C75.0: Malignant neoplasm: Parathyroid gland

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

The parathyroid glands are 4 small glands at the edge of the thyroid gland. A messenger substance is formed in the parathyroid glands. This messenger substance affects the calcium and phosphate content in the body. Calcium from the bone is dissolved by the messenger substance and released into the blood. It thus also affects bone firmness.

With cancer of the parathyroid gland, more messenger substances may be formed. This can alter bone metabolism. The bones can then get deformed or more easily break, for example. You can then have pain in your bones. You may also get kidney stones.

Not every cancer is the same. There are cancers that develop quickly. You may then quickly feel seriously ill. But there are also cancers that progress slowly. You may then feel generally unwell or weak, or even have no symptoms at all to start with.

Please note: This ICD code may also derive from the ICD-O system. If this is the case, there are usually additional letters and numbers in addition to the code. It starts with the letter M, followed by 4 digits and then a slash. There is another digit after the slash.

If it is an ICD-O code, then this does not describe a malignant cancer in all cases. The last digit after the slash gives you more detailed information about this:
