This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Archie to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

    Anytime a new mass is noticed, I always recommend having it evaluated to see what it is and if anything needs to be done about it. Unfortunately, we can't tell anything about a mass by just looking at it. Even when it feels like a lipoma, it can sometimes fool us. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign lipoma, you might not need to do anything about the mass at all, but if they see cells that worry them, they might recommend removing the mass. It is common for lipomas to grow slowly over time, but they should always be re-examined if they are growing quickly or changing texture. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
