Please help I’m worried..

It started off with one. And now there are two more. They seem to be ingrown pimples. But I’m not sure. I popped one and some pus came out as if it was pimple and I tried to pop another and it just hurt the f out of me and nothing came out. What do you guys think this could be? 😞 is this early signs of breast cancer? I’m thinking the worst.

This is going on on the bottom Crees of my right boob. :/ yes
