My thyroid gland has a heterogeneous appearance. The right thyroid lobe measures 4.6x1.4x1.5 cm. the left thyroid lobe measures 4.7x1.4x1.5 cm. the thyroid isthmus measures approximately 0.4 cm in thickness. There is evidence of a 5.0 mm hypoechoic nodule in the mid pole of the right thyroid lobe as well as a small, 4.0 mm, cyst in the right thyroid lobe. My mother had thyroid cancer. What do you recommend for me to do?
