Final answer:
Regular monitoring for cancer, including abdominal ultrasounds and blood tests for tumor markers like AFP, is necessary for patients with hemihypertrophy due to the increased risk of malignancies.
Step-by-step explanation:
Patients with hemihypertrophy are at an increased risk for certain types of cancers, such as Wilms tumor, hepatoblastoma, and adrenocortical carcinoma. Therefore, regular monitoring for cancer is essential in these patients. A healthcare professional performing blood pressure monitoring, as depicted, one aspect of the overall surveillance strategy. Due to the increased risk of malignancy, additional tests may include abdominal ultrasounds, MRIs, or blood tests that check for tumor markers like alpha-fetoprotein (AFP) which can suggest a relapse or the presence of a tumor. For instance, in a child previously treated for teratoma, elevated AFP levels can indicate a relapse with endodermal sinus tumor. The specific type of treatment recommended by a doctor will depend on the individual case and may include surgery, chemotherapy, or radiation therapy if a malignancy is diagnosed.
