Cancer in Dogs: Most Common Causes

It’s difficult to comprehend that your canine partner has cancer. Cancer is the leading cause of death for dogs over two years old, and it’s essential to be aware. Knowing the causes of cancer in dogs will make the treatment and the coping process easier.

Several cancer types can affect your dog, and they all grow once it begins to expand. Cancer arises when DNA is broken, which results in uncontrolled cell proliferation, like how cancer affects humans. These malignant tumors occur when cells are abnormally proliferating.

The tumors can be eliminated should they be detected before they have spread to other body regions. However, most cancers go undetected and spread into other body areas, making healing difficult.

How Do Dogs Get Cancer?

Because cancer affects dogs similarly to how it affects humans, there is no definite cause. The exact cause of cancer in dogs is still unknown, but we can do our best to know more about the disease affecting so many animals via research.

Old Age

“Old-time” is a common reason for death, but it might also play a part in cancer development. Although there is no one cause of cancer in dogs, data suggest that the risk of developing cancer increases as the dog ages. While research remains inconclusive, evidence suggests that the immune system’s effectiveness decreases with age.

If a cell splits, the immune system of a weaker person is more likely to produce a mutant cell, resulting in uncontrollable growth. Additionally, there are harmful environmental components connected to cancer. The longer a dog’s life span and the longer they live, the more likely one of these dangerous chemicals could be exposed.

Environmental Elements

At present, it appears that everything can trigger cancer. Every day, a new cancer warning appears on the label of a household item, ranging from cleaning goods and cosmetics appliances. Dogs are domesticated, meaning they live in the same environment and therefore are exposed to the same elements as humans.

Certain carcinogens have direct links with cancer, according to research. If you live with someone smoking cigarettes, the smoke influences your pet. Like smog, air pollution can have the same impact on your pet as it does on us.

In addition, pesticides, herbicides, and insecticides are among the chemicals employed in agriculture and landscaping, containing carcinogens associated with cancer. Asbestos and benzene, benzidine nickel, cadmium, uranium, radon, and vinyl chloride are all regarded as carcinogens that can harm your pet just like they harm humans. Visit a veterinary diagnostic lab to get your dog tested for cancer.


Although all canines are susceptible to cancer, research has revealed an amount of genetics that affects the dog’s likelihood of developing cancer. Certain dogs are more prone than others due to a genetic cause. Of course, age and environmental factors can affect your dog, but if your dog’s genetic lineage has been diagnosed with cancer in the past and it is a risk factor, they will increase the risk.

The disease affects larger breeds of dogs more frequently. Similarly, a dog’s physical traits could affect the likelihood of being diagnosed with cancer. Cancerous cells are more likely to develop in thin or light-colored coats in dogs.

Scientists are hoping to determine the source of cancer and, even more crucially, a proven treatment. Pet owners must try their best at this stage in the research to ensure their pets remain as happy and healthy as possible. Click here to get more details.
