It’s VERY sad but true! Over 50% of dogs over the age of 10 will die this year from cancer. That’s an astonishing and heart-breaking statistic! And it’s estimated that 33% of cats may die of cancer. Sadly, cancer is one of the most common causes of chronic illness and death in middle-aged to older dogs and cats.
What is causing this shocking statistic? We know that cancer in both humans and animals is an overgrowth of cells that overwhelms the immune system. And any type of cell in our pets’ bodies can begin this uncontrolled growth. This includes cells in any organ of the body - the skin, bones, muscle, liver, lungs, spleen, intestinal tract, and the nervous system. Research shows us that all living creatures have precancerous cells growing all of the time; however, when the immune system is healthy, these precancerous cells are kept in check. However, with stress, or immune system breakdown, the cancerous cells develop into a mass that absorbs vital nutrients, presses against surrounding tissues, resulting in death.
Cancer is one of the most common causes of chronic disease and suffering in pets of all ages. So, what can you do:
A biopsy is an important first step if you suspect your pet may have cancer. It’s important to get a clear diagnosis, since cancer can cause a variety of symptoms that mimic other diseases.
Depending on the specific type of cancer, treatment may include surgery, chemotherapy, or radiation.
Prognosis for pet cancer varies depending on the type of cancer and how early it is diagnosed.
What causes cancer in our pets?
There are many environmental factors that may trigger the genes and cell growth that leads to cancer development. There is increasing awareness of the role that nutrient-poor and processed commercial pet food diets may play in cancer. Toxic preservatives such as ethoxyquin and BHA, food additives, and dyes, as well as questionable by-product ingredients.
Also, environmental exposure to radiation, viruses, lawn chemicals, asbestos, and tobacco smoke have also been linked with certain cancers in dogs and cats.
Also, certain flea and tick pesticides play a big role in triggering cancer in our pets.
Cancer can strike any organ of your pet's body. The following types of cancer are commonly seen in dogs and cats:
Abdominal cancer may involve any of the abdominal organs such as the spleen, liver, kidneys, and intestines. Abdominal cancers can often be hard to recognize early because the abdomen may mask swollen cancerous organs for a long time.
Bladder cancer has been on the rise in dogs with symptoms such as increased urine urgency and frequency, as well as severe bloody urine. Ingredients in many common flea and tick insecticides have been shown to play a large role in pet bladder cancer.
Also, environmental factors such as cigarette smoke have been shown to contribute to this type of cancer.
Bone cancer, or osteosarcoma, is common mainly in large and giant breed dogs and much less common in cats. Research has shown that early spaying and neutering (before one year of age) may predispose susceptible dogs to bone cancer. These tumors may appear on the ribs, pelvis, or leg bones. Bone cancer is one of the more aggressive cancers in dogs. Quality of life may be extended by early limb amputation, along with secondary radiation and possible chemotherapy.
Breast cancer (or mammary gland cancer) is another common cancer in dogs, which typically has a 50% malignancy rate in dogs. In cats, breast cancer is malignant 90% of the time. By spaying female dogs and cats before their second heat, the incidence of breast cancer is dramatically reduced.
Feline leukemia virus (FeLV) and feline immunodeficiency virus may affect up to 5% of cats in some locations. While these viruses commonly cause immune suppression and secondary bacterial and viral infections in affected cats, cancer of the blood cells or bone marrow is seen in many other cats as they get older.
Lymphoma (lymphosarcoma) is one of the most common cancers in pets, and may involve the white blood cells, lymph nodes, spleen, intestines, and bone marrow. While genetic factors play a role in dogs with lymphoma, environmental factors such as overvaccination and nutrient-poor commercial pet foods are also believed to be a risk factors in pets.
Oral cancers can be quite malignant and may spread rapidly to your pet's lymph nodes and the lungs. Pets with mouth cancer may have masses along their jaw and tooth line, as well as bleeding from the mouth, excessive salivation, and difficulty eating.
Prostate cancer is another tumor seen more commonly in neutered dogs. Symptoms of prostate cancer will mimic other urinary tract cancer symptoms, such as increased urgency/frequency of urination, and bloody urination.
Testicular cancer is rare in both dogs and cats, but if detected early, neutering is usually curative, since most forms of testicular cancer tend not to spread to other organs.
NOTE: Middle-aged to older dogs and cats should be taken to your veterinarian at least twice a year for a complete check-up. The earlier a tumor is found, or cancer is diagnosed, the better your pet's prognosis.
