Lymphoma is one of the most common types of cancer in pets, particularly in dogs and cats.

7. Skin Lesions and Itching

In some cases, lymphoma can manifest as skin lesions or sores that don't heal. These lesions may be itchy, causing your pet to scratch excessively. If you notice any unusual skin changes, such as redness, swelling, or sores, it's important to have your pet examined by a veterinarian.
