What are Breast Cysts?

Breast cysts are fluid-filled sacs that can develop in the breast tissue. They are usually noncancerous (benign) and can vary in size, ranging from a few millimeters to several centimeters [2][4]. Some cysts may be too small to feel, while others can grow large enough to cause discomfort or pain [3].

Characteristics of Breast Cysts

• Typically oval or round in shape
• Can develop quickly anywhere in the breast
• May be painful or uncomfortable
• Fluid-filled sacs that produce fluid from their lining, which fills up the space [5]

Types and Causes of Breast Cysts

Breast cysts are a common cause of breast masses or symptoms in general. They can occur at any age but are more common in women between 35 to 50 years old [7]. Fibrocystic disease of the breast is a larger benign disease process that includes breast cysts [8].

Symptoms and Treatment

A firm, round lump in breast tissue could be a fluid-filled cyst. Typically not cancerous, breast cysts often need no treatment [15]. However, it's essential to consult a doctor for proper diagnosis and advice.

Common Signs and Symptoms of Breast Cysts

Breast cysts are fluid-filled lumps that can develop in the breast tissue, and they can cause a range of symptoms. Here are some common signs and symptoms to look out for:

• Soft or firm lump: A breast cyst can feel like a soft or hard lump in the breast, with most being soft (1).
• Round and smooth shape: Cysts are typically oval or round and can develop quickly anywhere in the breast tissue (2).
• Painful or tender: Breast cysts can be painful or tender, especially before your menstrual cycle (3).
• Nipple discharge: Some women may experience nipple discharge with a breast cyst (3).
• Diffuse pain: Women with this condition report diffuse pain throughout their breasts and multiple small bumps scattered throughout the tissue (4).
• Round, smooth, and firm lump: A breast cyst can feel like a round, smooth, and firm lump in the breast (5).
• Tender to touch: The breast area around a cyst may also feel tender or painful if pressed on (6).

Important Notes

• Most breast cysts develop rapidly and then stay the same size (7).
• Breast cysts are usually not cancerous, but it's essential to consult a doctor for proper diagnosis and treatment.

Diagnosing Breast Cysts: A Comprehensive Overview

Breast cysts are fluid-filled sacs that can develop in the breasts, and diagnosing them requires a combination of physical examination, imaging tests, and possibly a biopsy. Here's an overview of the diagnostic tests used to identify breast cysts:

• Physical Examination: A healthcare provider may perform a physical exam to feel the consistency of the breast lump or cyst. This can help determine if it is a solid mass or a fluid-filled sac [1].
• Breast Ultrasound: An ultrasound test uses sound waves to create images of the breast tissue. It is often used as the first imaging test for breast lumps, including cysts [5]. Ultrasound can help distinguish between a cyst and other types of breast masses.
• Mammogram: A mammogram is an X-ray image of the breast that can help identify cysts, especially if they are large or complex. However, it may not be as effective for smaller cysts [6].
• MRI (Magnetic Resonance Imaging): MRI can be helpful in evaluating breast lumps that are not visible with mammography or ultrasound. It is particularly useful for women with dense breast tissue [4].
• Core Needle Biopsy: If a cyst is suspected, but the diagnosis is unclear, a core needle biopsy may be performed to collect tissue samples for further examination [9].

Additional Tests and Considerations

In some cases, additional tests or procedures may be necessary to confirm the diagnosis of a breast cyst. These can include:

• Diagnostic Mammogram: A diagnostic mammogram may be ordered if the initial mammogram is inconclusive or if there are concerns about the presence of cancer [6].
• Breast Biopsy: If a biopsy is performed, it can provide histology for an accurate diagnosis and allow immunohistochemistry (IHC) to determine the type of cells present in the breast lump [9].

Breast Cyst Drug Treatment

Breast cysts are benign (non-cancerous) lumps that can occur in women, especially those aged 35 to 50 years [7]. While most breast cysts resolve on their own, some may require medical treatment. Here are some common drug treatments for breast cysts:

• Pain relief medications: Over-the-counter (OTC) pain medications like acetaminophen (Tylenol), naproxen, or ibuprofen can help manage pain caused by breast oil cysts [8].
• Hormone therapy: In some cases, hormone therapy may be recommended to treat breast cysts. This can include birth control pills or other hormone therapies such as tamoxifen [5]. However, these medications are usually reserved for more severe cases and may have significant side effects.
• Tamoxifen: Tamoxifen is a medication that can be used to treat more advanced hormone-positive breast cancers, especially in post-menopausal women [9]. It may also be prescribed for breast cysts that persist despite other treatments.

It's essential to note that while these medications can help manage symptoms or treat underlying conditions, they should only be used under the guidance of a healthcare professional. If you're experiencing persistent or severe symptoms, consult with your doctor for proper diagnosis and treatment.

Differential Diagnosis of Breast Cysts

Breast cysts are fluid-filled sacs that develop in the breast tissue, and their differential diagnosis involves considering various conditions that may present similarly. Here are some possible differential diagnoses for breast cysts:

• Benign breast disease: Fibroadenomas and cysts are two common types of benign breast lumps that can be mistaken for breast cysts.
• Galactocele: A galactocele is a milk-filled cyst that can develop in lactating women, which may be confused with a breast cyst.
• Hematoma: A hematoma is a collection of blood that can form in the breast tissue, which may present as a cystic mass.
• Oil cyst: An oil cyst is a rare type of benign breast tumor that can be mistaken for a breast cyst.

According to [1], the differential diagnosis for a simple cyst includes galactocele, hematoma, and oil cyst. Additionally, [3] notes that breast cysts may fluctuate in size, which can make their diagnosis challenging.

In terms of imaging characteristics, [4] suggests that complicated cysts have internal low-level echoes, while complex cysts have both anechoic (cystic) and echogenic (solid) components. This information is crucial for radiologists to accurately diagnose breast cysts.

It's worth noting that the diagnosis of breast cysts often involves a combination of clinical evaluation, imaging studies, and histopathological examination. A thorough understanding of these differential diagnoses is essential for healthcare providers to provide accurate diagnoses and treatment plans.
