What percentage of unspayed dogs get mammary cancer?
One in four unspayed dogs will develop mammary cancer. A female dog that is spayed prior to her first heat cycle has almost a zero chance of developing mammary cancer. If she is spayed after only one heat cycle, her chance of breast cancer rises to seven percent.
What percentage of intact female dogs get mammary cancer?
The risk is even higher for female dogs than it is for women. Mammary tumors in female dogs account for 42 percent of all diagnosed tumors, with a lifetime risk of 23 to 34 percent, according to the Veterinary Society of Surgical Onocology (VSSO).
How common are mammary tumors in dogs?
Mammary tumors are extremely common in dogs; approximately 50% of them are malignant. Mammary tumors are more common in intact than in spayed females; in fact spaying before the first or second heat cycle significantly reduces the risk of developing mammary tumors. Median age on presentation is 10 to 11 years.
How can you tell if a female dog has breast cancer?

How Long Can dogs live with mammary cancer?
The remaining 50% of dogs with malignant tumors are at risk for the spread of their tumor. This leads to illness and poor quality of life, with survival times usually less than one year. Dogs with inflammatory mammary carcinoma and mammary sarcomas have a poor prognosis, on the order of weeks to months.
What does a mammary tumor look like on a dog?
The most common clinical sign of a malignant mammary tumor is one (or more) palpable masses underneath the skin of the abdomen. They may be next to or within the nipple and follow along the mammary chain (see illustration). The size of the mass(es) and their appearance may vary, but they are usually firm and nodular.
Can my dog survive mammary tumors?
Dogs can live several years after complete removal of some malignant mammary tumors. So once a mass is found, having surgery to remove it earlier is better. Mammary tumors can be largely prevented by spaying before 6 months of age or before your pet’s first heat cycle.
How do you get rid of mammary tumors in dogs?
Surgery is by far the best treatment for dogs with mammary tumors. If biopsies are not taken prior to surgery, to determine if the tumor is benign or malignant, a large surgical excision is the treatment of choice to ensure complete removal of the tumor.
How much does it cost to have a mammary tumor removed from a dog?
Cost of the surgery
Shorter procedures where local excision only occurs, costs approximately $800. Longer procedures, such as full mastectomies can cost $1,000- $1,600.
Can a mammary tumor burst?
At first the tumor is small and may feel like a pebble or dried pea. The tumor should be removed as soon as possible in hope of removing it completely. If left alone, mammary tumors get larger and harder and ultimately burst through the skin creating a smelly, infected ulcer.
How much would it cost to remove a tumor from a dog?
Cost of Surgical Tumor Removal in Dogs
For a simple skin tumor removal, the cost can vary from $180 to 375, whilst more complex internal tumors run $1,000- $2,000 and upward. Costs vary depending on the surgical time and the complexity of the surgery.
