Breast cysts are a common concern for many women, often raising questions and worries when discovered. While these fluid-filled sacs are usually benign, understanding what causes them, how they’re diagnosed, and the treatment options available can provide clarity and peace of mind. At Bedford Breast Center, we specialize in comprehensive breast health care, including advanced diagnostics and solutions to address concerns with precision and care.

What Are Breast Cysts?

Breast cysts are fluid-filled sacs that form within the breast tissue. They can range in size from microscopic to a few inches across and may feel tender or even painful, especially before menstruation. Breast cysts are often described as round or oval lumps with smooth edges, similar to grapes or water balloons.

While breast cysts are typically noncancerous, their presence can still be unsettling, making an accurate diagnosis essential.

What Causes Breast Cysts?

Breast cyst causes can vary, but hormonal fluctuations, particularly changes in estrogen levels, play a significant role. Other contributing factors include genetics, age, and certain lifestyle factors.

Understanding the root cause can help determine whether treatment is necessary and guide you toward effective management options.

Types of Breast Cysts

Not all breast cysts are the same, and knowing the difference can help you better understand your diagnosis. Here are the main types of breast cysts:

  • Simple cysts are fluid-filled sacs with thin walls and smooth borders. These cysts are always benign (noncancerous). About 90% of cysts fit this category.
  • Complicated cysts may have irregular borders or cloudy fluid. They have a less than 2% risk of cancer.
  • Complex cysts contain both fluid and solid components. They are more likely to be cancerous (about 20%, or 1 in 5 cases) and typically require further evaluation.

Bedford Breast Center’s specialists can determine your type of cyst and the appropriate next steps.

How Are They Diagnosed?

An accurate diagnosis begins with a physical exam and imaging tests, such as breast ultrasound. This noninvasive test uses sound waves to create images of the breast tissue, determining whether a lump is fluid-filled (a cyst) or solid (potentially requiring further evaluation).

Depending on the cyst’s characteristics, additional diagnostic tools may include mammograms or biopsies. Regular screenings at a trusted facility like Bedford Breast Center can detect and address issues early.

Treatment Options for Breast Cysts

The treatment for breast cysts depends on their size, type, and whether they cause discomfort. For many simple cysts, no treatment is necessary, as they often resolve on their own. However, we may recommend removal if a cyst is causing pain or impacting your quality of life.

At Bedford Breast Center, we offer a groundbreaking solution called MILR (Minimally Invasive Lump Removal). This innovative procedure uses a small needle or probe guided by ultrasound imaging to remove cysts or other benign lumps without surgery. Benefits of MILR include:

  • Minimal downtime and quick recovery
  • Preservation of breast aesthetics
  • No visible scarring

If you’re considering breast cyst treatment, MILR may offer a safe and effective alternative to traditional surgery.
