Changes to your breasts


It’s natural for girls to wonder about their breasts: Are they too big? Too small? If your breasts are large, they may get you unwanted attention. If they’re small, you may worry that they’ll never grow. Remember that your breasts don’t need to look like your friend’s breasts or a magazine model’s breasts. The world would be boring if everyone looked the same!

Here’s some more info on your changing breasts:

What happens to breasts during puberty? top

Throughout puberty, you will experience changes in your breasts. The first change is developing a very small bump under the nipple. Early on, you may also notice that your breasts feel a little itchy or achy. Later on, they also may feel tender or sore during your period.

Keep in mind that it is very common for your two breasts to be different sizes, especially as they first start to grow. Other people can’t tell that your breasts are different sizes. Give your body time to grow at its own rate and in its own way. Vitamins, herbal teas, and creams — even exercises — won’t change the size of your breasts.

What about lumps and other changes? top

Most of the changes your breasts will go through are normal. Let your doctor know if you find a lump or have a pain that you are not sure about. Although lumps are common in young women, keep in mind that it is very rare for the lumps to be cancer.

Should I wear a bra? top

Wearing a bra can help support and protect your breasts. If you find that exercise is not as comfortable when your breasts start to grow, try wearing a sports bra with a snug fit for support.

Are you having a hard time finding a bra that fits well? Often, you can get help in a department store or special bra store. There are certain steps people there can take for measuring your body to get a good fit.
