Why is my cat acting strange with a head lump and cancer history?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed

My white female cat has a lump formed on the side of her head below the ear (covered by fur), this cat has a history of skin cancer in its ears (has had the tips removed) and gets into fights often. The cat's mood also seems a little down, and is acting strange. For example, she usually likes being pet on the head but now has been flinching at the contact. thanks .

If you could post a picture of the lump in might help with deciding what it could be. Based on Snowy's history she could've got into a fight and have a deep abscess forming, it could be another type of cancer, or maybe a soft tissue injury. With her history of having various cancers as well as the potential for this to be an infection I recommend she get examined by her veterinarian. In the meantime do not give any human pain medication as it can be very toxic and even deadly to cats.
