Told me not to worry about the lump in my neck. Told me that I had a better chance of getting hit by a truck rather than dying from the lump. When I told him about my symptoms he made light of them...I compared my symptoms to the posters on the wall regarding hypothyroidism....he told me not to pay attention to them...that the companies just give them to doctors for office decoration. Went to another doctor who truly cared and listened to me- diagnosed with thyroid cancer- don't go to him
