Cancer Awareness in Pets

Cancer is one of the most prevalent causes of death in dogs and cats. While there are some similarities, cancer in pets is very different from cancer in humans. Many cancers present as a lump or bump. If your pet has a lump or bump, it is best to seek veterinary attention. The veterinarian will examine and aspirate the area. This will help to determine if the mass is malignant or benign. Early diagnosis can greatly increase the chances of a positive outcome for your pet. If your pet is diagnosed with cancer, have hope and do not be discouraged. Although cancer is a dreary word, the options available for treatment in animals may really surprise you. The cost and any side effects of these treatments are usually very manageable. We know it is not just about extending time with your pet; our ultimate goal is the best quality of life for the longest period of time. We will make the best treatment plan for you, your family, and your pet.

Below we have listed some common types of cancer along with related symptoms and treatments.

Lymphoma is most commonly a tumor that develops in the lymph nodes. It can develop in other parts of the body such as the gastrointestinal tract, chest, skin, heart, eyes, central nervous system, and bone. Bloodwork, aspirates, biopsies, radiographs, and ultrasounds can help to diagnose and determine the location. Symptoms of Lymphoma include swollen lymph nodes, vomiting, diarrhea, weight loss, shortness of breath, itchy or red lumps. Some dogs with lymphoma can be treated with chemotherapy. This treatment can greatly extend the length and enhance the quality of their life.

The most common bladder cancer in dogs is transitional cell carcinoma. This is a tumor of the cells that line the urinary bladder. Bladder cancer is not usually detectable by palpation unless the tumor is very large. An ultrasound, urinalysis, and bloodwork are the most common tools for diagnosing bladder cancer. Symptoms of bladder cancer can include straining to urinate, urinating frequently, or blood in the urine. Treatment options are available. Please seek veterinary care if you notice any of these signs.

Osteosarcoma is the most common bone tumor in dogs. This tumor is more likely to affect large breed dogs, but can affect any breed. It can usually be detected by radiographs (x-rays) and biopsies. Most common symptoms of osteosarcoma include pronounced bone swelling and pain or lameness in the affected limb. Treatment options can be discussed with your veterinarian if you notice any of these signs.

Mammary Cancer will usually present as a lump or bump in the mammary tissue. A physical examination, aspirate, or biopsy may be performed to determine if the tumor is malignant or benign. Approximately half of all mammary tumors are malignant. The most common sign of mammary cancer is a solid mass or swollen lump in the mammary glands. When tumors first appear, they may feel like tiny knots just under the skin. They are very hard and can grow quickly. Spaying your pet before their first heat cycle significantly reduces their chances of developing mammary cancer.

Testicular cancer is most common in intact older male dogs but can occur in any intact male dog. A physical examination, biopsy, or bloodwork may be used to detect and diagnosis testicular cancer. Testicular cancer will usually present as a lump or swelling in the testicle, scrotum, inguinal, or abdominal area. This type of cancer can be easily prevented by neutering your pet.

Mast cell tumors account for about 20% of all skin tumors in dogs. Mast Cell Tumors can sometimes appear as small minute growths or lumps but they are still a very serious cancer in dogs. It is important to go ahead and seek veterinary attention. Early diagnosis is the key. An aspirate or biopsy will help the veterinarian determine if the growth is a mast cell tumor. Mast cell tumors can be found on any part of the body and vary widely in appearance. Some tumors can be found on the skin or in the underlying subcutaneous tissue. The tumor may present as one or multiple bumps. These lumps can be smooth, bumpy, or even ulcerated. Treatment options include surgical excision, chemotherapy & even radiation. Please seek veterinary care if you notice any new lumps or bumps on your pet.

Squamous Cell Carcinoma is a cancer that develops in the outer layer of your pet’s skin and is caused by long term exposure to sunlight. Pets with white or light colored hair or skin are at a greater risk of developing this type of cancer. There can also be an increased risk if your pet likes to “Sun” belly up outside. Squamous Cell Carcinomas will usually appear as a sore or growth. The sore may be crusty, bleeding, or take a long time to heal. They will typically not get better with creams or antibiotics. Treatment options can be discussed with your veterinarian depending on the location.
