What are the early symptoms and signs of laryngeal cancer

The early symptoms and precursors of laryngeal cancer mainly include a foreign body sensation in the throat, hoarseness, coughing up blood, and swallowing difficulties.

1. Foreign body sensation in the throat: Laryngeal cancer is a malignant tumor in the throat. The increase in the size of the tumor may exert pressure on the surrounding area, causing the patient to have an obvious foreign body sensation in the throat.

2. Hoarseness: This is one of the typical early symptoms of laryngeal cancer. It is mainly due to the stimulation of the throat mucosa, which causes congestion and swelling, which in turn causes changes in the voice and even hoarseness.

3. Coughing and coughing up blood: Laryngeal cancer patients may also experience irritating coughs due to damage to the laryngeal mucosa. The laryngeal mucosa may also ulcerate, causing local rupture and bleeding, so patients may also experience coughing up blood.

4. Swallowing disorder: As the disease progresses, it may affect the patient's swallowing function, mainly manifested as obvious pain when swallowing food.

These symptoms are not unique to laryngeal cancer and may also be caused by other diseases. Patients are advised to go to a regular hospital and seek help from a professional doctor in a timely manner if they experience the above symptoms.
