Although most are benign, if a malignancy complicates pregnancy, then usual management schemes become problematic. Uterine leiomyomas and ovarian cysts are the most frequently encountered benign neoplasms during pregnancy. Malignancies have an incidence of approximately 1 per 1000 pregnancies (Brewer, 2011). One third are diagnosed prenatally and the others within 12 months of delivery. Some of the more common cancers found in pregnant women are shown in Figure 63-1. Of these, the three most common are breast—1 per 5000 pregnancies, thyroid—1 per 7000, and cervical—1 per 8500 (Smith, 2003). These, along with lymphoma and melanoma, account for 65 percent of cancer cases in pregnancy (Eibye, 2013).
