Step 1: stand in front of the mirror, hang your hands, and carefully observe whether the breasts are symmetrical and the appearance is normal;
Step 2, put one hand behind your head, press all parts of the breast with a finger pulp in a spiral way, check whether there is lymph gland mass under your armpit, and pat the nipple for secretion;
Step 3: Lie on your back in bed with a small pillow behind your head. Gently press the left breast with the fingers of your right hand and do a small circle massage. Check the rotation clockwise from twelve o'clock and massage for at least three times. Then check the breast with your left hand.
