Thyroid calcification is not the same as nodules. Calcification occurs when calcium is deposited on the thyroid as blood moves through the body. On the other hand, a nodule is a lump, but is not caused by calcium being deposited on the thyroid.
Some have heard about an increased risk of thyroid cancer in those who have experienced thyroid calcification. This is not really true, and if you read on you will find an explanation about how that rumor may have been started.
To say that one is at an increased risk for a certain disease following the presence or occurrence of a primary condition insinuates that the primary condition was a contributing factor leading to the disease. In other words, that thyroid calcification leads to thyroid cancer. That is not the case.
In older women, the problem is often misdiagnosed. Because these calcifications often present as hard lumps, they are sometimes mistaken for cancer that originated in the breast or stomach. In addition to such misdiagnoses causing stress on the patient, it also puts off proper treatment of the actual problem.
Of course, if you feel any type of lump or hardening, it should not be ignored. It is possible that it is a calcification, but it could be something more serious. In any event, a lump of any sort is not normal and needs to be evaluated by a doctor.
As mentioned above, mistakes are sometimes made. That is why getting a second, unbiased opinion is always a good idea, especially when the diagnosis was serious and would require the patient to undergo unpleasant and potentially dangerous treatment.
Thyroid calcification is often harmless, but do not ignore it or there could be serious complications as a result.
