The walkthrough

1
Time it right
For people with menstrual cycles, the best time is a few days after your period starts (around cycle day 5-7) — breast tissue is less lumpy and more uniform then. For post-menopause or irregular cycles, pick the same date each month.
2
Look in the mirror, arms at sides
Stand in front of a mirror with arms relaxed at your sides. Look for changes in size, shape, or symmetry; new dimpling or puckering of the skin; nipple changes (inversion, redness, scaling, discharge).
3
Then with arms raised
Raise your arms overhead. Look for the same changes — sometimes they're visible in this position when they weren't with arms down.
4
Examine each breast lying down
Lying down spreads the breast tissue thinly across the chest, making changes easier to feel. Use the pads of your three middle fingers (not fingertips), with light, medium, and firm pressure in turn.
5
Cover the whole area systematically
Use a vertical-strip pattern (up and down, like mowing a lawn) or concentric circles. Cover the area from the collarbone down to the bra line, and from the armpit across to the breastbone. Don't skip the armpit — lymph nodes there matter.
6
Stand up and repeat
Many people find lumps in the shower because soap and water make hands glide easily. Standing or sitting upright is the second pass — same systematic coverage.
7
What to look for
Most concerning: new lumps that feel different from surrounding tissue, especially hard, painless, or fixed in place. Also worth flagging: skin dimpling or puckering ("orange peel" texture), nipple inversion that's new, nipple discharge (especially bloody or one-sided), persistent skin redness or scaling. Most lumps are benign (cysts, fibroadenomas) — but anything new is worth a clinician visit.

BSE is part of awareness, not a substitute for screening. USPSTF gives BSE alone an "I" rating (insufficient evidence as a standalone screening tool), and modern guidance frames this as "breast self-AWARENESS" — knowing what's normal for your body so changes are obvious — paired with appropriate-for-age screening mammography. Most guidelines say start mammography screening between 40 and 50 depending on risk factors and shared decision-making with your provider. New lumps, skin changes, or nipple discharge get evaluated by a clinician regardless of screening interval.
