Dog Breast Cancer

•    There are various types of breast tumors in dogs; half of these are benign and the other half are malignant. A few common forms of benign tumors include benign mixed mammary tumors, adenomas, duct papillomas, and fibroadenomas. Meanwhile, malignant breast tumors are carcinomas, adenocarcinomas, fibrosarcomas, osteosarcomas, and malignant mixed tumors.

•    Researchers have explained that sex hormones in dogs play a role in the sensitization of breast tissue cells. These occurrences cause the genes of tissue cells to mutate and turn into cancerous cells.

Middle-aged or older female dogs that are unspayed have higher risks of developing breast cancer.
•    A puppy that is spayed before its first heat cycle, or around six months of age, will have a lower risk of breast cancer.


•    Dogs have five mammary glands. Each gland has its own nipple on both the right and left side of its abdomen. Breast cancer can occur in all glands, it is more common in the 4th and 5th glands.
•    Breast cancers start with a solid mammary tumor or as multiple swellings or solid mass. When these tumors first appear, they look like small pea gravel under the skin. These are also hard and do not move when touched under the skin.
•    Signs of malignant tumors include:
o    Rapid growth
o    Irregular shape
o    Firm attachment to the skin or underlying tissue
o    Bleeding
•    Meanwhile, benign tumors are smooth, small, and have slow growth.


•    Breast cancer in dogs is among the preventable forms of cancer.
•    There is a close, direct, and well-documented link between early spaying of female dogs and a decrease in incidence of developing breast cancers.

•    Dogs that are spayed before their first heat cycle have the least chances of developing breast cancer.
•    Dogs that are spayed after their first heat cycle but before they turn 2.5 years old have a higher risk.
•    However, female dogs that are never spayed or spayed later in their lives have the greatest risks.
•    Early spaying is considered one of the efficient and best measures pet owners can do to improve the overall health condition of dogs. It can spell a difference between long and short life span.


Dogs diagnosed with cancers may have a few treatment options. They are the following:
•    Surgery. Unless the female dog is old, surgical removal of the malignant mass can reduce the spread of cancer in 50% of all breast cancer cases. Of course, there are other factors that determine the result of surgery, including the stage of time which the surgery is performed. The surgery may take out only the mass. At times, the mammary tissue and lymph nodes are removed as well.
•    Chemotherapy
•    Radiation therapy
•    Natural remedies including supplements, complementary and alternative treatment for canine breast cancer in the form of herbs and homeopathic remedies.
