Young teenager; sensitive, large lumps in breasts

It might not be anything but you should go see a doctor because it is always best to be 100% sure. I know it can be scary going to the doctor but after you go get it checked you will feel so much better having all those worried thoughts out of your mind. Breast are kinda a little lumpy inside so it in highly possible its normal. but it's safer to double check.

you should definitely talk to a doctor about this

If they've been there for a while I'd see a gynecologist about it.

If the lumps and/or pain come and go with your menstrual cycle then they are probably normal but you need to see a doctor.

IT IS NORMAL, but go see a doctor if you are worries

Most likely benign cysts caused by your hormonal spikes. Are you sure they are lumps and not the usual breast muscles? The soreness is typical for your age...ask your mom or a doctor to clarify. Better safe than sorry.

My GYN told me that we women have pebble-like knots throughout our breasts and is normal all thru teens and early 20s.

It's actually pretty common and can stem from having fibrocystic breasts. I started having that problem when I was 13. See a gynecologist and they can figure out the problem and give you solutions.
