I'm really worried about some symptoms I've been having. I've had a productive cough and breathing issues for about a month. The doctor told me it was bronchitis and gave me medication like LezineM and Levoflox, which helped a lot, but now that I'm done with the treatment, the breathing issues are creeping back a bit. Also, I've noticed the lower part of my throat moves in and out when I breathe. My chest X-ray and blood work came back normal, and while I'm not coughing really hard, there's still a bit of it. Could these be signs of lung cancer?

no it cannot be a lung cancer
