Is hoarseness definitely a symptom of lung cancer?

Lung cancer is a tumor that people are familiar with. Lung cancer also has many common symptoms, such as coughing and chest pain. However, there is another common symptom of lung cancer that is often overlooked, that is, hoarseness. Many people don't understand why lung cancer can also cause hoarseness? Here is an expert explanation: Lung cancer can indeed manifest as a symptom of hoarseness, and this symptom is relatively common. Now, let's take a look at this common symptom of lung cancer.

Hoarseness caused by lung cancer is due to the fact that the recurrent laryngeal nerve, which controls the left side of the vocal function, goes down from the neck to the chest, bypasses the large blood vessels of the heart and goes back up to the larynx, thus controlling the left side of the vocal organ. Therefore, if the tumor invades the left side of the mediastinum and compresses the recurrent laryngeal nerve, hoarseness will occur, but there will be no sore throat or other symptoms of upper respiratory tract infection. Among the common symptoms of lung cancer, most patients have hoarseness.

Hoarseness is a common symptom of lung cancer, and it is also a relatively serious symptom. Hoarseness can occur after pharyngitis, colds, acute bronchitis, thyroid surgery, and pharyngeal surgery. It can also occur after improper voice production, excessive speech, or even heavy smoking and drinking. However, this type of hoarseness can generally be treated symptomatically or healed by rest. The hoarseness caused by lung cancer, thyroid cancer, and laryngeal cancer is completely different from the above hoarseness, especially lung cancer. Therefore, we must not confuse the above hoarseness with the common symptoms of lung cancer.

In addition to hoarseness, there are many common symptoms of lung cancer, and we need to understand these symptoms because they play a good role in our treatment and prevention.
