Breast cancer has significant importance to public health. There is still no primary treatment of breast 
cancer, and early detection results tend to be the main priority in the fight against breast cancer. Breast 
cancers found during screening examinations are more likely to be smaller and still confined to the 
breast, with better prognosis than those detected late with extensive spread outside the breast tissue.

Screening refers to tests and examinations used to detect a disease in people with no symptoms. Early 
detection means finding a disease before it awaits its symptoms to appear. Unlike breast selfexamination and clinical examination, mammogram is the screening test which has been shown to 
reduce breast cancer mortality rate.
