A Large Bladder Tumor During Pregnancy: Twin Challenge

Abstract

Malignant tumors during pregnancy are a rarity with the overall incidence being approximately 2.35/10,000 (1) and the commonest are malignant melanomas (2.8/1,000), cervix (1/2,200), breast (1/3,000) and lymphomas (1/6,000) (2,3). Urological malignancies during pregnancy are extremely rare, affecting about 13 in 1,000,000 pregnancies (4). Common signs of urological malignancies especially bladder tumors such as hematuria, urgency, lower abdominal pain, may be attributed to the pregnancy. Combined with the hesitancy to undergo imaging, these overlapping symptoms may result in delayed diagnosis.
