Fibrocystic breast changes: Clinical sciences

Fibrocystic breast changes include a spectrum of benign breast changes characterized by multiple bilateral nodules within the breast tissue. This condition is most commonly found in females between the ages of 30 and 50 years. Although the exact etiology is not fully understood, a hormonal component, such as overproduction of estrogen and underproduction of progesterone is likely, especially since symptoms like breast pain, also known as mastalgia, tend to worsen in a cyclical pattern towards the end of the menstrual cycle.

Alright, now, when a patient presents with a chief concern suggesting fibrocystic breast changes, the first step is to obtain a focused history and perform a physical examination. The patient might report bilateral breast nodularity, pain, swelling, and possible straw-colored nipple discharge. These symptoms may worsen just prior to menstruation each month. On physical examination, you might find multiple nodular areas, a ropey and lumpy texture, and tenderness on palpation. At this point, you should suspect fibrocystic breast changes.

The next step is to order a breast imaging to confirm your diagnosis. Now, if your patient is younger than 35 years, order a breast ultrasound; but, if your patient is 35 years of age or older, you should obtain both a breast ultrasound and a mammogram.

Okay, let’s talk about the results. If there are no findings on imaging that would indicate fibrocystic breast changes, then you should consider an alternative diagnosis. On the other hand, ultrasound findings consistent with fibrocystic breast changes include fibroglandular tissue, clustered microcysts, distorted breast parenchyma, and an absence of discrete masses. As for the mammogram, it might show heterogeneous and dense breast parenchyma, partially circumscribed cysts, as well as crescent-shaped calcifications in multiple lobes. If you see these findings on imaging, then you are dealing with fibrocystic breast changes.

Alright, now that we diagnosed fibrocystic breast changes, let’s move on to management. Keep in mind that fibrocystic breast changes per se don't need to be treated; what’s actually treated are the symptoms of the disorder, such as mastalgia.
