Mammary Tumor Figure 2

Figure 2: Mammary tumor
Post-op photos of incision site

The photos shown here were taken following the removal of a mammary tumor.

Pooka seen here is approximately 18 months old. It is common to see mammary tumors start to develop in this age group. The area of mammary tissue in rats is extensive, and as seen below, shows the location of this tumor removal being to the right and lateral of the abdomen.
Depending on tumor size, and the involvement, a long wide excision may be necessary in removing all of the tumor, since they can grow to be quite large.

Due to the location site on the body, steel sutures tied individually were chosen over other monofilament or multifilament type suture material, and an Elizabethan collar applied to further prevent this rat from chewing or licking the incisional area. It is generally not recommended in most cases to use an Elizabethan collar in rats since it prevents them from holding their food, and inhibits the intake of nourishment.
