This is how dangerous thyroid nodules are: there is a risk of atrial fibrillation and osteoporosis. Experts recommend having a laboratory test or an ultrasound scan from the age of 65.
To treat hot nodules, which are almost always benign, medication, especially radioiodine therapy or surgery, can sometimes be considered. In addition, so-called minimally invasive procedures are available for benign nodules. These often use special needles (“probes”): radiofrequency ablation or laser ablation.
