A 28-year-old member asked:

Besides genetics, what determines the chance of a solid thyroid nodule being cancerous? I have a solid nodule that has grown fast and normal TSH level

Cancer risk: Risk of cancer is higher in patients < 20 and > 70, and in males. Concern for cancer higher if fixed (non-mobile), fast growing, lymph nodes in the neck, firm/hard, history of neck radiation, problems swallowing/talking/breathing. A TSH that is normal is actually more concerning as well. Typically if > 1cm and normal tsh, biopsy is performed. Especially if any other risk factors present.

Adenoma: If there is a solitary thyroid gland nodule, that has been removed and examined under a microscrope using sections taken from the tumor, is called an adenoma. If there is invasion, then it is a carcinoma. There are some rare benign tumors (teratoma, solitary fibrous tumor, trabecular hyalinizing tumor) that could be a benign thyroid tumor.

No: Though thyroid hormone replacement may improve your symptoms, you TSH isn't high enough to justify blaming your symptoms on an underactive thyroid gland. You should talk to your doctor to determine if you are experiencing side effects of other medication, have nutritional deficiencies or maybe suffer from sleep apnea. And depending on your age, several other abnormalities can lead to your symptoms.

Yes: It would be a good idea to get it checked as levels and dosage requirements often change with pregnancy.
