Yolk Sac Tumor
A yolk sac tumor is a malignant germ cell tumor that can arise in the ovaries, testes, or other sites and often affects younger patients.
When to get help quickly: Prompt specialist review is important for a new testicular lump, a growing abdominal or pelvic mass, unexplained swelling, or concerning scan findings in a child or young adult.
Common symptoms
Symptoms depend on where the tumour is. They may include a painless testicular lump, lower abdominal swelling or pain, a pelvic mass, changes in periods, or symptoms from a mass in the chest or abdomen.
When imaging helps
Imaging helps show where the tumour is, how large it is, and whether it has spread to nearby structures or other parts of the body.
What radiology does
Ultrasound, CT, and MRI can help show the mass and assess its extent, while imaging is also important for treatment follow-up.
What usually happens next
Management usually involves specialist cancer care, often including surgery and chemotherapy depending on the site and stage.
