Hello, I quit smoking almost two months ago. I have been a smoker for close to 12 years. I am a 32 y/o female 5 9 170 pounds. I recently found a lump on my throat and had it examined by our family physician. He said it s a thyroid nodule and suggested I make an appointment to have bloodwork and an ultrasound performed. The mass is relatively firm and moves a bit. It is almost directly on the isthmus. I would guess that it is about the size of a marble. I am concerned that it may be cancer, but obviously cannot know for sure until I have the ulstrasound. I was wondering if there is any connection between quitting smoking and the sudden appearance of this nodule?
