if it makes you feel any better, i have a huge breast cancer risk and have 3 benign lumps currently. and have had 1 removed and 1 cyst go away in its own. there's almost no need to worry about it until you get an ultrasound. with how young we are it's most likely a fibroadenoma or a cyst. you're doing a great thing getting it looked at so soon, wishing u the best
