What are the early symptoms of laryngeal cancer?

The larynx is an important organ of the human body, with functions of breathing, pronunciation and protection. However, in recent years, laryngeal cancer has become one of the most common malignant tumors in the otolaryngology department. Let's learn about the early symptoms of laryngeal cancer.

Laryngeal cancer is a malignant tumor originating from the epithelial tissue of the laryngeal mucosa. The most common laryngeal cancer is laryngeal squamous cell carcinoma. It is more common in middle-aged and elderly men. The occurrence of this cancer is related to factors such as smoking, alcoholism, long-term inhalation of harmful substances and papillomavirus infection. The incidence of laryngeal cancer accounts for about 1-5% of all tumors in the body. In the field of otolaryngology, it ranks third after nasopharyngeal cancer and nasal and sinus cancer. The most common age is 50-70 years old. It is more common in men than in women.

According to the location of the tumor, it is divided into three different types: (i) supraglottic type, (ii) glottic type, and (iii) subglottic type.

The stages of laryngeal cancer are: stage I, stage II, stage III, and stage IV.

Experts warn that if laryngeal cancer is detected and treated early, it can not only be completely cured, but also the laryngeal function can be preserved to the maximum extent, improving the patient's quality of life.

Experts point out that in addition to smoking, laryngeal cancer is also related to excessive drinking, chronic inflammatory stimulation such as chronic laryngitis or respiratory inflammation, air pollution, viral infection, sex hormones, precancerous lesions, etc. If you find yourself experiencing the following symptoms, you must be vigilant and go to the hospital for examination as soon as possible, because these symptoms are likely to be early symptoms of laryngeal cancer.

The diagnosis of this disease is based on unexplained progressive hoarseness, foreign body sensation in the throat, cough, blood in sputum, dysphagia with pain, and difficulty breathing. This disease should be highly suspected and a laryngoscopy can be performed. . Indirect laryngoscope is generally used to observe changes in the larynx and the activities of the vocal cords, epiglottis, etc., and whether there are local neoplasms, ulcers, etc., and smears or biopsies can be performed when necessary. In recent years, the advent of fiber laryngoscopes and microlaryngoscopy has provided convenience for the early diagnosis of laryngeal cancer. If multiple biopsies are negative, but laryngeal cancer cannot be ruled out, a laryngeal fissure biopsy can be performed for diagnosis. In addition, X-ray frontal and lateral films can observe the location, size, range, shape and cartilage involvement of the lesion. In short, based on the medical history and laryngoscope examination of living tissue, it is generally not difficult to diagnose.

Symptoms of laryngeal cancer: hoarseness: in the early stage, the patient may feel tired or hoarse when speaking, but there is no other discomfort. It is often mistaken for a cold or laryngitis. Anyone over 40 years old, especially men and long-term smokers, who has hoarseness for more than 3 weeks and has not improved after voice rest and general treatment, must go to the hospital for a laryngoscopy.

Symptoms of laryngeal cancer: Pharyngeal discomfort and foreign body sensation: These are early symptoms of supraglottic laryngeal cancer, but they should be distinguished from the symptoms of chronic pharyngitis.

Symptoms of laryngeal cancer: Sore throat: The tumor invades deep into the body, causing intermittent pain at first, followed by continuous pain, and causing simultaneous reflex ear pain. The sore throat leads to difficulty in swallowing.

Symptoms of laryngeal cancer include coughing and coughing up blood: In the early stages, there is mostly coughing, without sputum or only a small amount of sputum, and no coughing up blood. As the disease progresses, blood in the sputum may appear, and even coughing up blood may appear.

Laryngeal cancer symptoms: dyspnea: dyspnea is often a symptom of late-stage laryngeal cancer.

Swollen lymph nodes in the neck: Especially for patients with supraglottic laryngeal cancer, swollen lymph nodes in the neck are likely to occur in the early stage.
