The early symptoms of laryngeal cancer vary depending on the type, as laryngeal cancer is categorized into three types. The most common type, accounting for over 80%, is glottic cancer. The early symptom for this type is primarily hoarseness, making it the type of laryngeal cancer where symptoms appear earliest. The other two types are supraglottic and subglottic cancer. These types are less likely to show early symptoms, or the symptoms may not be typical and easily noticeable or taken seriously. The main symptom is a foreign body sensation in the throat, which is often mistaken for pharyngitis or laryngitis and not given due attention. Therefore, when experiencing persistent hoarseness or a noticeable foreign body sensation in the throat, and if throat discomfort persists, it is advised to visit the Ear, Nose, and Throat (ENT) department of a hospital promptly for an examination with an electronic laryngoscope. This can help in the early detection, exclusion, and diagnosis of the condition.

What are the symptoms of early-stage throat cancer?

The early symptoms of laryngeal cancer vary: some people exhibit typical symptoms while others show atypical symptoms or even no symptoms initially. For glottic laryngeal cancer, one of the earlier symptoms is hoarseness. This type of cancer occurs in the vocal cords area, which can affect closure of the vocal cords during speech, causing hoarseness. Some patients may also experience throat pain, abnormal bloody discharge from the throat, or have difficulties in breathing and swallowing, which could all be symptoms of laryngeal cancer. However, some patients may not show any symptoms in the early stages, especially those with supraglottic or subglottic laryngeal cancer, where early symptoms are not typical. Symptoms might only appear in the mid to late stages. Therefore, it is necessary to use a laryngoscope for examination and to perform a neck CT for a comprehensive evaluation.

Can throat cancer patients eat sea cucumber?

Patients with throat cancer can eat sea cucumbers, which contain rich proteins, trace elements, amino acids, and other components that are very beneficial to health. These can help improve the patient's immune function and resist the occurrence of tumors. Additionally, patients should eat more vegetables and fruits containing vitamins to help enhance their immune function. For diagnosing throat cancer, we mainly use electronic nasopharyngoscopy and CT scans of the throat area to make a clear diagnosis. After throat cancer occurs, we usually perform surgery as soon as possible to remove the tumor while trying to preserve as much of the patient's laryngeal function as possible, in order to improve the patient's quality of life.

The difference between laryngeal cancer and pharyngeal cancer

The main difference between laryngeal cancer and pharyngeal cancer lies in the different parts they affect. Laryngeal cancer occurs below the level of the epiglottis, while pharyngeal cancer generally occurs above this level, including tumors in the pharynx, tonsils, and base of the tongue, whereas laryngeal cancer primarily involves the vocal cords and the lower pharynx. For the diagnosis and treatment of pharyngeal and laryngeal cancers, we can use nasoendoscopy, paranasal sinus CT scan, and CT scan of the larynx among other examinations to make a clear diagnosis, and a pathological biopsy for final confirmation. Once diagnosed, it is usually necessary to surgically remove the tumor promptly to achieve a cure.

Can throat cancer be contagious?

Laryngeal cancer is a malignant tumor of the larynx, which is clinically primarily squamous cell carcinoma and belongs to epithelial malignancies. Generally, epithelial malignancies are not contagious. However, laryngeal cancer may sometimes be related to certain viral infections, such as papillomatosis, which might be contagious. This is an aspect of its etiology, but laryngeal cancer itself is not contagious. In summary, laryngeal cancer is not contagious. It is a malignant tumor disease, and its clinical treatment mainly involves surgical intervention, which can be supplemented with radiation therapy and other treatments.

Precursors of throat cancer

Nasopharyngeal cancer, located behind the nasal cavity and above the oropharynx, is generally difficult to diagnose early due to its concealed location. However, there are early signs, such as nasopharyngeal bloodstained mucus experienced during sniffing, which should raise suspicions of nasopharyngeal cancer. Additionally, early-stage nasopharyngeal cancer may present with unilateral nasal obstruction, which gradually progresses to more severe blockage. Another indication is the presence of a neck lump or enlarged lymph nodes, which also suggests the possibility of nasopharyngeal cancer. Other nonspecific reactions, such as dermatitis, dermatomyositis, or a general skin rash, should also be considered potential indicators of nasopharyngeal cancer. These signs require attention.
