Breast Cysts: Causes and Treatments
Breast cysts are fluid-filled sacs within the breast tissue, often causing anxiety due to their association with breast cancer. However, they are typically benign.
Breast cysts are common in women and can occur at any age but are most prevalent in those between 30 and 50 years old. They are usually round or oval, with distinct edges, and can vary in size. While some cysts are too small to feel, others can be several centimeters in diameter. They may feel like a soft grape or a water-filled balloon and can be either tender or painful.
Types of Breast Cysts
Breast cysts are categorized based on their size and the content of the fluid inside them:
- Microcysts: These are too small to be felt manually but can be detected through imaging tests.
- Macrocysts: These are larger, ranging from 1 to 2 inches, and can be felt easily. Macrocysts can cause discomfort due to the pressure they exert on surrounding breast tissue.

Get A Second OpinionCauses of Breast Cysts
The exact cause of breast cysts is not completely understood, but they may develop as a result of hormonal fluctuations, particularly during the menstrual cycle. Estrogen, a hormone that stimulates breast tissue, is thought to play a significant role. Other potential causes include:
- Breast tissue changes: As women age, their breast tissue can change, leading to the formation of cysts.
- Blockage in the milk ducts: This can lead to the accumulation of fluid, forming a cyst.
Symptoms of Breast Cysts
Breast cysts can present various symptoms, some of which include:
- A palpable lump in the breast that is movable and has smooth edges.
- Breast pain or tenderness in the area of the cyst.
- Changes in breast size or shape.
- Clear or colored nipple discharge.
While these symptoms can be alarming, it's important to note that breast cysts are usually benign. However, any new or unusual breast changes should be evaluated by a healthcare professional to rule out other conditions, including breast cancer.
Diagnosing Breast Cysts
When a breast lump is detected, a series of diagnostic tests may be conducted to confirm whether it is a cyst and to rule out malignancy:
Clinical Breast Exam
A healthcare provider will manually examine the breasts to assess the characteristics of the lump, such as its size, texture, and mobility.
Imaging Tests
- Mammogram: An X-ray of the breast used to screen for abnormalities.
- Ultrasound: This test uses sound waves to distinguish between solid masses and fluid-filled cysts.
Fine-Needle Aspiration
In this procedure, a thin needle is inserted into the cyst to withdraw fluid, which can confirm the diagnosis. If the fluid is clear and the lump disappears, it is likely a simple cyst. If the fluid is bloody or the lump doesn't resolve, further investigation may be necessary.
Breast Cysts Treatment
Most breast cysts do not require treatment unless they cause discomfort or persist over time. Treatment options include:
Monitoring
For cysts that are asymptomatic, regular monitoring may be sufficient. This involves periodic clinical exams and imaging tests to ensure there are no significant changes.
Aspiration
If a cyst is painful or large, fluid aspiration can alleviate symptoms. This procedure is minimally invasive and can be performed in a doctor's office.
Hormonal Therapy
In some cases, hormonal medications such as birth control pills may be prescribed to regulate the menstrual cycle and reduce the recurrence of cysts.
Surgery
Surgical removal is rarely necessary but may be considered if a cyst is recurrent, symptomatic, or has atypical features.
