4. COUGH OR HOARSENESS

Symptoms of lung, larynx, or thyroid cancers can be in the form of a cough or hoarse voice that never goes away. It could be a really bad case of a cough that prompts a visit to the doctor. Coughs are, to a huge degree, generally related to cancers in the upper or lower respiratory tracts. In other cases, coughs can be caused by metastasis in the lungs from cancers located in other areas.

Many of the patients who develop respiratory tract cancers were formerly smokers with the smoker’s cough already. That being the case, some patients think their cough is the usual case of smokers cough, ignorant of the fact that it’s already a symptom of cancer.
