Clinically, the presence of breast enlargement can be detected through visual examination, palpation and symptoms. 1. Visual diagnosis: Observe the shape of your breasts with your hands hanging down. The main aspects to be observed include whether there is symmetry between the two sides of the breasts, whether there is any abnormal bulge, and whether there is any indentation on the skin surface. 2. Palpation: Hold the breasts with one hand underneath and touch the breasts with the other hand, and observe whether there are hard lumps in the breast tissues according to the order of outer upper, outer lower, inner lower and inner upper. 3. Clinical symptoms: Usually, it is necessary to observe whether there is any breast pain or lactation before the onset of menstruation. Other methods of self-testing for breast enlargement may exist. If you suspect that you have breast enlargement, it is recommended that you go to the breast surgery department of the hospital as soon as possible and cooperate with the doctor to complete the relevant examinations.
