Swollen lymph nodes
Jul 26, 2018
These “glands” are located all throughout the body but are most easily detected behind the jaw or behind the knee. When these lymph nodes are enlarged they can suggest a common form of cancer called lymphoma. A biopsy or cytology of these enlarged lymph nodes can aid in the diagnosis. Reaction at vaccine site: Vaccine associated sarcomas can occur in cats and there is an easy to remember “rule” that owners should follow. The “3-2-1” rule of thumb is that any mass that persists for more than three months after vaccination; any lump that is larger than two centimeters (about 1 inch) in diameter; or any lump that is increasing in size one month after vaccination should be evaluated by a veterinarian.
