Why self-examination matters
NHS screening only takes place every three years. Breast cancer can develop between appointments. Regular self-examination means you are more likely to notice a change early, when treatment is most effective.
The TLC method
- TOUCH: Using the flat of your fingers, gently feel your entire breast, armpit and collarbone area. Feel for any new lump, thickening or area that feels different from the rest. You can do this lying down, standing, or in the shower.
- LOOK: Stand in front of a mirror with your arms by your sides, then raised above your head. Look for any change in size, shape or contour; any skin changes (dimpling, puckering, redness, "orange peel" texture); any nipple changes (inversion, discharge, rash).
- CHECK: If you notice anything new or unusual, see your GP promptly — do not wait. Most changes are not cancer, but only a doctor can confirm this.
How often should you check?
There is no evidence that a strict monthly routine is necessary. The NHS recommends simply being "breast aware" — incorporating regular checking into your normal routine, for example in the shower or when getting dressed. Premenopausal women may find it easiest to check at the same point in their menstrual cycle each time, when breasts are least tender (usually a week after a period).
What is normal?
Most women's breasts are not identical. Some degree of lumpiness is normal, particularly in the week before a period. What you are looking for is anything NEW or CHANGED from what is normal for you. If in doubt, see your GP.
Breast changes to get checked
Changes can look different on different skin tones. Contact a GP, or your doctor if you live outside the UK, about any change that is new or unusual for you. Most changes are not cancer.
