In the Shower
With the pads/flats of your 3 middle fingers, check the entire breast and armpit area pressing down with light, medium, and firm pressure. Check both breasts each month feeling for any lump, thickening, hardened knot, or any other breast changes.
In the Mirror
Visually inspect your breasts with your arms at your sides. Next, raise your arms high overhead.
Look for any changes in the contour, any swelling, or dimpling of the skin, or changes in the nipples. Next, rest your palms on your hips and press firmly to flex your chest muscles. Left and right breasts will not exactly match — few women’s breasts do, so look for any dimpling, puckering, or changes, particularly on one side.
In the Bed
When lying down, the breast tissue spreads out evenly along the chest wall. Place a pillow under your right shoulder and your right arm behind your head. Using your left hand, move the pads of your fingers around your right breast gently covering the entire breast area and armpit.
Use light, medium, and firm pressure. Squeeze the nipple; check for discharge and lumps. Repeat these steps for your left breast.
