Learn About Parathyroid Cancer
Parathyroid cancer is a cancerous (malignant) growth in a parathyroid gland.
Parathyroid carcinoma
The parathyroid glands control the calcium level in the body. There are 4 parathyroid glands, 2 on top of each lobe of the thyroid gland, which is located at the base of the neck.
Parathyroid cancer is a very rare type of cancer. It affects men and women equally. The cancer often occurs in people older than 30.
The cause of parathyroid cancer is unknown. People with a genetic conditions called multiple endocrine neoplasia type I and hyperparathyroidism-jaw tumor syndrome have an increased risk for this disease. People who had head or neck radiation also may be at increased risk. But this type of radiation is more likely to cause thyroid cancer.
Symptoms of parathyroid cancer are mainly caused by a high level of calcium in the blood (hypercalcemia), and may affect different parts of the body.
Symptoms include:
- Bone pain
- Constipation
- Fatigue
- Fractures
- Frequent thirst
- Frequent urination
- Kidney stones
- Muscle weakness
- Nausea and vomiting
- Poor appetite
The following treatments may be used to correct hypercalcemia due to parathyroid cancer:
- Fluids through a vein (IV fluids)
- A natural hormone called calcitonin that helps control the blood calcium level
- Medicines that stop the breakdown and reabsorption of bones in the body
Surgery is the recommended treatment for parathyroid cancer. Sometimes, it is hard to find out if a parathyroid tumor is cancerous. Your provider may recommend surgery even without a confirmed diagnosis. Minimally invasive surgery, using smaller cuts, is becoming more common for parathyroid disease.
If tests before the surgery can find the affected gland, surgery may be done on just one side of your neck. If it isn't possible to find the problem gland before surgery, the surgeon will look at both sides of your neck.
Chemotherapy and radiation don't work well to prevent the cancer from coming back. Radiation may help reduce the spread of cancer to the bones.
Repeated surgeries for cancer that has returned may help:
- Improve the survival rate
- Reduce the severe effects of hypercalcemia

Parathyroid cancer is slow growing. Surgery may help extend life even when the cancer spreads.
The cancer may spread (metastasize) to other places in the body, most often the lungs and bones.
Hypercalcemia is the most serious complication. Most deaths from parathyroid cancer occur due to severe, difficult-to-control hypercalcemia, and not the cancer itself.
The cancer often comes back (recurs). Further surgeries may be needed. Complications from surgery can include:
- Hoarseness or voice changes as a result of damage to the nerve that controls the vocal cords
- Infection at the site of surgery
- Low level of calcium in the blood (hypocalcemia), a potentially life-threatening condition (presenting as twitching movements or even seizures)
- Scarring
Contact your provider if you feel a lump in your neck or experience symptoms of hypercalcemia.
Background: People have 4 parathyroid glands near the thyroid gland in the neck. Surgery is needed to remove a parathyroid gland that is too large or has a tumor. These glands can be in different places, so doctors use an imaging scan with contrast dye to help find them before surgery. Researchers want to know if a different type of scan and a new tracer can make it easier to find the tumors in the parathyroi...
Summary: The ANTARES study is a phase II basket trial designed to evaluate the tissue-agnostic efficacy of the monoclonal anti-PD1 antibody, nivolumab, in patients with advanced or metastatic rare tumors. The study aims to treat rare malignancies with PD-L1 expression (CPS ≥ 10), regardless of the tumor's tissue type or location. Patients who have not responded to standard treatments will be included, and ...
