It doesn't need to be anything complicated, just follow the five point code:

• Know what is normal for you


• Look and feel


• Know what changes to look for


• Report any changes without delay


• Attend breast screening if aged 50 or over

Changes to look for include:

• A lump or thickening which is different to the rest of the breast tissue


• Continuous pain in one part of the breast or armpit


• One breast becomes larger or lower


• A nipple becomes inverted or changes shape or position


• Skin changes including puckering or dimpling


• Swelling under the armpit or around the collarbone


• A rash on or around the nipple


• Discharge from one or both nipples
