Hi, I'm a 16 year old female and I've noticed a white, pimple-like spot on my right nipple just last week. It wasn't protruding very much and it didn't cause any pain, though I felt only slight discomfort. The while dot also resembled a pimple so I tried not to mind it so much until recently. It suddenly began to be painful to the touch. Also, if my shirt so happened to brush against the spot if I wasn't wearing a bra, it would hurt as well. Just today, it changed color from a white dot to something reddish brown, much like the color of that of a dried up scab. I don't know if this is actually a pimple or something that normally occurs. I've already informed my mom and she said to wait on it. Otherwise, I can have it checked. I'm partly being rather paranoid because I have knowledge that there were past cases or breast cancer and the like in my family. Insights would be appreciated. Thank you!
