Bleeding nipple?? NOT breastfeeding

I took my shirt off today and I have a white tank top under and I noticed some small spots of blood so I thought that’s weird where Could it be coming from? So I checked on my nipple because that’s where the spots were located and I squeezed a little and there’s blood!!! 🙁 I’m not breastfeeding, I haven’t hurt myself I have an 11 month old baby but he’s formula fed only so I’m worried what that can mean? Everywhere I read it says breast cancer 😩
