A Simple Test Can Reveal What a Lump Is Really Hiding
Finding a lump on your dog or cat can be worrying. Some growths remain unchanged for years, while others develop quickly or begin to look different. Although it’s natural to hope the lump is harmless, appearance alone cannot reveal what’s happening beneath the surface.
The only way to identify many masses, lesions, or enlarged lymph nodes is by examining the cells or tissue.
1. A Lump Appears Suddenly
A new lump doesn’t always point to a serious problem, but any new growth deserves attention. Your veterinarian can determine whether further testing is appropriate instead of relying on appearance alone.
2. The Lump Keeps Growing
If a mass becomes larger over days or weeks, it’s time for an examination. Changes in size may indicate that additional testing, such as fine needle aspiration or a biopsy, is needed.
3. A Sore Doesn’t Heal
Skin lesions that remain open or fail to improve after a reasonable amount of time should not be ignored. These areas often require closer evaluation to determine the cause.
4. You Notice an Enlarged Lymph Node
Swollen lymph nodes can develop for several reasons. Fine needle aspiration allows your veterinarian to collect cells from the area so they can be examined by a veterinary pathology laboratory.
5. The Growth Changes Shape or colour.
A lump that changes in appearance deserves prompt attention. Even small changes can provide valuable clues that further testing may be worthwhile.
6. A Fine Needle Aspiration Doesn’t Provide Enough Answers
Fine needle aspiration (FNA) collects cells using a thin needle for cytology analysis. It is commonly used because it is minimally invasive and can help identify many types of masses. If the results are inconclusive, a biopsy may be recommended to collect a larger tissue sample for histopathology.
7. Your Veterinarian Recommends a Biopsy
A biopsy removes a small piece of tissue, or occasionally the entire mass, so a veterinary pathologist can examine the tissue structure in detail. This often provides more information than cytology alone and helps guide the next steps in your pet’s care. Results are commonly available within a few days after the laboratory receives the sample.
Don’t Wait for a Lump to Change Again
Many lumps and skin growths look alike from the outside. Some are harmless, while others require prompt attention. Waiting for obvious changes may delay finding out what the growth actually is.
Early assessment allows your veterinary team to replace uncertainty with clear laboratory findings.
