Ct scan shows small calcific densities measuring 3.5mm in the right lobe of thyroid gland. any suggestions on what this could be please? i had breast cancer in 08 but no mestateses and n full remission w br ca. tysvm! i love you guys.

Many things: Thyroid calcifications are relatively common. Some of them are an indication of thyroid cancer. The first thing to do is to get a neck ultrasound, which is better than ct in visualizing the thyroid, and thyroid function tests.

Curiosity has: Killed the cat, and satisfaction costs false positives and findings we do not need to know about. Unlike mamograms where calcium poit the way to cancer in breast, these tiny calcifications are meaningles in thyroid. May indicate "burnt out" thyroiditis. Check t-3, tsh, maybe u/s, but not related to breast ca. Probably nothing. You do not need screening ct 4 years out from br ca.

Calfifications: These likely represent small thyroid nodules. Calcification is more concerning for the possibility of cancer. The nodules are very small. They may require biopsy, however, especially given the history. See a board-certified endocrinologist.

3.5 mm calcification: These are likely benign. Microcalcifications, less than 1 mm, can be psamoma bodies associated with papillary thyroid cancer. With your history, and known association between breast and thyroid cancers, I would at least get an ultrasound guided biopsy of it.
