Thank you for submitting your question regarding your cat. I recommend that she sees her veterinarian. She could have an infection on or under her skin. If this is not the case, then she could have a mass that has grown. In this case, she would need a procedure known as a fine needle aspirate. The veterinarian would use a small needle to collect a sample of cells to evaluate under the microscope. This will help to diagnose the mass and determine if surgical removal is necessary. I hope this information helps!
