A round lump can be felt in the breast when pinched, but it is not painful.
If a round lump is felt in the breast and it is not painful, it may be a sign of mammary gland hyperplasia. The detailed analysis is as follows:
Mammary gland hyperplasia is a common breast condition, mostly occurring in women aged 20 to 40. There are various causes of mammary gland hyperplasia, including endocrine disorders, unhealthy lifestyle habits, and mental stress. Common symptoms include breast lumps, breast pain, and nipple discharge; however, pain is not always present. Mammary gland hyperplasia is a benign condition and generally does not lead to serious consequences. However, if left untreated, it may develop into conditions such as mastitis or fibroadenoma. If a round lump is detected in the breast, women are advised to seek medical attention promptly for necessary examinations and treatment. Doctors will determine an appropriate treatment plan based on the individual patient's condition, which may include surgical intervention, traditional Chinese medicine therapy, or other approaches.
In addition, women should pay attention to breast health and hygiene in daily life—avoid wearing overly tight undergarments, refrain from prolonged bra use, and maintain a positive and relaxed mood. These practices can help prevent the development of mammary gland hyperplasia.
