Choose the right time
Once a month, a few days after your period ends, when the breasts are less tender. After menopause: the same day each month.
Look, arms by your sides
In front of a mirror, look at the shape, size, skin and nipples of both breasts.
Look, arms raised
Raise your arms above your head. Look for a dimple, a dip, orange-peel skin or a nipple turning inwards.
Hands on hips
Press firmly on your hips to tighten your chest muscles, and look again.
Feel with three fingers
With the opposite hand, flat, use the pads of three fingers. Make small circles, pressing lightly, then medium, then firmly.
The whole breast, including the armpit
Cover the whole breast in a spiral or in strips, from the collarbone to the bottom of the breast and up to the armpit.
Lying down too
Repeat lying on your back, with a small cushion under the shoulder on the side you are checking.
A change? See a doctor
Lump, dip, change in skin or nipple, discharge: show it to a doctor or midwife without waiting.
