Early breast development in overweight girls: does estrogen made by adipose tissue play a role?
Here's an overview of the major physical changes girls can expect as they go through puberty:. Girls usually begin puberty between the ages of 8 and 13 years old. The earliest sign of puberty in most girls is the development of breast "buds," nickel-sized bumps under the nipple. It is not unusual for breast growth to start on one side before the other.



Health Conditions
It has been proposed that estrogen synthesized by adipose tissue may be contributory, yet OB do not have higher serum estrogen levels than NW matched on breast stage. We hypothesized that estrogen synthesized locally, in mammary fat, may contribute to breast development. This hypothesis would predict that breast development would be more advanced than other estrogen-sensitive tissues as a function of obesity and body fat. Tanner breast stage did not correlate with breast morphological stage and led to misclassification of chest fatty tissue as breast tissue in some OB.





Jump to navigation. Breast development is caused by hormones released by the ovaries at puberty. These hormones cause fat to accumulate, causing your breasts to enlarge. The first sign of breast development is slight swelling under the nipple, a stage of development called breast buds.
