A mass (lump) in the mammary glands is the most common sign of breast cancer. The fourth and fifth mammary glands (glands closest to the groin) are most commonly affected. The mass may be normal color, red or purple, soft, hard, and in some cases ulcerated.
What do mammary tumors feel like?

How long can a dog live with a mammary tumor?
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 happens if a mammary tumor bursts?
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.
Are dog mammary tumors painful?
Inflammatory mammary carcinoma is red, firm and very painful. This is unusual for a mammary tumor. Unfortunately, there is no good treatment for inflammatory carcinoma. Radiation therapy, pain medications and non-steroidal anti-inflammatory drugs can be used to control pain.
Are dog mammary tumors hard or soft?
The size of the mass(es) and their appearance may vary, but they are usually firm and nodular. Occasionally the skin over the mass may ulcerate (open) and bleed, and the affected area may feel warm to the touch and become painful. The mammary gland may even develop a discharge.
What does a cancerous lump feel like?
Cancerous lumps are usually hard, painless and immovable. Cysts or fatty lumps etc are usually slightly softer to touch and can move around.
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.
Are mammary tumors in dogs cancerous?
Approximately 50% of all mammary tumors are malignant (cancerous) and of those, 50% have spread at the time of diagnosis. Inflammatory mammary carcinoma is highly malignant, but comprises less than 5% of all mammary tumors.
How much does it cost to have a mammary tumor removed from a dog?
Cost of treatment
If only one mammary gland needs to be removed, the surgery will cost approximately $500. For longer procedures, such as a full mastectomy, we charge between $800-$1,200.
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.
What does known malignancy mean?
The term “malignancy” refers to the presence of cancerous cells that have the ability to spread to other sites in the body (metastasize) or to invade nearby (locally) and destroy tissues.
What happens if you don’t remove a mast cell tumor?
The most significant danger from mast cell tumors arises from the secondary damage caused by the release of these chemicals, including ulcers within the digestive tract, hives, swelling, itching and bleeding disorders. Sites where the tumors are removed sometimes fail to heal and can become difficult to manage.
