Stages of parathyroid cancer

Staging is a way of describing or classifying a cancer based on the extent of cancer in the body. There is no standard staging system for parathyroid cancer because:

  • It is rare.
  • Tumour size and lymph node status at the time of diagnosis are not prognostic factors for this type of cancer.

Parathyroid cancer is usually described as localized, metastatic or recurrent.

  • Localized parathyroid cancer means the cancer is found in a parathyroid gland. There may be spread to nearby tissues.
  • Metastatic parathyroid cancer means the cancer has spread beyond the tissues surrounding the parathyroid gland to other parts of the body.
  • Recurrent parathyroid cancer means that the cancer has come back after it has been treated. It may recur in the same location (local recurrence) as the original cancer or it may recur in another part of the body (metastatic parathyroid cancer).
