Throat cancer generally is not contagious. Currently, the most accurate and fundamental etiology of throat cancer is not particularly clear. It may be related to genetic factors or issues with genes, or it could be due to long-term lifestyle habits, such as smoking, drinking alcohol, or exposure to irritating radioactive substances. Overall, from existing medical treatments and research, there is no evidence found of definite contagiousness. Thus, it is not considered an infectious disease, and excessive isolation is not necessary. Regarding treatment, it is primarily surgical-based at the moment, with some patients requiring a combination of radiotherapy or chemotherapy as comprehensive treatment methods. Also, long-term regular follow-ups are needed to monitor the recovery process.

The difference between throat cancer and pharyngitis.

Throat cancer and pharyngitis are two completely different diseases. Throat cancer is a common malignancy in the field of otolaryngology, whereas pharyngitis is caused by long-term chronic inflammation irritating the mucous membrane in the throat area, leading to symptoms such as the sensation of a foreign body in the throat, as well as dryness, itchiness, and pain in the throat. For patients with throat cancer and pharyngitis, diagnosis can be confirmed through the use of a laryngoscope, a nasopharyngoscope, and a CT scan of the neck with contrast enhancement. For patients with throat cancer, the primary treatment method is surgical removal of the tumor tissue. For patients with pharyngitis, the focus is on care. In daily life, it is advisable to avoid consuming spicy, irritating foods and cold drinks, while it is also important to eat more vegetables and fruits to protect the mucous membrane of the throat and to conserve the voice.

Is throat cancer prone to metastasize to the lungs?

Laryngeal cancer is a relatively common type of malignant tumor in the head and neck region. In its advanced stages, laryngeal cancer tends to metastasize, though the likelihood of metastasis to the lungs is relatively low. The most common type of metastasis occurs in the cervical lymph nodes, but some patients may also experience liver metastases, and bone metastases are also possible. The specific details of metastasis vary from person to person. It is crucial to seek medical attention from an otolaryngologist as soon as the disease manifests. If metastasis has occurred, the condition is generally more advanced and severe. In terms of treatment, most patients primarily receive a combination of radiotherapy and chemotherapy, while some may only undergo palliative treatment, which generally has poorer outcomes.

Early symptoms of throat cancer

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.

How long does it take for throat cancer to develop?

Throat cancer is a common malignant tumor in otolaryngology, which usually forms over the course of a year or half a year. However, patients typically have long-term chronic stimuli and medical history before the tumor changes occur, such as a long history of smoking or drinking, as well as exposure to physical and chemical factors. Early symptoms of throat cancer often include hoarseness, while in the mid to late stages, patients may experience difficulty swallowing and breathing difficulties. We can make a definite diagnosis through local pathological biopsy, electronic laryngoscopy, and CT scans of the throat area. Early detection of throat cancer should lead to timely surgical treatment, followed by radiotherapy and chemotherapy. For late-stage patients who are not suitable for surgery, chemotherapy or radiotherapy should be administered promptly to extend the patient's lifespan.

Which area is the most common site for laryngeal cancer?

Laryngeal cancer is a malignant tumor in the larynx, and clinically, it is primarily squamous cell carcinoma. The causes of laryngeal cancer are diverse, with major triggers being the irritation from smoking and alcohol, as well as viral infections. Clinically, laryngeal cancer is categorized into glottic cancer, supraglottic cancer, and subglottic cancer. The most common type is glottic cancer, which occurs on the vocal cords, typically affecting one vocal cord; bilateral occurrence is extremely rare. Glottic cancer, or cancer of the vocal cord area, is often detected early because hoarseness appears as soon as the lesion develops, prompting patients to seek early medical attention. Therefore, when detected early, the treatment outcomes are generally better.
