The term ‘screening’ refers to tests and examinations used to find a disease (such as cancer) in people who do not have any symptoms. The goal is to find the disease early before it has a chance to spread. The size of the tumour and how far it has spread are the most important factors determining the final outcome for the patient.

Therefore, the early detection of breast cancer can be the key to survival or in other words, the earlier the cancer is found, the better the chances that treatment will work.

Breast self-examinations (BSE), clinical breast examinations (by a trained doctor or health care professional) and screening mammography are therefore important in detecting breast cancer at an early stage.
