Are all types of thyroid nodules / lumps cancerous?

Are all types of thyroid nodules / lumps cancerous?

No: The majority of lumps in the thyroid when noted to be multiple on scan represent the condition "multinodular goiter" These are almost always benign.

Do papillary and follicular thyroid cancers secrete thyroglobulin?

Do papillary and follicular thyroid cancers secrete thyroglobulin?

Yes: All cells of thyroid origin secrete thyroglobulin. Measuring it to follow a cancer ONLY makes since if the whole thyroid has been removed. If you have anti thyroglobulin antibodies, that makes thyroglobulin measurements unreliable. However, rising or decreasing anti thyroglobulin antibodies can be a proxy for thyroglobulin measurements. ...Read more

Do radiation therapy increase cancer cell growth of other undetected types of cancer?

Do radiation therapy increase cancer cell growth of other undetected types of cancer?

Even low doses for children to prevent brain relapse in leukemia has been linked to excess brain tumors. But second tumors do not occur in all. ...Read more
