Adolescent Breast Problems
Several breast growth patterns can be troubling to the adolescent and her
family. Among these are:
- Unusually early breast development
- Unusually delayed breast development
- Unusually large breasts (Mammary hypertrophy)
- Unusually small breasts
- Asymmetrical breast growth
- Breast lumps
Initial breast development occurs on average at age 9, with the appearance
of a breast bud. The normal range for breast bud appearance is from age 8-13.
It is not rare for one bud to appear up to 6 months prior to the second bud
appearing.
Breast growth is then progressive, with enlargement of the breast tissue,
areala and papillae, and change in shape and contour. By age 18 breast
development is usually complete.
Premature thelarche is breast development prior to the age of 8 (and in the
absence of pubic hair development). These children are evaluated to rule
out estrogen-producing ovarian tumors, ingestion of estrogen-containing
compounds, and the rare, true precocious puberty.
Delayed thelarche reflects absence of any breast development by age 13.
Asymmetrical breast growth during adolescence is the rule rather than the
exception. Reassurance is given that the asymmetry usually evens out by the
time of full maturation. Even at maturity, breasts are rarely 100%
symmetrical, so minor degrees of asymmetry are expected. Because the breasts
are continuing to grow and change, surgical intervention for asymmetric
breasts is generally delayed until after age 18.
Mammary hypertrophy can be a distressing symptom. Because growth and
development continues for a long time, surgical intervention, if contemplated
is postponed until the breasts are fully mature.
Breast masses in adolescents are essentially 100% benign. Because of this,
surgery (excisional biopsy or fine needle aspiration) is almost never
warranted. Further, the surgical disruption of architecture can be disfiguring
as the breast continues to mature.
