The hypervascularization of the pregnant breast and the role of
hormones during pregnancy and lactation have been incriminated
for the delays in diagnosis of breast cancer. A 38-year-old
multiparous patient (H.K.), G3P1, was admitted to our clinic to
evaluate her inability to walk, paresthesia in her legs, and fecal
and urine incontinence. According to obstetric ultrasonography
(USG), she was at 33-34 weeks of gestation. Because of fetal
distress, we performed cesarean section, and she delivered a
1850 g male baby with meconium. Postoperatively, she had prerenal
failure and hypercalcemia. Following our investigations, we
determined metastatic lesions in the cranium, liver, and sacroiliac
and vertebral bones. Unfortunately, when we diagnosed her
breast cancer, it was inoperable. We wanted to present our case
to discuss how diagnosis can be challenging in a pregnant woman
and to emphasize the dramatic and severe prognosis of breast
cancer during pregnancy because of the delay in diagnosis.
