Doing a breast self breast exam once a month helps you stay familiar with how your breasts normally look and feel. That way, if something changes, you’ll be the first to notice and speak up.
Let’s Talk About the “Self-Exam”
The phrase self-exam can sound clinical, but think of it more like a monthly check-in with your boobs. According to the American Cancer Society, breast self-awareness is key — while clinical exams and mammograms are the gold standard for screening, noticing a new lump, dimple, or skin change between appointments can make a difference in early detection.
And here’s why it’s worth your time: breast cancer accounts for nearly 30% of all new cancers diagnosed in women in the U.S. According to the American College of Obstetricians and Gynecologists (ACOG), a woman’s lifetime risk of developing breast cancer is around 12%, or one in eight. That means awareness matters at every age — especially since you’re the one most likely to notice changes between appointments.
When and How to Do It (Without Spiraling)
While formal guidelines vary, many clinicians recommend doing a self-exam once a month, ideally a few days after your period ends when your breasts are least tender and swollen. If you’re not menstruating, pick the same day each month (set a recurring phone reminder — yes, like your plant watering alert).
Here’s the general game plan:
- Visual check: In front of a mirror, arms relaxed, then raised. Look for changes in size, shape, skin texture, or nipple position.
- Feel check (standing): Use the pads of your fingers in small circles, covering your whole breast and armpit area. Use light, medium, and firm pressure to feel all layers.
- Feel check (lying down): Same pattern as above, but gravity changes how tissue spreads, so you might notice different things.
What’s “Normal” Anyway?
Breasts naturally have lumps, ridges, and changing textures — especially if you’re breastfeeding, pumping, or recently weaned. Milk ducts, cysts, and hormonal changes can make things feel bumpy. What matters is noticing new changes:
- A lump that wasn’t there before
- Persistent swelling or redness
- Skin dimpling or puckering
- Nipple inversion (if it’s new for you)
- Discharge that isn’t milk
If you notice a change, don’t hesitate to reach out to your healthcare provider. ACOG encourages breast self-awareness and recommends talking to a clinician about anything that feels new or different. You don’t need to figure it out alone — just bring it up and let the pros take it from there.
The Real Talk
Checking in with your body is just one more way to take care of yourself. A few minutes once a month can give you peace of mind and help you catch changes early. You already know your body better than anyone — trust that, and speak up when something feels off.
