What are the main cancers in dogs?


Almost half of dogs aged 10 and over are affected by cancer, but a malignant tumor can also sometimes affect a young dog. Any organ can be affected, and it is essential to consult a veterinarian as soon as symptoms appear that may suggest cancer. The earlier the diagnosis, the more likely it is to be cured with appropriate treatment. Let’s take stock of the most common cancers in dogs.

Lung cancer

Its primary form is not very common in canines. However, the lungs of the animal can be the site of metastases carried in these organs by the blood.

Liver cancer

It is a cancerous tumor that produces metastases. Liver cancer is aggressive.

Pancreatic cancer

Pancreatic cancer sets in creepy and can kill the dog in just a few months.

Splenic cancer

It is a malignant tumor located in the spleen, and can cause extremely serious internal bleeding.

Oral cancers

In dogs, 6 in 100 cancers are malignant tumors of the oral cavity.

  • From a fibrosarcoma,
  • Of a acanthomatous ameloblastoma,
  • From a malignant melanoma,
  • Squamous cell carcinoma.

Skin cancers

In this category of skin cancers, we find mainly in dogs:

  • Squamous cell carcinoma,
  • Mast cell tumor or mast cell tumor,
  • Malignant melanoma.

Brain tumor

Among the cancers localized to the brain in dogs are:

  • Gliomas,
  • Meningiomas.

We are talking about secondary cancer the brain when the disease is due to the spread of metastases from a malignant tumor located in another part of the body, and primary cancer of the brain when the tumor initially settles in that organ. In either case, it is still extremely difficult to cure this type of cancer and the dog’s vital prognosis is generally engaged.

Stomach cancer

It could be :

  • A tumor of mast cells, that is to say of certain cells present in the stomach,
  • Cancer of the digestive tract or adenocarcinoma,
  • Leiomyosarcomas, which are malignant cells found in the muscles that control the stomach.

Bladder cancer

He is quite rare since it only represents 2% of cancers in dogs.

Prostate cancer

This type of cancer in dogs is serious, but fortunately infrequent.

Testicular cancer

More frequent in uncastrated males, testicular tumors are mainly detected in subjects where at least one testicle is out of place, that is to say which has not descended into the scrotum. Note, however, that thetesticular ectopia is quite common but it does not always cause cancer.

Cancer of the mammary glands

This carcinoma is much more common in elderly unsterilized bitches Where sterilized late since it is influenced by hormones. Bitches with an extremely low risk of developing a malignant tumor of the mammary glands are those who have undergone sterilization before their first heat.

Bone cancer

It is called theosteosarcoma. He is among the most frequent cancers in dogs since each year, nearly 10,000 cases are recorded in this population. It particularly affects large dogs.

Soft tissue sarcoma

We are talking about liposarcoma when cancer cells attack fatty tissue and fibrosarcoma when it is the fibrous tissue that is concerned. This cancer can also affect the blood vessels (hemangiosarcoma), the tissue of the peripheral nerve sheath, striated muscles or even smooth muscles …

Lymphocyte cancer

the lymphoma affects white blood cells. As the dog’s immune system is therefore concerned, the life expectancy of an animal suffering from lymphoma rarely exceeds 12 months.

Cancer in dogs: early diagnosis increases the chances of a cure

All malignant tumor is cancer. But to confirm his diagnosis, the veterinarian cannot be satisfied with an auscultation of the animal. Complementary examinations are absolutely essential to ensure the malignancy of a tumor. Blood tests, samples of suspicious cells, or even a biopsy then, if the cancer is confirmed, imaging tests are carried out such as x-rays, scans or even MRIs. This expansion balance allows to know with certainty whether or not there is dissemination of metastases in the body of the dog.

After all these investigations, the veterinarian sets up the most suitable treatment protocol. Cancer treatment is therefore decided on a case-by-case basis (surgery, chemotherapy, radiotherapy, etc.). Many dogs are doing very well. However, you should know that the older the animal, the more vulnerable it is. When cancer cannot be cured, theeuthanasia is the only possible outcome.

Of course, if the dog is covered by a mutual health, a large part of the expenses incurred by his master can be supported by the insurance company and some formulas include reimbursement of euthanasia costs.
