Kidney tumors can cause abdominal pain, blood in the urine, or non-specific signs such as nausea or vomiting, weight loss, lethargy, or abdominal distension. Some animals may also have abnormalities on routine bloodwork, particularly their complete blood count.
However, the average survival time for dogs diagnosed with renal carcinoma is 8 to 16 months after diagnosis.
Symptoms And Signs Of Cancer In Dogs
Lumps and bumps underneath a dog's skin. Abnormal odors emanating from the mouth, ears, or any other part of the body. Abnormal discharge from the eyes, mouth, ears, or rectum. Abdominal swelling.
Tumors in the mouth, nose, or anus can lead to offensive smells. Lack of interest in exercise and play, or a decrease in stamina. This can be your dog slowing down from old age, but it can also be one of the first signs of illness. Mobility issues like limping or stiffness.
However, it is important to understand that any tumor type can be associated with pain. Pain can be due to invasion and destruction of surrounding tissues, including nerves and bones. It can also result from regional or distant metastasis to sites such as bone, the body cavity (serosal surfaces), or the meninges.
Papillary renal adenoma is the most common non-cancerous kidney tumour. These tumours are small, grow slowly and usually don't cause any symptoms. They are often found during an imaging test done for other reasons.
A kidney mass, or tumor, is an abnormal growth in the kidney. Some kidney masses are benign (not cancerous) and some are malignant (cancerous). One in four kidney masses are benign. Smaller masses are more likely to be benign.
How fast kidney cancer spreads is widely variable. Some studies suggest an average growth rates of 0.3 centimeters (cm) per year, but findings vary widely. The grade of the cancer, the person's age and other factors can play a role . Kidney cancers are tumors that start growing inside the kidney.
The average growth rate in most studies has been observed at 0.3 cm/year. When large tumors were followed, the growth rate was slightly higher (0.44–0.57 cm/year) (Mues et al.
Cost of Nephrectomy in Dogs
The cost of nephrectomy can range from $900-$1,500. The cost of the procedure and related treatment varies, depending on the clinic and severity/complexity of the condition being treated.
How long can my dog live with cancer after treatment? There again, it depends on the individual case. It depends on how aggressive or advanced the particular cancer is. By the time it's detected, some dogs will live weeks to months, while others will live for years.
Types of Kidney Tumors in Dogs
Carcinoma (forms in the lining and is the most common type)
Kidney cancer usually doesn't have signs or symptoms in its early stages. In time, signs and symptoms may develop, including: Blood in your urine, which may appear pink, red or cola colored. Pain in your back or side that doesn't go away.
"Small" Kidney Tumor (<4cm)
Not all growths on the kidney are cancer! It is important not to confuse a potential kidney cancer with a kidney cyst or other benign lesion. Cysts are fluid filled structures that range from being "simple cysts" which are benign to more complex cysts which could be cancerous.
Partial nephrectomy (nephron-sparing surgery)
In a partial nephrectomy, the surgeon removes only the part of the kidney that contains cancer, leaving the rest of the kidney behind. As with a radical nephrectomy, the surgeon can make the incision in several places, depending on factors like the location of the tumor.
Types of benign kidney tumors include:
Renal adenoma – Renal adenomas are the most common form of benign, solid kidney tumor, and are typically small, low-grade growths. Their cause is unknown. Renal oncocytoma – Oncocytoma is a benign, usually asymptomatic tumor that can grow quite large.
Some renal masses are benign (not cancerous) and some are malignant (cancerous). One in four renal masses are benign. Smaller masses are more likely to be benign. Larger masses are more likely to be cancerous.
The vet may also palpate your dog to feel for any bumps or lumps. By performing tests and a thorough physical exams, your vet will be able to determine whether your dog has cancer, then recommend best treatment options.
Age is not a disease, and your dog is never “too old” to receive the quality care he or she needs, even if it requires anesthesia and surgery. Let's discuss how to reduce the risks of surgery for your senior dog and why quality care at every age is critical.
Difficulty walking: Limping or refusing to use some limbs could potentially indicate a bone tumor. Extreme fatigue: Your normally active dog or cat may seem depressed and take no interest in exercise or play. It's also common for a pet with cancer to sleep several more hours per day than usual.
