My cat has a lump on his shoulder and fur loss. Should I see a vet?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Female | spayed | 12 years and 7 months old | 10 lbs

Found a small flat raised lump on left shoulder 2 weeks ago. Vets trips are extremely traumatic for him so I have waited but I am now more worried that if it is something bad I don't want to delay. Not inflamed no apparent pain but his fur is missing over it. I initially thought maybe just a insect bite or a rub but it is not going away and the fur is not growing back. I'm obviously worried about a cancerous growth and think I need to get him to a Vet but would appreciate your comment.

It's hard to tell the size but it looks like it may be a benign wart or growth. It appears to be more on the surface of the skin which is good, and it is well defined. Cats do get malignant skin growths so it is a good idea to have your veterinarian examine it and feel underneath also. They can easily remove this if necessary and do a biopsy. I'm not overly concerned looking at the photo but it's best to be sure. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Louis.
