[Breast cancer in pregnancy].

Breast cancer in pregnancy is a very rare condition. At present this doesn't seem a condition with a particularly grim prognosis. It's often only an underestimate of the mammalian masses in pregnancy which produces a delay in the diagnosis and the consequent grim prognosis. The authors recommend on the basis of their experience a careful control of mammalian masses in pregnancy and an opportune diagnosis that allows to operate as soon as possible. It's likewise underlined that interruption of the pregnancy don't seem to improve the prognosis.
