[Desire for a child after breast cancer]

In France 10% of the new cases of breast carcinomas (more than 25,000) are less than 40 years old; we don't know exactly what is the opinion of these women about having children after such a diagnosis; medical adjuvant treatments, Gn Rh agonists and Tamoxifen or adjuvant chemotherapy can modulate temporarily or definitively fertility. Data on pregnancy in breast cancer survivors are limited and consist only of retrospective series: the prognosis doesn't seem to be influenced by subsequent pregnancy; in practice, when the risk of relapse is high (patients N+ or N- grade III) it's reasonable to wait for two or three years before pregnancy, and when the risk is quite low (microinvasive or T1 low grade N- tumor) no delay between carcinoma's treatment and pregnancy is necessary to preserve the good prognosis.
