Prostate Cancer (Adenocarcinoma) in Dogs

The prostate gland is an important part of male reproductive system. A number of important and essential enzymes including calcium and citric acid are present in it. The gland also plays an important role in protection and motality of the sperm. The liquid secreted by the prostate gland aids in the liquefaction of semen after ejaculation, and in the protection of sperm in the vagina.

Adenocarcinoma is a malignant tumor that originates in the glandular tissue, in this case, in the tissue of the prostate gland. The tumor has the capability of growing and metastasizing (spreading) rapidly to other parts of the body such as lungs, lymph nodes and bones. This tumor is seen in both the intact and neutered dogs. Though the tumor can affect any dog, it is mostly reported in larger breeds and in older dogs between the ages of 9-10 years.
