Understanding the Differences Between Breast Cysts and Breast Cancer

Breast health is a topic of great importance, often eclipsed by concerns about breast cancer. But breast health involves understanding more than just cancer.

Today, we’ll delve into the intriguing world of breast cysts, exploring what they are, why they occur, and how they differentiate from breast cancer.

What Exactly Are Breast Cysts?

Imagine a small balloon filled with water. That’s pretty much what a breast cyst is. These fluid-filled sacs can be as tiny as a pea or as large as an orange.

But unlike an air-filled balloon, a breast cyst is a product of our body’s complex systems, specifically the hormonal and body changes that women undergo.

The Different Faces of Breast Cysts

Breast cysts are not all alike. They come in various shapes and sizes and can be broadly classified into three categories: simple, complicated, and complex cysts.

  •   Simple Cysts: These cysts are essentially ‘water balloons’ within the breast. They may feel like a lump, leading many to worry about a possible tumor. However, a mammogram or ultrasound reveals a straightforward structure, devoid of solid components—just fluid.

    If a simple cyst is small and painless, it may not require any intervention. But if it causes discomfort or shows a thick collection of fluid, fine needle aspiration can drain the fluid for relief.

    The drained fluid, especially if red or brown, is often sent for laboratory analysis. Recurrence may call for further evaluation with an ultrasound. The chances of cancer in simple cysts are negligible.

  •   Complicated Cysts: These cysts are similar to simple cysts but have some debris mixed with the fluid. This can occur due to various reasons, including infection. If you feel a lump and visit a physician, they may recommend an ultrasound followed by fine needle aspiration, if necessary.

    The aspirated fluid is sent for lab testing. If the fluid resembles pus, it might indicate an infection, warranting appropriate treatment. If bloody, it might require cancer screening.

  •   Complex Cysts: These cysts contain both liquid and solid components, with a thicker wall. In such situations, it’s crucial to evaluate the cyst, especially if it has a solid component

    An ultrasound and a core needle biopsy are usually recommended for a definitive diagnosis. If cancer is confirmed, a treatment plan is made accordingly. If not, observation is often the course of action.
