Cancer in Dogs

Cancer happens when cells grow out of control and invade nearby tissue. This disease can spread to different parts of the body. Just like people, dogs can get different types of cancer. Some cancers are only in one place (like a tumor), while others spread throughout the body.

What Causes Cancer in Dogs?

As a dog owner, you might be wondering what causes cancer in dogs. Well, the truth is that it’s a complex and multi-faceted disease with no single cause. But, we do know that certain factors like genetics and the environment can play a role in a dog’s risk of getting cancer.

Other potential factors that may increase a dog’s risk of developing cancer include exposure to toxic substances, certain medical conditions, and even certain breeds. Despite the many unknowns, it’s important to understand that there are steps you can take to reduce your dog’s risk of getting cancer. To keep your furry best friend healthy, stay informed, and talk to your vet regularly. This way, you’ll be able to help them live a long and happy life.

What Are the General Symptoms of Cancer?

Symptoms of cancer in dogs may include:

• • Lumps or bumps on the body that are new or growing. Though they may not always be cancerous, it’s important to have your vet check them out.
  • Swelling
  • Persistent sores
  • Abnormal discharge from any part of the body
  • Bad breath
  • Listlessness/lethargy
  • Rapid, often unexplained weight loss
  • Sudden lameness
  • If your dog is experiencing black, sticky poop, this could be a sign of ulcers caused by mast cell tumors. It’s important to get your pup checked out by a vet to determine the cause of this symptom.
  • Decreased or loss of appetite
  • Difficulty breathing, urinating, or defecating

How Is Cancer Diagnosed?

To diagnose cancer in dogs, the first step might be to take a small tissue sample using a needle biopsy. If a lump is present, this can help determine if it’s cancerous. Another option is to remove all or part of the lump through surgery so a pathologist can examine it.

Radiographs, ultrasounds, blood evaluation, and other diagnostic tests may also be helpful in determining if cancer is present or if it has spread.

Dog Cancer Types

The most commonly diagnosed cancers in dogs are;

1. 1. Mast Cell Tumors: Mast cell tumors are one of the most common types of skin cancer in dogs. They can appear as lumps or growths on the skin and may vary in size and appearance.
   2. Osteosarcoma: Osteosarcoma is a type of bone cancer that commonly affects large and giant dog breeds. It usually occurs in the long bones and can cause lameness, swelling, and pain.
   3. Lymphoma: Lymphoma is a cancer of the lymphatic system and can affect various organs and tissues. It often presents as swollen lymph nodes, weight loss, loss of appetite, and lethargy.
   4. Hemangiosarcoma: Hemangiosarcoma is a highly aggressive cancer that originates from blood vessel cells. It often impacts the spleen, liver, and heart, leading to internal bleeding and dysfunction of the organs.
   5. Mammary Gland Tumors: Mammary gland tumors are common in female dogs that are not spayed. These tumors can be benign or malignant and are usually detected as lumps or masses in the mammary glands.
   6. Transitional Cell Carcinoma (TCC): TCC is a type of cancer that affects the urinary bladder. It can cause urinary symptoms such as blood in the urine, increased frequency of urination, and difficulty urinating.
   7. Melanoma: Melanoma is a type of skin cancer that can occur in dogs. It typically affects pigmented skin and can appear as dark, irregularly shaped masses or lesions.
   8. Squamous Cell Carcinoma: Squamous cell carcinoma is a type of skin cancer that commonly affects the nose, ears, and other areas with exposed skin. It can cause ulcerations, bleeding, and difficulty in healing.
   9. Brain Tumors: Dogs can also develop brain tumors, which can cause neurological symptoms such as seizures, changes in behavior, disorientation, and loss of coordination.
   10. Leukemia: Leukemia is a cancer of the blood-forming cells and bone marrow. It can result in abnormal white blood cell counts and compromise the immune system.

It’s important to note that this is not an exhaustive list, and there are other types of cancer that can affect dogs. Early detection, regular veterinary check-ups, and prompt medical intervention are crucial for the diagnosis and treatment of cancer in dogs.
