Okay, kiddo, so sometimes a person's breasts (that's the part of the body with the milk-making glands) can grow bigger than they want or need. This is called breast hypertrophy. It can happen because of things like genetics, hormones, or weight gain.
When someone has breast hypertrophy, it can cause problems like back pain, shoulder pain, and difficulty finding clothes that fit well. Some people might also feel self-conscious about having such large breasts.
The good news is that there are options to help with breast hypertrophy. Sometimes, doctors might recommend special exercises or physical therapy to help with the pain. Other times, surgery might be an option to reduce the size of the breasts.
It's important to remember that everyone's body is different and there's no "right" size for breasts. What matters most is that someone feels comfortable and healthy in their own skin.
