What is Breast Cyst?
Breast cysts are fluid-filled sacs that can develop within the breast tissue. Generally considered benign, these cysts are more common in women before menopause, typically under the age of 50, but can also occur in postmenopausal women who undergo hormone therapy. Understanding breast cysts—how they form, their symptoms, and the available treatment options—is essential for maintaining breast health.
Breast cysts feel similar to a grape or a water-filled balloon and may vary in firmness. These cysts can be classified based on their size:
Microcysts: These are very small and may only be detected through imaging tests like mammography or ultrasound. They are usually too tiny to be felt.
Macrocysts: Larger cysts that can be felt and may grow to about 1 to 2 inches (2.5 to 5 centimeters) in diameter.
Symptoms of Breast Cysts
Breast cysts can manifest in various ways, and it’s important to be aware of the signs:
Lump Characteristics: A breast cyst often presents as a smooth, movable lump with round or oval edges, which typically indicates a benign nature.
Nipple Discharge: You may notice discharge from the nipple that can be clear, yellow, straw-colored, or dark brown.
Breast Pain: Tenderness or pain in the area surrounding the cyst is common.
Menstrual Cycle Influence: You might observe an increase in lump size and breast tenderness just before your period, with a decrease in size and symptoms following menstruation.
While having breast cysts does not increase the risk of breast cancer, they can complicate the detection of new lumps or changes in breast tissue. It’s crucial to familiarize yourself with the normal feel of your breasts throughout your menstrual cycle to identify any changes promptly.
Causes of Breast Cysts
Breast tissue consists of lobes and lobules, which are responsible for milk production during pregnancy and breastfeeding. Cysts develop when fluid accumulates in the glands of the breast. While the exact cause of breast cyst formation is not well understood, hormonal fluctuations during the menstrual cycle are believed to play a significant role.
When to See a Doctor
While many breast cysts are harmless, it’s essential to be vigilant. You should consult a healthcare provider if you experience:
- A new breast lump that persists after one or two menstrual cycles
- A lump that increases in size
- New skin changes on one or both breasts
Your doctor may recommend further evaluation to rule out other conditions.
Diagnosis
Diagnosis typically involves a physical examination followed by imaging tests. Common diagnostic procedures include:
Mammography: This X-ray imaging technique helps visualize the internal structures of the breast, identifying any cysts or abnormalities.
Ultrasound: This imaging method uses sound waves to produce images of the breast tissue, allowing for a clearer view of cysts and distinguishing between solid masses and fluid-filled cysts.
In some cases, a healthcare provider may perform a fine needle aspiration (FNA) to extract fluid from a cyst for analysis. This procedure can also alleviate discomfort if the cyst is large.
Treatment Options for Breast Cysts
Most breast cysts do not require treatment unless they become large or cause significant discomfort. If intervention is necessary, options include:
Fluid Drainage: If a cyst is large and painful, draining the fluid can relieve symptoms. This procedure is often performed using a fine needle and can be done in a healthcare provider’s office.
Monitoring: If a cyst is asymptomatic and benign, it may simply be monitored over time to ensure it does not change or grow significantly.
Medications: In certain cases, medications may be prescribed to help manage pain or discomfort associated with breast cysts.
