Dog Biopsy is Black - What Does it Mean

My dog had a biopsy to determine if he has cancer. We do not have the results back yet. He is a dachshund, 8 years old has trouble with urination. He was neutered about five years ago. @hat else would make the prostate black?

Editor Suggestions - Waiting for Biopsy Results


If you are asking because you have seen imaging of your dog's prostate and noticed it appeared black, it's important to note that in medical imaging, the color or shade of a tissue doesn't necessarily indicate a specific disease or condition. The appearance of tissues in imaging studies can vary depending on the type of imaging technique used (such as ultrasound, CT, or MRI) and the settings of the machine.

In general, a number of different factors can affect the appearance of the prostate on imaging:

Infection: A bacterial infection can lead to prostatitis, which could potentially alter the appearance of the prostate on an imaging study.

Benign Prostatic Hyperplasia (BPH): This is a common condition in older, unneutered male dogs, although it can also occur in neutered males. BPH involves non-cancerous enlargement of the prostate.

Prostatic cysts or abscesses: These are fluid-filled sacs that can develop in the prostate. They can be caused by a variety of factors, including infection or blockage of the ducts in the prostate.

Calcification: This is a process where tissues harden due to the deposition of calcium salts. It can happen in various tissues in the body, including the prostate, and might potentially alter its appearance on imaging.

Neoplasia: This refers to abnormal, uncontrolled cell growth, which can be benign (non-cancerous) or malignant (cancerous). In dogs, prostate cancer is relatively rare but can occur.

These are just some of the potential causes of changes in the prostate. Remember, the appearance of the prostate on imaging doesn't necessarily mean there is a problem. Sometimes, normal variations in anatomy can cause the prostate or other tissues to appear differently.

Please wait for the biopsy results and discuss them with your veterinarian. They are the best person to guide you through this process and provide the necessary information and advice for your dog's specific situation.

All the best,
