Pet's info: Cat | American Shorthair | Female | spayed | 1 year and 5 months old | 7 lbs
Hi! I just adopted a 1.5 year old female cat but noticed she had a soft lump on her belly. I have contacted the shelter who I got her from and they plan on biopsying the lump next week but I am wondering the likelihood of it being mammary cancer.

Having done thousands of surgeries at shelters, I would venture to guess that the lump is likely a fluid swelling around the spay site. These are usually not a problem and will eventually go away on their own. However, it will still be good to get it checked out, because they occasionally develop infections or hernias. The chance of mammary cancer is very low in a cat that young and I think less likely considering that she probably got spayed recently. I hope that helps and Luna gets better soon. Also, good on you for adopting!!
