What are the symptoms of subglottic laryngeal cancer

Nowadays, more and more people are suffering from laryngeal cancer. This is a more serious cancer. The most obvious change of laryngeal cancer can be diagnosed from the voice. Breathing will also be disturbed. Let's learn more about the symptoms of different types of laryngeal cancer. I hope it can help everyone.

1. Supraglottic laryngeal cancer

Most of them originate from the root of the lingual surface of the epiglottis. There are no symptoms in the early stage. Even when the tumor develops to a considerable extent, there are only mild or non-specific sensations, such as itchy throat, foreign body sensation, swallowing discomfort, etc. Breathing will also be disturbed. It often causes alarm only when the tumor metastasizes to the lymph nodes. This type of tumor is poorly differentiated and develops quickly. When deep infiltration occurs, there may be throat pain, which radiates to the ears.

If the tumor invades the spoon-shaped cartilage, the glottis, or the recurrent laryngeal nerve, it can cause hoarseness. In the late stage, patients will experience breathing and swallowing difficulties, cough, blood in sputum, hemoptysis, etc. Therefore, middle-aged and older patients who have persistent throat discomfort should pay attention to it, check it in time, detect the tumor early, and treat it.

2. Glottic laryngeal cancer

Since the primary site is the vocal cord, the early symptoms are changes in voice, such as tiredness and weakness in pronunciation, which can be easily mistaken for "pharyngitis". Therefore, people over 40 years old with hoarseness for more than 2 weeks should undergo a careful laryngoscopy. As the tumor progresses, hoarseness may worsen or even cause loss of voice. Increased tumor size may cause difficulty breathing.

In the late stage, as the tumor spreads to the supraglottic area or subglottic area, it may be accompanied by radiating ear pain, dyspnea, dysphagia, dysphagia, and bad breath. Finally, death may occur due to massive bleeding, aspiration pneumonia, or cachexia. This type of disease is generally not easy to metastasize, but lymph node metastasis will soon occur if the tumor breaks through the glottis area.

3. Subglottic laryngeal cancer

This type is rare, and the primary site is below the vocal cord plane and above the lower edge of the cricoid cartilage. Due to its hidden location, early symptoms are not obvious and it is easy to misdiagnose. When the tumor develops to a considerable extent, irritating cough and hemoptysis may occur. Subglottic blockage may cause breathing difficulties

When the tumor invades the vocal cords, hoarseness occurs. For patients with unexplained aspiration dyspnea and hemoptysis, carefully examine the subglottic area and trachea.

4. Transglottic laryngeal cancer

It refers to laryngeal cancer that originates in the laryngeal cavity and spans the supraglottic and glottic regions. It is difficult to detect in the early stages, and the tumor develops slowly. It takes more than six months from the first symptom to a clear diagnosis.
