A breast cyst is a benign formation that is a cavity filled with fluid. It can vary in size from a few millimeters to several centimeters. Patients often describe it as a “lump in the breast,” “ball in the breast,” or even “stone in the breast.” Although this condition is usually not dangerous, its presence requires observation by a breast specialist.
Unlike malignant tumors, a breast cyst has clear boundaries, a smooth surface, and may change in size during the menstrual cycle. If the cyst does not cause inflammation, it is painless on palpation. At the same time, some women may experience discomfort or even pain in the breast, especially before menstruation. It is important to differentiate a cyst from fibroadenoma, mastitis, and other breast pathologies.
There are several types of breast cysts:
- A simple cyst is a single-chamber formation containing fluid.
- Atypical cyst – has internal growths and requires more careful observation.
- Fat cyst – occurs as a result of blockage of the sebaceous glands and does not pose a cancer risk.
- Fibrocystic mastopathy – a condition in which multiple lumps form in the breast, associated with hormonal changes.
- Solitary cyst – a single benign formation.
- Ductal cyst – located in the milk ducts and may cause discomfort.
- Polycystic breast disease – characterized by the presence of a large number of small cysts in the breast tissue.
Usually, a cyst is discovered by chance during a self-examination or a preventive examination by a mammologist. It may feel like a “lump in the breast” or “thickening in the breast.” For an accurate diagnosis, the following are used:
- Ultrasound examination (US) – allows you to determine the size and structure of the cyst.
- Mammography – used to differentiate cysts from other formations.
- Puncture – necessary to determine the nature of the fluid inside the cyst.
The main cause of cysts is hormonal imbalance. Risk factors include:
- Hormonal disorders (excess estrogen, progesterone deficiency).
- Breast injuries.
- Inflammatory processes in the mammary gland.
- Genetic predisposition.
- Chronic stress.
- The influence of external factors, such as poor nutrition and bad habits.
A mammary gland cyst is a benign formation that forms as a result of blockage of the milk ducts and accumulation of fluid. It can manifest as a “lump in the mammary gland,” “ball in the mammary gland,” “stone in the breast,” or “lump on the breast.” The main causes of breast cysts are:
- Hormonal imbalance – the main risk factor, especially excess estrogen.
- Genetic predisposition – increased risk in women whose relatives have had similar problems.
- Mechanical trauma to the breast – blows or compression can contribute to the development of cysts.
- Inflammatory processes – mastitis or other infections can lead to changes in breast tissue.
- Poor diet – excessive consumption of fats, fast food, caffeine, and alcohol.
- Chronic stress – negatively affects hormonal balance and can contribute to the formation of lumps in the breast.
Breast cysts vary in size, ranging from a few millimeters to several centimeters. Cysts measuring 2 cm or more are considered large. They can cause discomfort, pain, and even changes in the shape of the breast. In such cases, additional observation or treatment may be necessary, including puncture or sclerotherapy.
A cyst in the breast does not usually cause pain unless it reaches a significant size or becomes inflamed. However, some women report:
- Increased sensitivity of the breasts before menstruation.
- A feeling of fullness in the area of the breast lump.
- Discomfort when palpating the cyst.
If the cyst causes severe pain or begins to grow rapidly, you should immediately consult a mammologist.
Polycystic breast disease is a condition in which several small cysts form in the breast. It is often associated with fibrocystic mastopathy and hormonal disorders. With multiple cysts, it is important to undergo regular examinations by a mammologist to rule out the risks of inflammatory processes or possible complications.
If you have been diagnosed with a mammary gland cyst, you must follow certain rules:
- Do not self-medicate – folk methods can only worsen the condition.
- Do not ignore regular check-ups – even if the cyst does not cause discomfort, it should be monitored.
- Do not warm your breasts – warming can provoke inflammation.
- Do not squeeze or massage the cyst – this can cause it to rupture or become infected.
- Do not take hormonal drugs without a doctor's prescription – self-medication with hormones can lead to an increase in the cyst.
To reduce the risk of cyst formation, follow these recommendations:
- Have regular check-ups with a mammologist – at least once a year.
- Eat a balanced diet – reduce your intake of caffeine, fatty foods, and alcohol.
- Be physically active – this improves hormonal balance and blood circulation.
- Avoid stress – your psychological state directly affects the health of your mammary glands.
- Wear the right underwear – your bra should support your breasts without constricting them.

Why do breast cysts change in size during the menstrual cycle?
Hormonal fluctuations of estrogen and progesterone affect fluid accumulation in the breast ducts. As a result, the cyst may temporarily enlarge before menstruation and shrink afterward. For an accurate assessment, doctors recommend performing a breast ultrasound during a specific phase of the cycle.
-
How can you tell if a breast lump requires immediate medical attention?
If a lump does not disappear within a few weeks, is accompanied by pain, changes in breast shape, redness, or nipple discharge, it is a significant reason not to delay. In such cases, an urgent consultation with a mammologist is necessary to determine the next steps in examination.
-
Why is a puncture necessary for some cysts?
A puncture allows examination of the cyst’s contents, exclusion of atypical cells, and, if necessary, reduction of the cyst’s size. The procedure is performed for medical indications after a doctor’s examination. The specialist determines its necessity during a mammologist or oncologist consultation.
-
How do multiple cysts differ from a single cyst?
Polycystic changes are usually associated with systemic hormonal disorders and require more regular monitoring.
-
What external factors can accelerate cyst formation?
Breast trauma, chronic stress, excessive caffeine consumption, and an unbalanced diet can affect breast tissue condition.
-
Why are heating and breast massage considered dangerous for cysts?
Heat and mechanical pressure can cause inflammation or complications in the area of the cyst.
-
How do regular preventive examinations affect prognosis?
Early detection of changes allows monitoring of breast health without radical interventions and helps maintain long-term wellness.
