Thyroid nodules are a common thyroid disease, and many thyroid diseases can manifest as nodules. Many patients with thyroid nodules will find calcification during the examination, but they do not know what is going on with calcification of nodules, and many patients will worry whether calcification means cancer. So, let’s learn about the relationship between calcification of thyroid nodules and cancer today. Calcification of thyroid nodules is a form of thyroid tumor, which is related to thyroid cancer. Generally, about 25% of thyroid nodules show calcified shadows, while 50% to 62.5% of thyroid cancers have calcification. The relationship between calcification of thyroid nodules and cancer: 1. Calcification of sandy thyroid nodules, calcification of thyroid nodules is almost common to malignant thyroid tumors, and calcification of thyroid nodules is often a characteristic manifestation of papillary carcinoma. Among the calcified thyroid nodules, about 10% to 20% are carcinoma, among which follicular adenocarcinoma accounts for a large proportion. Medullary carcinoma is often mixed with coarse particles and sand-like calcifications. 4. Generally, calcification images of benign thyroid tumors are dense with clear margins, while malignant tumors are faint and blurred. Calcification of thyroid nodules is almost a common feature of malignant thyroid tumors, but calcification is not equal to cancer. Calcification is the stone. After seeing calcification, it is more important for us to see if the surrounding soft tissues have the characteristics of malignant tumor, and if there are no characteristics of malignant tumor, we should not draw a conclusion of cancer.
