Bloodhounds

I have the opportunity to purchase a 6 week old blood hound. She has a fatty mass in her belly and it will need to be removed. I was told this can be done when she is spayed. I wonder if this is a huge deal, or something that is not that big of a deal. I don't mind investing in her, but if this is the beginning of a lifetime of health issues I would be bothered. I mass has not impaired her growth on any level. Any thoughts?
