What is a Breast Cyst?
A breast cyst is a fluid-filled sac that forms in the breast tissue. They can vary in size, from very small to several centimeters in diameter. Breast cysts are quite common and often occur in women aged 30 to 50, particularly those going through hormonal changes. These cysts can be solitary or multiple, and they may be palpable as a lump in the breast or identified via imaging techniques such as mammograms or ultrasounds.
Symptoms
Breast cysts may feel smooth or firm, and they can change in size throughout the menstrual cycle due to hormonal fluctuations. Some women may experience discomfort or tenderness, but many cysts are asymptomatic and discovered incidentally during medical evaluations.
Causes
The exact cause of breast cysts is not entirely understood, but they are believed to result from changes in the normal breast structure, likely related to hormonal changes. Factors such as age, hormonal therapy, and previous breast conditions can also influence their development.
Diagnosis and Treatment
If a breast cyst is suspected, a healthcare provider may perform a physical exam and recommend imaging tests. In most cases, no treatment is necessary unless the cyst is painful or causes significant discomfort. If required, a cyst can be drained using a needle. Regular monitoring is advised to ensure there are no changes that warrant further investigation.
