Symptoms and Treatment of Cancer in Dogs

    Cancer in Dogs

    Cancer in dogs is caused by the uncontrolled growth of abnormal cells in their body. Normally, cells in the body divide and grow in a controlled manner, but cancerous cells divide uncontrollably and can invade nearby tissues and organs. Cancer isn’t always an immediately fatal diagnosis, and many dogs can still live full, rich lives after diagnosis.

    What Causes Cancer in Dogs

    There is no single cause of cancer in dogs, but there are several factors that can increase their risk of developing it. Some common risk factors include:

    • Age – As dogs age, they become more susceptible to developing cancer.
    • Breed – Certain breeds of dogs are more prone to certain types of cancers than others. For example, large breed dogs like Great Danes have a higher risk of developing bone cancer, while certain breeds such as Mini Schnauzers are more likely to develop mast cell tumors.
    • Genetics – Some forms of cancer can be hereditary or passed down through generations.
    • Environmental factors – Exposure to environmental toxins such as pesticides, tobacco smoke and pollution can increase the risk of cancer.
    • Diet – A poor diet that lacks essential nutrients may weaken the immune system and increase the risk of cancer.

    It’s important for dog owners to be aware of these risk factors and take steps to minimise them whenever possible. Regular veterinary check ups can help detect any signs or symptoms early on, which increases chances for successful treatment.

    Signs of Cancer in Dogs

    Spotting the signs of cancer in dogs can be challenging because many symptoms are similar to those of other illnesses. However, there are some common signs that may indicate the presence of cancer, including:

    1. Lumps or bumps: Any new or unusual lumps or swollen areas on your dog’s body should be checked by a veterinarian right away. While not all lumps are cancerous, many forms of cancer present as growths on the skin.
    2. Abnormal odours: Foul smells coming from your dog’s mouth, ears, or any part of their body could be an indication of cancer.
    3. Changes in appetite and weight loss: Cancer can cause a decrease in appetite and unexplained weight loss.
    4. Difficulty breathing: Cancer in the lungs or chest cavity can make breathing difficult for your dog.
    5. Changes in bowel or bladder habits: Diarrhoea, constipation, blood in urine or difficulty urinating can be signs of various types of cancer.
    6. Lameness: Dogs with bone cancer may experience lameness or limping.
    7. Persistent coughing or vomiting: A persistent cough or vomiting that does not resolve with standard treatments could be due to cancer.
    8. Abnormal behaviour: If your dog is lethargic, less active than usual or has trouble getting up and down stairs, it could be a sign that something is wrong.

    Diagnosing Cancer in Dogs

    It’s important to keep an eye on any changes in your dog’s behaviour and overall health and report them to your vet immediately if you notice anything unusual. Early detection is key when it comes to treating cancer in dogs; therefore, regular veterinary check-ups including screening tests like blood work and X-rays can help identify potential issues before they become serious problems.

    Cancer in dogs can be diagnosed through a series of tests and procedures. The first step is usually a physical examination by a veterinarian to check for any lumps or abnormalities on the dog’s body.

    If the vet suspects cancer, they may recommend further tests such as blood work, X-rays, ultrasounds, CT scans or MRIs.

    If a lump or mass is found during the physical exam, the vet may perform a biopsy to determine if it is cancerous. During a biopsy, a small sample of tissue is removed from the lump and sent to a laboratory for analysis.

    In some cases, additional testing may be necessary to determine if the cancer has spread to other areas of the body. Once a diagnosis has been made, treatment options will depend on several factors including the type of cancer and its stage of progression.

    Treatment options may include surgery to remove tumours or chemotherapy/radiation therapy to kill cancer cells.

    Cancer Treatment in Dogs

    The treatment of cancer in dogs depends on the type of cancer, its stage, and the overall health of the dog. Here are some common treatment options for cancer in dogs:

    1. Surgery – Surgery is often the first line of defence against cancer in dogs. The goal of surgery is to remove as much of the tumour as possible. This can involve removing the entire tumour or just a portion of it, depending on its size and location. In some cases, surgery may not be possible if the tumour is too large or has spread to other areas.
    2. Chemotherapy – Chemotherapy uses drugs that kill cancer cells throughout the body. It can be given orally or through an IV, and is typically administered in cycles over several weeks or months. Chemotherapy may cause side effects such as nausea, vomiting, and hair loss, but these are usually temporary.
    3. Radiation therapy – Radiation therapy uses high-energy radiation to kill cancer cells. It can be used alone or in combination with other treatments like surgery or chemotherapy. Radiation therapy is typically administered over several weeks and may cause side effects like skin irritation and fatigue.
    4. Immunotherapy – Immunotherapy involves using drugs that stimulate the immune system to attack cancer cells. These drugs work by blocking proteins that help cancer cells evade detection by the immune system. Immunotherapy may be used alone or in combination with other treatments.
    5. Palliative care – Palliative care focuses on managing symptoms and improving quality of life rather than curing the cancer itself. This may involve pain management, nutrition support and other measures to keep your dog comfortable. While this can be difficult, it is important to ensure that your dog’s last days are full of life and happiness.

    Your veterinarian will work with you to determine the best course of action for your dog based on their specific needs and circumstances. Depending on the type and stage of cancer, multiple treatments may be used together for optimal results.
