Breast Cysts
Breast cysts are fluid-filled sacs in the breast tissue. They are very common, especially around perimenopause, and may feel like a soft or firm lump. Many cysts are harmless and resolve on their own, but some cause discomfort or appear suspicious on imaging.
At The Medical Group of New Jersey, we use targeted imaging and, when needed, in-office or image-guided aspiration to confirm the diagnosis and relieve symptoms.
Symptom Onset & Initial Evaluation
Breast cysts are fluid-filled sacs within breast tissue and are a common cause of breast lumps, particularly in women between the ages of 35 and 50. Many cysts are harmless and may change in size over time, often influenced by hormonal fluctuations.
Patients with breast cysts may notice symptoms such as:
- A round or smooth breast lump that may feel mobile under the skin
- Breast tenderness, which may become more noticeable before a menstrual period
- A feeling of fullness or localized swelling in one area of the breast
During your visit, your breast surgeon will review your symptoms and medical history, including the timing of breast changes, hormonal factors, and any prior history of cysts or breast imaging. The evaluation may also include questions about nipple discharge or other associated symptoms.
A focused breast examination is then performed to assess the lump and determine whether additional imaging is needed.
Diagnosis
When a breast cyst is suspected, imaging studies are used to confirm whether the lump contains fluid or represents a solid mass.
Diagnostic testing may include:
- Breast ultrasound, which is the most effective imaging test for distinguishing a fluid-filled cyst from a solid breast mass
- Diagnostic mammography, recommended in some patients, depending on age and imaging findings
- Needle aspiration, a simple procedure that removes fluid from the cyst when it is painful, large, recurrent, or unclear on imaging
If the aspirated fluid appears bloody or if the cyst returns quickly after drainage, further evaluation may be recommended to ensure no underlying abnormality is present.
Treatment & Ongoing Management
Treatment for breast cysts depends on the symptoms and imaging characteristics of the cyst. Management options may include:
- Observation and routine monitoring for simple cysts with reassuring imaging features
- Needle aspiration to relieve discomfort or confirm the diagnosis
- Surgical removal, which is rarely necessary but may be recommended for cysts that are recurrent, complex, or associated with suspicious imaging findings
Your breast surgeon will review the imaging results and discuss the most appropriate management strategy based on your symptoms and overall breast health.
Follow-Up Care
Follow-up care helps ensure that cysts remain stable and that any new breast changes are evaluated promptly.
Depending on the imaging findings, follow-up may include:
- Repeat breast imaging within a recommended time frame for complex or atypical cysts
- Clinical breast exams to monitor for new or changing breast lumps
With appropriate evaluation and monitoring, most breast cysts remain benign and do not require long-term treatment.
