About 1 in 8 women in the UK are diagnosed with breast cancer during their lifetime. If it's detected early, treatment is more successful and there's a good chance of recovery.
Breast screening uses an X-ray test called a mammogram that can spot cancers when they're too small to see or feel.
Breast screening is offered to women aged 50 to their 71st birthday in England. You'll first be invited for screening within three years of your 50th birthday.
