What is Neurofibrosarcomas?

18:51 - 5 October , 2023


Also called a malignant tumor of the peripheral nerve sheath, neurofibrosarcoma is a low-incidence cancer disease that appears in the lining of the nerves that go from the spinal cord to various areas of the body.

Although neurofibrosarcomas can appear in any area of the body, they are more frequent in:

  • Chest.
  • Arms.
  • Legs.

The cause of its appearance is unknown to date, but it is known that the development mechanism is when abnormal cells begin to multiply uncontrollably, accumulating and forming tumors.

Also, there are some potential risks to developing it such as:

  • Previous radiation therapy sessions.
  • Having suffered benign nerve tumors.
  • Having neurofibromatosis 1.

Diagnosis and treatment Neurofibrosarcomas

The doctor will analyze your symptoms and medical history before performing a physical examination in search of signs of cancer, as well as a neurological examination.

Subsequently, they will request various tests to rule out other conditions and confirm the diagnosis, such as:

  • X-rays.
  • MRI.
  • Computed tomography.
  • Positron emission tomography.
  • Tissue biopsy.

The treatment to be followed will depend on the size, location, and stage of the cancer, but generally includes:
Surgical removal of the tumor or in severe cases, amputation of the affected limb.

  • Radiation therapy.
