Breast cancer is a public health problem.
One woman out of 11 has a risk of developing breast cancer over the course of her lifetime. This pathology is the first cause of death in women between 40 and 55 years old. The risk of breast cancer rises with age and a plateau of incidence is obtained around 70 years old. The aim of screening is the detection of an anomaly before any symptom. Several years can be lost before a breast cancer can be palpable.
