Mammary or Breast Cancer

Breast cancer represent approximately 25-50% of all tumors in dogs and are the 2nd most frequent class of cancer after skin tumors. In cats, breast tumors are the 3rd most common cancer.

The average age for dogs is 10 years with females being the most affected over males. Unfortunately for males, if they do have these tumors they are usually highly malignant (spread to other body tissues). Tumor size plays a significant role in determining the prognosis of your pet. Therefore, the earlier the tumor is removed and the smaller it is, the better chance your pet has of surviving.

Unfortunately, cats that present with mammary masses have a 80-90% chance of being highly malignant. The average age is 10-12 years. Therefore it is important to take your pet to the vet as soon as you feel a lump.
