So a few hours ago, I noticed my nipple leaked a liquid that was yellowish orangish brownish kind of color and from little openings aroud the middle, so it didn't come from the middle. around it. I'm not pregnant (I'm 13) and I am on my period. Is it normal or should I be concerned? Because It only happens on the right, the left barely does and when it does its clearish white, and it comes from the center. I read that it may be a sign of breast cancer, and i think i feel a little lump under that hard (bone?) in my breast. could this be breast cancer? can a 13 year old get breast cancer? I'm going to the doctor tomorrow. but I just want to have an idea.
