14. Hoarseness
This happens in patients with lung cancer in the midline or very close to the midline. They have changes in their voice tone and can complain of hoarseness. This is because the laryngeal nerve is compressed. This nerve comes from the vagus nerve and runs very low to go back up and reach the larynx. The left recurrent laryngeal nerve is more susceptible to compression because it is further down in the thorax.
