Dr. Yang Wangjun reply Obstetrics and Gynecology


Hello: (1) If there is a hard lump in the breast, a detailed examination is necessary.
You should see a breast surgeon for a breast ultrasound, mammogram, or MRI.
If needed, a biopsy may be performed to confirm the diagnosis.
(2) During the luteal phase before menstruation, progesterone levels increase, causing breast engorgement and tenderness as the body prepares for potential pregnancy and lactation.
If pregnancy does not occur, progesterone levels decrease, and the breast discomfort will subside, which is a normal physiological process.
(3) If it is a tumor, it will not disappear after childbirth.
Thank you for your message!

Understanding breast lumps after puberty can be a source of concern for many individuals, especially when it comes to distinguishing between normal physiological changes and potential health issues. Let's address your questions one by one, providing clarity on what you might be experiencing.

Question 1: Is it normal to have small lumps in the breast after puberty?
Yes, it is quite common for individuals to have small lumps in their breasts after puberty. These lumps are often benign and can be attributed to normal breast tissue changes. The breast is composed of glandular tissue, connective tissue, and fat, and during puberty, hormonal changes can lead to the development of fibrocystic changes, which are characterized by the presence of small, non-cancerous lumps. These lumps may feel like small hard nodules and can vary in size and tenderness. If the lumps are not painful and have been stable over time, they are likely benign. However, it is always advisable to have any new or changing lumps evaluated by a healthcare professional to rule out any potential issues.

Question 2: Is it normal for breasts to swell and become painful before menstruation?
Yes, experiencing breast tenderness, swelling, and the sensation of lumps before menstruation is a common symptom known as cyclical mastalgia. This condition is linked to hormonal fluctuations that occur during the menstrual cycle. Estrogen and progesterone levels rise and fall, leading to changes in breast tissue that can cause swelling and discomfort. Many individuals report that their breasts feel fuller or more sensitive in the week leading up to their period, and this typically resolves once menstruation begins. If the pain is severe or accompanied by other concerning symptoms, it is important to consult a healthcare provider.

Question 3: Will small lumps disappear after childbirth?
In many cases, small lumps in the breast may change after childbirth due to hormonal shifts associated with pregnancy and breastfeeding. During pregnancy, the breasts undergo significant changes in preparation for lactation, which can lead to the development of new lumps or changes in existing ones. After breastfeeding, some individuals may notice that certain lumps diminish or resolve entirely, while others may remain. It is important to monitor any changes in the breast and consult with a healthcare provider if you have concerns about persistent lumps or any new symptoms.

Additional Considerations:
While many breast lumps are benign, it is crucial to remain vigilant about breast health. Regular self-examinations and clinical breast exams are essential for early detection of any changes. If you notice any new lumps, changes in size or shape, or if you experience unusual discharge from the nipples, it is important to seek medical advice promptly.

In summary, having small lumps in the breast after puberty is often normal and can be attributed to benign conditions such as fibrocystic changes. Breast tenderness and swelling before menstruation are also common due to hormonal fluctuations. Changes in breast tissue may occur after childbirth, but it is essential to monitor any persistent lumps and consult with a healthcare provider for personalized advice and evaluation. Regular check-ups and awareness of your breast health are key to ensuring any potential issues are addressed early.
