Should I be concerned?? Just found this on my breast

I do get eczema so at first I ignored the small patch, then tonight I looked closer and realized it’s a patch of tiny little bumps (texturized) so of course I tried squeezing them and a small amount of blood and a watery-like clear liquid came out. (the red is the blood I hadn’t wiped it all off) I just realized my skin surrounding the bumps is red as if there’s a rash, I’m not sure if it’s an actual rash or if it’s from me trying to see what the bumps were.. I’m only 20 so now my head is racing thinking it’s an early sign of breast cancer. Has anyone had something similar?? Any nurses on here? Gonna monitor it over the next few days for any changes
