Understanding Bumps and Cysts on Pet’s Skin

As pets age, lumps and bumps may arise on the skin

As pets start to age, various lumps, bumps and cysts can arise. Many times these can appear suddenly and can have various appearances from raised hairless overgrowths of tissue, to bumps felt under the skin. The most common benign bumps in pets include overgrowths of fatty tissue known as lipomas, and warts. Other common benign bumps include various types of cysts that can sometimes discharge pasty fluid on the skin surface.

Other lumps can have various appearances and can occasionally bleed. While the softer, fatty and freely movable over-growths can be diagnosed as lipomas by a veterinarian, the best way to make sure that these bumps and cysts are benign is to have a veterinary exam. During such an exam, the veterinarian may perform a needle aspirate, where the vet or veterinary pathologist at an outside laboratory examines cells under the microscope for diagnosis. A needle aspirate can be done without any sedation in the veterinary office.

Other times, a surgical excisional biopsy is necessary in which surgery is performed while the pet is under anesthesia. Rather than watching and waiting, if a bump or cyst is growing quickly, it is always best to have a veterinary exam to perform one of these diagnostic tests so your pet receives the best treatment. LearnMoreButton-lipomas
