Thyroid found to be slightly heterogeneous on ultrasound. Isoechoic nodule measuring 7mm mid left lobe. Fam history of thyroid cancer. Concerning?

Not concerning. Isoechoic thyroid nodules are generally not concerning especially when they are less than 1.5 cm and if they don't have suspicious features like microcalcifications and increased internal vascularity. I recommend repeat thyroid US in 1 year. Make sure you have got your TSH and Free T4 checked.
