Introduction: The pregnancy-associated breast cancer seems to have become increasingly common with a high frequency of advanced breast cancer with axillary node metastases and so associated with poor prognosis.
Materials and methods: This review examines the diagnosis, prognosis, and management of cancer during pregnancy; both in terms of the cancer's effect on the pregnancy, and the pregnancy's effect on the cancer.
Results: Diagnostic procedures (breast sonography) and excisional biopsies are necessary to reduce the delay of several months or more after discovery of a mass and before treatment. No histological difference, between patients with pregnancy-associated breast cancer and patients with non-pregnancy-associated breast cancer, was diagnosed.
Conclusion: The treatment is linked to the effects of adjuvant therapy on the fetus.
