What is the usual age cutoff for precocious puberty in girls?

The usual age cutoff for precocious puberty in girls is defined as the onset of secondary sexual characteristics before the age of 9. However, specific guidelines often consider precocious puberty in girls to be the appearance of breast development, which typically occurs around 8 years old. Therefore, while the selected answer of 7 years seems to align closely with these guidelines, the focus on 8 allows for the distinction that positions it as the standard threshold for identifying cases that warrant further clinical evaluation or intervention. This means that 8 years serves as a practical cutoff point for assessing pubertal timing, guiding clinicians in their evaluations and decisions regarding treatment options or referral to specialists.
