Mammary tumors can be benign (non-cancerous) and malignant (cancerous). The two forms of the disease have different diagnostics, treatments, management, and prognosis.
Are all mammary tumors 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 do you tell if a dog’s tumor is benign?
A fine needle aspirate is done to confirm the benign nature of the tumor, and the tumor is usually only removed if it’s bothersome to the dog’s normal movement or activity, Swanson says.
What does a mammary tumor feel like?
The way that lump feels can provide plenty of information. Breast cancer tumors are rigid with firm, angular edges. They feel more like rocks than grapes. “A tumor won’t be smooth like a cyst.
How long can a dog live with a benign mammary tumor?
Dogs with benign tumors had a median survival time of 114 weeks as compared with 70 weeks for those with carcinoma. More than half the dogs with mammary carcinoma were surgically cured, and those that were destined to die of their malignancy did so within 1 year of surgery.
Do benign mammary tumors in dogs grow?
Some benign tumors may never change and remain small and benign over time. Other benign mammary tumors may progress, become malignant, and develop new tumors in new locations in the mammary chain.
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.
Why do female dogs get mammary tumors?
It is well known that exposure to specific hormones, namely progesterone, increases the risk for developing mammary cancers in dogs. This is because progesterone stimulates growth factors (molecules that stimulate specific processes in the body) that cause mammary cells to multiply (i.e., replicate).
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.
Can puppies get mammary tumors?
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.

Fibroadenomas are solid, smooth, firm, noncancerous (benign) lumps that are most commonly found in women in their 20s and 30s. They are the most common benign lumps in women and can occur at any age.
What makes a tumor benign?

What does it mean when something is benign?
Benign refers to a condition, tumor, or growth that is not cancerous. This means that it does not spread to other parts of the body. It does not invade nearby tissue. Sometimes, a condition is called benign to suggest it is not dangerous or serious.
Can benign tumors in dogs grow quickly?
Lipoma – Lipomas are benign tumors composed of fat, and they are usually found under the skin of middle-aged to older dogs. They tend to grow slowly and don’t cause a problem for most dogs.
Are mammary tumors painful in dogs?
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.
How much does it cost to remove a tumor from a dog?
$500 to $1,000 is a fairly typical expense for a mast cell removal. If a board certified surgeon is elected due to difficult access to the site (for internal tumors or for less surgically amenable locations on the skin), costs are likely to increase two- to five-fold.
