Hi I had an ultrasound that showed multinodular goitre, a cystic mass with solid components and thyroid lower poles reaching both sides of the neck, I have been feeling lethargic had weight loss and difficulty breathing I am concerned about thyroid cancer
You need further investigations. 1. Thyroid function tests TFS to see if you are hyperthyroid, thyroid or hypothyroid.2. An ultrasound of neck and an ultrasound guided FNAC (fine needle aspiration for cytology) of suspicious nodule in thyroid to get to a diagnosis. Dyspnea can be due to pressure on wind pipe from goiter. A chest radiograph should be done to see lungs for any abnormality. Weight loss can be due to a hyperfunctioning thyroid (Hyperthyroidism) but a malignancy should be suspected. I hope it helps. Please discuss it with your doctor.
