Below are the most common possibilities of nipple discharge
in adolescent females. Please remember these are only possibilities and do not
have to fit YOUR diagnosis; in order to find out what is causing your symptoms,
you need to visit your doctor who will get detailed information and examine you
thoroughly.

1- Nipple discharge in your
age adolescent is usually benign in nature, and may assume different colors: white,
clear, red, yellow, green, or brown. Typically it is secondary to local
irritation or stimulation, pregnancy, or an adverse effect of certain
medications including antipsychotics, oral contraceptives, or opiates.

2-  Ductal ectasia, a condition
that occurs when a
milk duct beneath the nipple dilates and its walls grow thicker, and the duct
fills with fluid. The milk duct can get blocked or clogged with a thick, sticky
substance. The condition may result in nipple discharge, breast tenderness or
inflammation of the clogged duct (periductal mastitis). This is a
benign and common finding in the developing breast. The patient may present
with nipple discharge that may be bloody or dark brown in nature, or a mass, or
both. It is often recommended to do an ultrasound of the affected breast to
make sure of the diagnosis and for reassurance.

3-  Hyperprolactinemia, or
elevated prolactin (the hormone that induces breast milk production) can cause
galactorrhea (milk leakage from the breast) in adolescents. If this is
suspected based upon detailed history and physical examination, lab tests and
imaging studies should be ordered in the evaluation process. Treatment is determined
according to the results of the history, physical examination, and laboratory
studies. If the culprit is a drug, it should be discontinued. A likely cause is
hypothyroidism (poorly active thyroid gland) and treating it would stop the
nipple oozing. Hyperprolactenemia can also be due to a benign tumor in the
pituitary gland (the gland that produces prolactin); this case is managed
medically or surgically.
