Is breast growth painful?

Girls in puberty will experience many changes in their bodies, the most obvious of which is breast development. Due to the strong secretion of hormones in the body during the development stage, it is easy to stimulate the breast tissue and cause breast pain. Girls who have no experience and do not understand the situation are more afraid when faced with this situation, worrying whether there is something wrong with their body. In fact, it is normal for breast development to cause pain during puberty, so there is no need to worry.

Breast development

The time when women's breasts begin to develop varies depending on factors such as region and race. For most women, breast development begins between the ages of 8 and 13, and fully matures between the ages of 14 and 18. Breast development usually starts from the left side, and it takes about 3-5 years from the beginning of development to full maturity.

The earliest breast pain in girls usually occurs between the ages of 9 and 13. At this time, girls' breasts begin to develop and they will have a slight feeling of pain. After menarche, the swelling and pain will disappear on its own as the breasts mature. At this time, a harder lump can be felt under the nipple and areola. The boundary is not clear and it is slightly painful to touch. It is about the size of a bean or a peanut. As age increases, this lump gradually grows larger, becomes softer, and grows diffusely. Suggestions: It is recommended that breast pain that occurs during breast development should be considered physiological breast pain. There is no need to be afraid and no treatment is required. Most girls will experience this phenomenon during breast development. For this reason, we should explain clearly to children that this is a phenomenon in human development and eliminate their fear.

Principles of Breast Development

The growth and development of the breasts are mainly affected by a variety of hormones in the reproductive endocrine axis, such as gonadotropin and prolactin secreted by the pituitary gland, and estrogen and progesterone secreted by the ovaries; in addition, the hormones secreted by the adrenal glands and thyroid glands, and growth hormone secreted by the pituitary gland are also needed for the breasts to develop fully and completely.

The size of breast development is affected not only by the effects of estrogen in the body, but also by genetics, environmental factors, nutritional conditions, obesity, physical exercise and other factors. If the mother has small breasts, her daughter will most likely have smaller breasts as well. This is due to genetic factors. It is also difficult for thin girls to have full breasts. Small breasts may also be related to the early or late development. Although the breasts are small, as long as the reproductive organs develop and menstruation are normal, it will not affect the breastfeeding function and fertility in adulthood. Generally speaking, the early or late development of breasts does not affect the speed of future development, nor does it affect the size and shape of the breasts in adulthood. The development of a girl's breasts is the first sign of the onset of puberty.
