This refers to return of a previously treated yolk sac tumor, a malignant germ cell tumor.
Symptoms depend on where the cancer returns and may include a new lump, swelling, pain, cough, abdominal discomfort, weight loss, or a rise in tumour markers even before symptoms appear.
Imaging helps show whether the cancer has returned, where it is, and whether it is limited to one area or has spread further.
CT, MRI, or ultrasound may be used in surveillance to look for recurrent masses or spread.
Management usually involves oncology-led reassessment with tumor markers, imaging, and further treatment planning.
This entry explains the condition. The next step is having a radiologist interpret your specific scan, not a general definition.
