What Are the Causes of Lymphoma in Dogs?

Lymphoma is one of the most common forms of cancer seen in dogs. It is most common in middle aged to older dogs, but is capable of striking any dog at any age. Lymphoma strikes the lymphoid system of the dogs, a system which is very important part of the immune system. Lymphoma weakens and destroys the lymphoid system, making a dog more susceptible to illness. Most untreated dogs are given a two-month life span from the time of the diagnosis.

Genetics

Dogs can be genetically predisposed to cancer, like humans. If the dog's family has a history of cancer, it is very likely that they to will eventually develop cancer. Certain breeds have even shown a likelihood towards lymphoma. Washington State University has reported that, "...golden retrievers are considered a breed at increased risk of developing LSA." Though no specific genes or genetic code have been linked to any cancer, it is important to know the history of your dog's family. Lymphoma has been shown to be passed down from generation to generation.

Strong Magnetic Fields

Strong magnetic fields, such as those that surround high energy power lines, have been known to give the humans that live underneath of them cancer. These same magnetic fields have been linked to lymphoma in dogs as well. Try to avoid taking your dog to areas that may have these kind of magnetic fields. It is unknown how quickly lymphoma or other cancers form in dogs. Even minor exposure could cause problems.

Herbicides and Pesticides

Some lawn chemicals have been linked to lymphoma in dogs. The 2,3-d herbicide chemical has been named as an element in causing lymphoma in dogs. This chemical has been banned from use, but was fairly common at one point. If you have used a herbicide or pesticide with this chemical, there is a chance that your dog may be "twice as likely to develop lymphatic cancer" as reported by the "New York Times."

Smoking

Smoking has been tenuously linked to canine lymphoma. Kim Marie Labak of the University of Illinois College of Veterinary Medicine has noted that dogs exposed to second hand smoke are much more likely to develop all forms of cancer. If you have a dog and you smoke, it may save your dog's life to simply step outside every time you have a cigarette.

Age

Middle aged to older dogs are more likely to develop cancer than younger dogs. This is true of all animals and is a hard fact to avoid. The older your pet gets, the more likely they are to develop cancer.
