What is canine breast cancer?

Cancer is called a disease caused by a tumor that invades, contaminates and destroys cells in the body. In this case, breast cancer can be described as a tumor originating from one of the dog’s breasts.

Breast tumors can be benign or malignant If they are benign, it will simply be enough to remove them to prevent them from proliferating. If they are malignant, it is when we speak of cancer, since they are invasive and destructive.

They occur mainly in females over one year of age and the older they are, the greater the probability of suffering from it. Some specimens of male dogs also suffer from breast cancer, although in a much smaller number.

Treatments for Breast Cancer in Dogs

Dogs suffering from cancer (a diagnosed malignant tumor) should be screened for metastasis or not. Metastasis is the spread of cancer cells to other parts of the body, generally organs such as the lungs, liver, etc …

In case of metastasis, the common treatment for breast cancer usually consisting of chemotherapy sessions, loses much effectiveness and it is advisable to consider the quality of life of the dog.

If there are no metastases, chemotherapy can cure our dog. About fifty percent of dogs treated with chemotherapy for breast cancer manage to beat the cancer and survive.

However, our vet must assess what type of cancer our dog has, as some, such as canine inflammatory carcinoma, are extremely aggressive and the use of any treatment is rarely recommended.

On the other hand, we should not consider the possibility to sacrifice our dog unless our vet recommends it to us.

How to prevent breast cancer

Despite the numerous rumors that it is necessary to wait for the dogs to have a litter before being sterilized, it is advisable to sterilize them as soon as our vet recommends it, which is normally from one year of age.

It is not necessary for a bitch to pass its first heat or have a litter to be sterilized, since the sooner the sterilize, before we will reduce the risk of suffering diseases such as breast or uterine cancer.

On the other hand, administering a high-quality diet and exercising in places free of contamination, such as walking in the fields or mountains, are very healthy habits that reduce the risk of disease.
