My cat has a jaw lump after tooth extraction. Why is it bleeding now?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 15 years and 1 month old | 11 lbs

My cat had a tooth extracted in November. Mid December a lump appears on his jaw. He Has been to his vet 3 times since, with 3 rounds of antibiotics and steroids. He is still eating, drinking, bathing fine. This week, he started bleeding when he eats. Lump is still there and has not changed in size.

Given Simba's age, I would be very concerned that this lump may be a malignant tumor. Because antibiotics and steroids haven't help, I would recommend having blood tests, a urinalysis, x-rays, and a fine needle aspirate (FNA) done on the lump. To do an FNA, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. These tests may hopefully help diagnose the cause of the lump. Once the cause is found, the vet can discuss treatment options.
