Key points about teratoma

  • A teratoma is a tumor made of tissues like hair, bone or muscle
  • It begins in special cells that can turn into many tissue types
  • It can be benign (non-cancerous) or malignant (cancerous)
  • Common in areas like the ovaries, testicles or tailbone
  • Found in both children and adults

Teratoma causes

Teratomas form when germ cells grow abnormally. These cells are meant to become parts of the body during early development.

  • Early cell development that goes off track
  • Rapid or uncontrolled growth of germ cells
  • Genetic conditions that affect cell behavior

Teratoma risk factors

Risk depends on age, genetics and where the tumor forms.

  • Genetic disorders like Klinefelter syndrome
  • Family history of germ cell tumors
  • More common in newborns, teens and young adults
  • Being born with ovaries or testicles

Teratoma symptoms

Symptoms vary based on the tumor's size and location.

  • Swelling or a painless lump
  • Pain in the abdomen, pelvis or chest
  • Trouble with urination or bowel movements
  • Never or fatigue if the tumor gets infected
  • No signs at all in some cases

Teratoma diagnosis

Doctors use different tools to confirm the diagnosis and plan treatment.

  • Ultrasound to spot the mass
  • MRI or CT scan to see inside the body
  • Blood tests to look for tumor markers
  • Biopsy to confirm if it's benign or cancerous

Teratoma treatment

Treatment depends on whether the tumor is benign or malignant.

  • Surgery to remove the teratoma
  • Chemotherapy if the tumor is cancerous or spreading
  • Monitoring small, harmless tumors over time

When to seek care

Talk to your doctor if you experience:

  • A lump or swelling anywhere on your body
  • Unusual or ongoing pain
  • Problems going to the bathroom
  • Fever, weakness or signs of infection
