Canine Cancer:
Symptoms and Treatments

Canine cancer is a broad term for the many different types of cancers dogs can inherit. Similar to humans, canine cancer can be centralized, or it can spread through the body and affect multiple bodily systems and functions. Though canine cancers cover a wide variety of ailments and can affect different dogs varying by breed, some symptoms are common.



Swelling, wounds that don’t heal, lumps and bumps, enlarged lymph nodes, lameness or swelling in the bones, and abnormal bleeding are all early indicators of canine cancer symptoms.

Treatment Options:


Treatment options also vary in the differing types of cancer, as well as severity. Primary options can include surgery, radiation therapy, and chemotherapy.



Surgery is often the most common treatment, as it is the first step to treat localized cancers and tumors and is frequently the most effective option available. The goal of surgery in treating canine cancer is to remove all of the cancerous cells. If the cancer is caught early enough that it has not spread, surgery can completely cure canine cancer. If the cancer has spread, and there are tumors inhibiting normal bodily functions, removing these tumors via surgery can also be used to increase the quality of life for dogs.

Radiation Therapy:


Radiation therapy as a cancer treatment works by killing or severely injuring cancerous cells that are then unable to divide and grow. The actual therapy process includes focusing a beam or field of intense energy on a certain area or organ of the body. This therapy is targeted to damage primarily cancer cells, while trying to minimize damage to normal cell growth in surrounding areas. Radiation therapy is administered in small “fractions” over a 3-6 week period, particularly if the radiation is targeting tumors. Side effects can vary depending on the location of the radiation therapy. Sensitive tissues, for example on the head and neck, can react with skin damage after exposure to radiation therapy.



Chemotherapy, or drug therapy, is the most versatile cancer treatment, in that it can be used for a variety of different cancers at varying stages. It can be used to shrink, stop the growth of, or destroy cancer cells without imperative additional damage to the surrounding tissue. Recent advances in chemotherapy, as well as advances in managing chemotherapy side effects such as diarrhea, should be discussed with your veterinarian and canine oncologist to ensure your dog is benefiting from the latest canine cancer science.
