Final answer:
The primary risk of hydatidiform mole is the development of choriocarcinoma, a type of cancer. Hydatidiform moles require careful medical follow-up due to this risk.
Step-by-step explanation:
The primary risk of a hydatidiform mole is A. Choriocarcinoma development. A hydatidiform mole, also known as a molar pregnancy, is a rare complication of pregnancy characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta. While most moles are benign, a hydatidiform mole can sometimes lead to the development of choriocarcinoma, a type of cancer that can occur in the uterus.
Hydatidiform moles are part of a group of diseases known as gestational trophoblastic disease (GTD), which also includes invasive moles, choriocarcinoma, and placental-site trophoblastic tumors. Among the risks, choriocarcinoma is particularly concerning because it has the potential to be malignant and can spread to other parts of the body.
It is important for patients diagnosed with a hydatidiform mole to receive proper medical follow-up, as early detection and treatment of choriocarcinoma can significantly improve the prognosis.
