When is the Best Time to Check Your Breasts?
Breast health Breast Cancer
If you still have periods, the best time to check your breasts is three to five days after your period starts, when breasts are less tender and lumpy. If you no longer have periods, pick a memorable day each month, like the 1st. Checking your breasts monthly, at the same time each cycle, helps you learn what's normal for you and catch changes early—many breast cancers are first found by women themselves.

Frequently asked questions
When should I do a breast self-exam if I still have periods?
Check three to five days after your period begins. At this point, hormonal fluctuations have settled and your breasts are less tender and lumpy, making it easier to notice real changes.
When should I check if I've gone through menopause?
Choose a consistent day each month that's easy to remember, such as the first day of the month, and stick with it.
Why does timing matter for a breast self-exam?
Breast tissue changes throughout your menstrual cycle. Checking at the same time each month, when breasts are least tender, helps you accurately track what's normal and notice genuine changes.
How often should I do a breast self-exam?
Once a month is recommended. Regular checks help you become familiar with your breasts so you can quickly identify anything unusual.
What's the first step in a breast self-exam?
Stand upright with your hands on your hips and visually inspect your breasts using a mirror, phone camera, or a friend's help.
What visual changes should I look for?
Look for changes in size, shape, or colour, swelling, or dimpling and puckering of the skin. Check again with your arms raised.
How do I feel for lumps correctly?
Use the flat pads of your fingers, moving in small circles across your breast. Apply light, then medium, then firm pressure—firm enough to feel your ribcage.
Do I need to check my armpit too?
Yes. Extend your exam all the way up to the armpit area, using your left hand for the right breast and vice versa.
Should I check my nipples?
Yes, gently squeeze each nipple to check for any unusual discharge.
Is it helpful to check breasts lying down or in the shower?
Yes. Lying down spreads the breast tissue evenly, and checking in the shower—when skin is wet and soapy—can make it easier to feel changes.
What should I do if I find a lump?
Don't panic—many lumps are harmless and can fluctuate with your menstrual cycle. However, if a new lump doesn't go away after one month or seems to be growing, speak to a healthcare provider.
Why is monthly self-checking so important?
The more familiar you are with your breasts, the easier it is to notice when something changes. Since many cancers are first found by women themselves, regular self-exams play a key role in early detection.
