Dear Concerned About A Lump Under My Left Nipple,

TeenHealthFX can appreciate that you are feeling scared, but try not to worry too much about this small lump. Breast lumps in teenagers can be common and most often are not a sign of something malignant (cancerous). The following are possible causes of the lump:

  • A tender lump may be due to something called a cyst, a sac that is usually filled with fluid or semisolid material. Cysts can get smaller or larger with time. If the cyst does not go away on its own, your doctor may need to use a needle to drain it.

  • Hormones during puberty can also cause swelling of breast tissue, and some males that have a significant portion of breast tissue may have a condition called gynecomastia. Gynecomastia is also benign (non-cancerous), and will only need further management if causes anxiety or social concern. 

While this lump is probably not something to get too worried about, any new or painful lumps should be evaluated by your doctor. Your doctor will be able to assess whether or not the lump requires further testing. Your doctor can also evaluate for a cystic vs. a solid lesion using a test called an ultrasound.  Your doctor will ask you about any drainage from your nipple, if the lump has changed since you discovered it, and if there has been any redness or warmth over the region.  These questions will help your doctor to discover the underlying reason for the lump. 

In addition to meeting with your doctor, FX recommends that you continue to monitor and become familiar with your own body so that you can assess for changes like these.

If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist or contact your local teen health center or Planned Parenthood. You can also contact your insurance company for a list of in-network providers.
