My husband is hypothyroid and takes meds for same. I nor my family has ever had any thyroid diseases. I went to my doctor for listlessness, no energy and my blood results have come back hypothyroid and being given meds for same. We have known our house has radon over 4 but we never thought much about it and never gotten it taken care of. I developed somewhat of a cough and energy level isn't up to par and I've lost some weight. I am contemplating radon mediation and wondering if I should go back to doctor and have check for thyroid cancer?
