Your 11-year-old daughter's breast pain is very likely a normal part of puberty, caused by developing breast buds (small, tender bumps) and hormonal shifts, leading to soreness, tenderness, or aching as breast tissue grows, sometimes unevenly, and can be linked to her menstrual cycle. While usually temporary and manageable with a supportive bra or mild pain relief, it's good to check for a well-fitting bra and see a doctor if pain is sharp, persistent, or accompanied by other concerns like discharge.
Puberty. Breasts start to get bigger around the time puberty begins and often feel sore. Most females start puberty when they're 8–13 years old, and they typically start getting breasts around age 10 or 11. At first you might notice a small button-like lump beneath the nipple area.
Some are related to your menstrual cycle, but other causes can be infection, cysts or hormone therapy. Cyclic breast pain is often triggered by your natural menstrual cycle. Noncyclic breast pain causes may include: Birth control pills.
While timelines can vary, most girls get their first period within 2 – 3 years after the development of breast buds. The average age for girls to get their first period in the United States is around age 12. It's important to emphasize that periods are a normal part of growing up.
The earliest physical change of puberty for girls is usually breast development, which most often begins around 10 or 11 years. But it's perfectly normal for breast development to start anytime between the ages of 7 and 13.
The rarest cup sizes are at the extreme ends of the spectrum, such as AAA, AA (especially with small bands like 28AA, 30AA), and very large sizes like G, H, and beyond (e.g., 28G, 30G, 36G), as stores focus on common core sizes (32-38 bands, A-DD cups) and these extremes are harder to find in mainstream retail but available from specialty brands. While 32A seems common, true 32A fit is rare, as many women need smaller bands or different cup volumes, making smaller/larger true sizes less represented in general stock.
The only way to permanently change breast size is through cosmetic surgery, which comes with its own risks (and expense). Doctors usually prefer that girls wait until development is complete before getting surgery.
How do you know when the first menstrual period will start?
Typically, breast development begins around age 8 to 13, with the most rapid growth occurring during early adolescence. By the age of 15 to 17, most girls have reached their adult breast size, although some may continue to experience minor changes into their early twenties.
During Puberty Girls Grow Fast and Early
Unlike boys, their fastest rate of growth occurs early in puberty. They also gain more fat than boys in preparation for their menstrual cycle. They go from gaining about 5 pounds a year before puberty, to 12-23 pounds during puberty as shown below.
As you exercise more, you may lose weight, causing fat cells to shrink. Since the breasts are primarily fatty tissues, this can lead to a reduction in breast size. Exercise can also strengthen and increase the size of the pectoral muscle. In women, these increases are often minimal due to lower levels of testosterone.
Breast buds are small, disc-shaped lumps felt under the nipple and areola. Any lump found under the areola is a breast bud until proven otherwise. Breast symptoms in newborns are also covered. Other symptoms: breast lump, breast redness and nipple discharge.
Due to hormonal shifts, one breast may swell more than the other, resulting in temporary or permanent size variation. Women may experience changes in the size and shape of breasts due to pregnancy and breastfeeding. Women may also battle with lopsided milk output, causing one breast to be bigger than the other.
In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18. However, in some cases, breasts can continue to grow into a woman's early 20s.
Aching, itching or tender breasts
As your breast buds grow, you may notice tingling, aching or itching in your chest. Your nipples may swell or become tender. This is all normal. After your periods begin, the changing hormones may make your breasts feel tender, painful or sore a week or so before your period starts.
Nipple colour can vary all the way from light pink to dark brown, while the texture can be smooth or slightly bumpy. This may also change day to day depending on your hormones and other factors. The areola (the pigmented skin surrounding the nipple) can also vary in size, colour, and texture.
Small breasts are usually due to genetics, hormones, and body fat, but can also be affected by weight loss, age (menopause), or pregnancy, with factors like clothing fit influencing appearance; if you have sudden changes or concerns, a doctor can rule out conditions like micromastia or hypothyroidism.
Generally, the first major signs of puberty are getting taller and the beginning of breast development. Rapid changes in a girl's height happen later.
Genetics and environment both play a role in triggering menarche: Heredity: Your genes influence when you get your first period. People commonly get their periods when their mother did. Hormones: Hormones in your brain and your sex organs regulate your menstrual cycle and play a role in menarche, too.
Most adolescents get their first period between ages 10 and 15. Twelve is considered an “average” age for menarche — the start of the menstrual cycle. Some individuals may find that they begin their period around the same age that other family members had theirs, but this is not always the case.
Pubic hair development (“pubarche”) usually happens 1 to 2 years before the first period. The average age for pubarche is 11.6 years old.
When the ovaries start to make and release (secrete) estrogen, fat in the connective tissue starts to collect. This causes the breasts to enlarge. The duct system also starts to grow. Often these breast changes happen at the same that pubic hair and armpit hair appear.
You should aim to perform a breast self-exam every month.
Yes, diet and exercise may contribute to a reduction in breast size by supporting overall body fat loss, though results can vary between individuals. Since breasts contain fatty tissue, they may decrease in size with overall weight loss.
