses in dogs, all of them very serious. Fortunately, there are a number of ways to protect your pup against these tiny pests. To prevent an infestation, start by treating your dog and his bedding with monthly flea preventative, which can be found at any pet store.

How Do Dogs Get Skin Cancer
The most commonly diagnosed type of tumor in dogs is skin cancer. Because skin cancer is easier to see with the naked eye than some other types of tumors that may need x-rays and diagnostic equipment to identify, and partly because toxins, chemicals and solar radiation in the environment can reach skin more easily than your dogs internal organs.
Fortunately, this also works in yours and your veterinarians favor – as there is a better chance for early detection, which is key to effective treatment, having a number of treatment options and long-term prognosis.
What Causes Basal Cell Tumors
The reason why a particular pet may develop a basal cell tumor, or any tumor or cancer, is not straightforward. Very few tumors and cancers have a single known cause. Most seem to be caused by a complex mix of risk factors, some environmental and some genetic or hereditary. Certain breeds of dogs are more likely to develop basal cell tumors, including Kerry Blue and Wheaten Terriers, Cocker Spaniels, Poodles, Shelties, and Siberian Huskies. Siamese, Persian, and Himalayan cats are most often affected.

What Breeds Of Dogs Get Skin Cancer
Perhaps due to genetic risk factors, some breeds of dogs are more prone to some forms of cancer. Weve already listed some of the breeds that are more likely to develop one type of skin cancer or another.
In general, however, purebred dogs are more likely to develop some type of cancer in their lifetimes . Due to the breeding process, undesirable attributes like being prone to cancer become more likely.
Dogs with light-colored fur or no fur can also be prone to developing malignant melanomas, for example, Bull Terriers. With less fur comes less protection against UV radiation. However, some dogs are at an increased risk even if they have dark fur, such as Schnauzers and Scottish Terriers.

Monitoring Your Dog’s Health
Spotting the signs of skin cancer while the disease is still in the early stages is the key to good treatment outcomes. Familiarizing yourself with all your dogs lumps, bumps, and rashes, during your regular grooming routine, as well as visiting your vet for routine wellness exams can help to catch skin cancers in the early stages.
Whenever you notice an unexplained or unusual lump or bump on your dog, or if you notice swelling around your dog’s toes consult your veterinarian. When it comes to your pet’s health it’s always better to err on the side of caution.
Note:The advice provided in this post is intended for informational purposes and does not constitute medical advice regarding pets. For an accurate diagnosis of your pet’s condition, please make an appointment with your vet.
Preventing Skin Cancer In Dogs
Some types of diseases are preventable, while others are not. As in humans, many cancers are the result of a genetic predisposition. In other cases, cancer is the result of a variety of factors coming together in an unlucky configuration, but there are a few things you can do to lower your dogs risk.
The risk factor most in your control is exposure to sunlight. If you have a light-skinned, short-haired dog breed, limiting your dogs exposure to direct sunlight, especially during the peak daylight hours, may help lower his risk of skin cancer.
The most important thing you can do to help your dog avoid skin cancer, however, is to familiarize yourself with all your dogs lumps, bumps, and rashes, perhaps during your daily grooming routine, and consult your veterinarian if you notice anything suspicious.

What Does Squamous Cell Carcinoma Look Like
Squamous cell skin cancers can vary in appearance, but here, weve provided some examples of how it might appear on your skin.
Squamous cell carcinoma initially appears as a skin-colored or light red nodule, usually with a rough surface. They often resemble warts and sometimes resemble open bruises with raised, crusty edges. The lesions tend to develop slowly and can grow into a large tumor, sometimes with central ulceration.
SCCs can occur on any part of the body, but they are more common on areas of skin exposed to the sun like the scalp, ear or face, so pay attention to these areas.
Squamous cell carcinoma usually develops slowly but can spread to the lymph nodes and other organs if left untreated. If caught early though, it is highly treatable. Early detection strategies are crucial for a successful outcome.
You will notice that all these skin cancer pictures are quite different from one another. Note that not all squamous cell cancers have the same appearance so these photos should serve as a general reference for what they can look like.
Diagnosing Dog Skin Cancer
To diagnose dog skin cancer, your vet will need a sample from the suspicious area. Samples may be taken using fine needle aspiration which takes a small sample of the turmor’s cells to examine, or a biopsy which will allow your vet to take a portion of the tumor’s tissue for examination. Your pup’s tissue samples will then be sent to a lab to be analyzed in order to provide an accurate diagnosis of your dog’s condition.
If skin cancer is confirmed, your vet may recommend additional diagnostic testing to help determine the extent of your dog’s cancer as well as to optimize treatment and provide you with a more accurate prognosis.

What Are The Symptoms Of Skin Cancer In Dogs
The defining sign of skin cancer is a change in the appearance of the skin or a portion of the skin. This change can be a bump, lump, or patch in the affected area. Different types of skin cancer will result in different changes in skin appearance. Some of these include:
- Raised firm wart-like lump for squamous cell carcinoma
- Rubber-like sore for mast cell tumors
- Hairless isolated lumps for histiocytoma
- Dark-pigmented or non-pigmented lumps for melanoma
- Toenail swelling and ulcers for nail bed melanoma
Secondary signs and symptoms of skin cancer include:
- Limping or lameness
- Change in behavior
- Weight gain or loss
While all these signs are great indicators of skin cancer, your veterinarian is the only person qualified to make an accurate diagnosis. Consult with your veterinarian as soon as you notice a change in your dogs appearance and behavior.
Types Of Skin Cancer In Dogs
There are different types of skin cancer in dogs. To simplify things, lets take a closer look at the most common ones.
Fibrosarcoma. This is a malignant form of skin cancer that occurs in the fibroblasts . Fibrosarcoma affects the limbs and surrounding areas and can cause mobility issues.
Fibrosarcoma is more common in middle-aged and older dogs but puppies can also be affected. Large breed dogs like Golden Retrievers, Irish Wolfhounds, and Gordon Setters have a higher risk of getting fibrosarcoma.
Histiocytic Cell Tumors. These tumors start in the histiocytes, a type of immune cell found in different organs, including the skin. They can be benign or malignant. Malignant histiocytic are very aggressive and spread very quickly.
Fortunately, malignant histiocytic sarcomas are rare. There is an increased risk of histiocytic cell tumors in older dogs and in giant breeds like the Bernese Mountain Dog.
Mast Cell Tumors. As the name suggests, mast cell tumors start in the mast cells .
Mast cell tumors are the most common type of skin cancer in dogs, and they can be benign or malignant. Today, there are ways ofshrinking tumors, particularly mast cell tumors.
Mast cell tumors mostly affect Beagles, Labrador Retrievers, Pugs, Boston Terriers, Boxers, Rhodesian Ridgebacks, etc.
Malignant Melanoma. Melanoma is a skin tumor that grows in pigment-producing cells called melanocytes.
Breeds most prone to malignant melanoma include Schnauzers and Scottish Terriers.

How To Treat Dog Tumors At Home
When youre trying to care for a sick dog, life can be pretty tough. Your pet cant do all of the things they are used to doing, as well as not feeling well.
Your vet will probably have some directions. There are also some over-the-counter products that may help. A topical CBD cream can help reduce pain and inflammation, for example.
What may be more important is your attitude and outlook. If youre stressed and unhappy, your dog probably will be too. A more positive outlook can help them be more at ease .
Its also important to be realistic. While dogs can live for years after being treated for cancer, in some cases, you may be buying some extra time to love your pet and say goodbye.
