My cat has a soft lump near her nipple. Could it be a tumor?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 12 years and 1 month old

Hi, I'm very concerned because I've discovered a very tiny lump (2 mm in diameter) at around 0.5 inch distance from my cat's nipple. The lump is very soft and it is not actually under the skin and is not attached to it. I think it's located somewhere on her chest muscles (rib cage). The lump is also not visible externally. The nipple itself appears to be normal. Should I be worried or is it unlikely to be a tumor?

Hi. Poor Martha. Yes, any lump around the mammary area is concerning until proven benign. Especially if she was spayed later in life. The sooner these get checked and then removed if needed, the better the outcome. I would definitely recommend getting it checked and having them take a needle sample to look at the cells that it is made up of. This will help guide the next steps. If you would like to discuss further, you can open a consultation if you'd like. Good luck.
