Short answer
If thyroid nodules are detected, it is necessary to do an ultrasound and check the TSH level. Further tactics depend on the size of the node and hormonal status - observation or consultation with an endocrinologist.
Focal formations in the thyroid tissue requiring monitoring and differential diagnosis
The mechanism in three steps, and where you can intervene.
Trigger
Iodine deficiency, radiation, hereditary predisposition
Mechanism
Compensatory proliferation of thyrocytes with the formation of local foci
Symptom
Detection by palpation or ultrasound, swallowing disturbances are possible with large sizes

How each marker relates to thyroid nodules.
Thyroid nodules most often occur due to chronic iodine deficiency, especially in regions with low levels of this microelement in soil and water. Other precipitating factors include exposure to ionizing radiation, hereditary syndromes (eg, Cowden syndrome), and autoimmune processes. With age, the likelihood of nodule formation increases - after 50 years, they are detected in 50% of the population.
The key test is TSH to assess thyroid function. If an autonomously functioning node is suspected, FT3 and FT4 are additionally examined. Ultrasound allows you to determine the size, echogenicity, presence of microcalcifications and blood flow in the node. Measurements greater than 1 cm or suspicious ultrasound findings may require fine needle aspiration biopsy (FNA).
Consultation with an endocrinologist is necessary if the node grows rapidly (an increase of 2-3 mm over 6 months), hoarseness occurs, or difficulty swallowing or breathing. Alarming signs on ultrasound are hypoechogenicity, uneven contours, microcalcifications. In patients with nodes larger than 1 cm and TSH levels below normal, scintigraphy is indicated to exclude toxic adenoma.
Mistake #1 - panic when detecting a node: 90-95% of nodes are benign. Mistake No. 2 - ignoring control: even small nodes require ultrasound monitoring once every 6-12 months. Error No. 3 - uncontrolled intake of iodine without preliminary testing of TSH and antibodies. Mistake #4 - refusing a biopsy if indicated due to fear of the procedure.

Small colloidal nodes (up to 1 cm) sometimes shrink or stabilize without treatment. However, most nodes persist for life, requiring only observation.
For nodes up to 1 cm without suspicious signs - once every 12-24 months. For nodes larger than 1 cm or with abnormalities on ultrasound - every 6 months. Axioris will help you not to miss deadlines for control studies.
Yes, if the nodes are small and do not cause discomfort. An exception is sports with a risk of hits to the neck (martial arts, rugby). In case of toxic adenoma, physical activity is discussed with an endocrinologist.
Only if the node autonomously produces hormones (toxic adenoma), causing symptoms of hyperthyroidism. Most nodes do not affect metabolism or weight.
Absolute indications for surgery: malignant process on biopsy, compression of neck organs, toxic adenoma. Small benign nodes are removed only for cosmetic reasons.
