Introduction
In general, cysts during lactation may be caused by hormonal changes, breast tissue injury, breast duct dilation, blocked milk ducts, bacterial infection, or other factors. Patients are advised to seek timely medical attention to avoid adverse outcomes. 1. Hormonal changes: Lactation cysts refer to fluid-filled or sac-like structures that form within the breast tissue during breastfeeding.
Under normal circumstances, cysts during lactation may be caused by hormonal changes, breast tissue injury, mammary duct dilation, blocked milk ducts, bacterial infection, or other factors. Patients are advised to seek timely medical attention to prevent adverse outcomes. The specific analysis is as follows:
1. Hormonal changes: Lactation cysts refer to fluid-filled or sac-like structures that form in the breast tissue during breastfeeding. During this period, hormonal levels in women fluctuate, which may lead to breast tissue proliferation and milk accumulation, resulting in cyst formation. This is considered a normal phenomenon and typically resolves on its own after weaning, requiring no special treatment.
2. Breast tissue injury: Trauma to the breast tissue—such as impact or compression—may cause fluid accumulation within the breast, leading to cyst formation. It is important to avoid pressure on the area; massage may help relieve symptoms.
3. Mammary duct dilation: During lactation, the mammary ducts expand to transport milk. Excessive milk accumulation under such conditions may result in cyst formation. If milk supply is abundant, expressing some milk regularly can help alleviate the cyst.
4. Blocked milk ducts: Duct obstruction is one of the most common causes of lactation cysts. When a milk duct becomes blocked, milk cannot drain properly, causing fluid buildup in the breast tissue and forming a cyst. For mild blockages, massaging the breasts before breastfeeding or pumping may help open the obstructed duct.
5. Bacterial infection: Breast tissue infection is another common cause of lactation cysts. Bacterial infection can trigger inflammation and swelling in the breast tissue, leading to cyst development. Treatment may include oral antibiotics such as roxithromycin capsules or cefixime capsules, as prescribed by a physician. However, breastfeeding should be avoided during medication use to prevent potential adverse effects in the infant.
It should be noted that breast cysts are usually benign. However, if the cyst causes severe pain, fever, redness, or swelling, or if it persists and continues to grow, prompt medical evaluation and treatment are recommended.
