The short explanation
A lump is the best-known sign, but breast cancer can also show up in other ways. Changes worth reporting include a change in the size or shape of one breast; dimpling, puckering or skin that looks like orange peel; redness or a rash on the breast or nipple; a nipple that has newly turned inwards; fluid or blood from the nipple without squeezing; and swelling or a lump in the armpit. Most breast changes, including many lumps, turn out to be harmless, such as cysts or fibroadenomas, especially in younger women. The goal is not to worry over every change, but to know what your breasts normally look and feel like, so you notice something new.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Breasts change across the menstrual cycle, often feeling lumpier or tender before periods. Checking at the same time each month, after your period, can make changes easier to spot.
- A family history of breast or ovarian cancer raises risk, and may mean starting screening earlier.
- There is no single right way to check. Looking in the mirror and feeling your breasts while bathing are both useful.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether any change you notice is serious. A doctor's examination and sometimes imaging are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Can you show me how to check my breasts?
- Which changes should make me come back quickly?
- Does my family history mean I need screening earlier?
- At what age should I start mammograms?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Get help the same day
- Get care the same day if a breast becomes hot, red, swollen and painful with fever.
Book an appointment soon
- See a doctor within a week or two for any new lump, skin change, nipple change or discharge that does not settle after your period.
Raise it at a routine appointment
- Ask at your next routine visit how to do breast self-checks.
