Is one breast larger than the other a sign of breast cancer?

One breast is larger than the other, which may be caused by breast cancer, or it may not be caused by breast cancer, but by other factors, such as congenital factors, lactation, breast hyperplasia, etc. The cause cannot be judged simply based on the size of the breasts. You need to go to the hospital for treatment and conduct relevant examinations to determine the cause and then take targeted measures. The specific analysis is as follows:

1. It may be breast cancer

For breast cancer patients, the tumor grows in the breast, which may cause changes in breast size and shape. After one breast is diagnosed with breast cancer, the size and shape of the breast may change, and it may also be accompanied by breast skin depression, bloody nipple discharge, and enlarged lymph nodes under the armpit. After breast cancer is confirmed, surgical treatment is generally required, and if necessary, chemotherapy, endocrine therapy, targeted therapy, etc.

2. Not Breast Cancer

1. Congenital factors: Since each woman has different genes, the breasts on both sides may be of different sizes during the development process, but the normal physiological structure of the breasts on both sides is the same, and no special treatment is needed.

2. Lactation: Some babies always eat from one breast when breastfeeding, which causes milk congestion and swelling in the other breast, resulting in symptom of different breast sizes. This is not cancer, and correcting the bad feeding method can improve the symptoms, and no other treatment is needed.

3. Breast hyperplasia: Due to the imbalance of estrogen and progesterone ratio, taking contraceptives, eating habits, etc., the normal structure of the breast may be disrupted, causing patients to experience symptoms such as breast pain, nodules or lumps, but this is a common benign breast disease. For those with mild symptoms, temporary observation without treatment is recommended. For those with more severe symptoms, it is recommended to give medication under the guidance of a doctor, such as Rupixiao Tablets, Xiaoyao Pills, Xiaojin Pills, etc.

In addition to the above reasons, breast fibroadenoma can also cause this symptom. It is recommended that patients seek medical attention and undergo relevant examinations in a timely manner to check.
