At present, laryngeal cancer is classified based on anatomical location into three main types, with glottic cancer being the most common. Supraglottic and subglottic cancers are relatively less common. The primary symptom of glottic cancer is hoarseness, which can be noticeable in the early stages. Therefore, generally, the earlier the disease is diagnosed, the better the treatment outcome may be. Additionally, laryngeal cancer is also classified by pathological types. The main pathological type is squamous cell carcinoma. Overall, surgical treatment is the most important, but depending on the patient's stage and type of cancer, a combination of radiation and chemotherapy might be necessary.

How is laryngeal cancer diagnosed?

In clinical settings, the diagnosis of laryngeal cancer primarily relies on several aspects. Firstly, the patient's history, such as a family history of laryngeal cancer, and whether there is a long-term smoking history, for example, smoking two packs a day. Secondly, we need some clinical data, such as whether the patient exhibits symptoms like hoarseness. Then, during physical examination, we need to check for the presence of cancerous tissues in the hypopharynx, vocal cords, and the subglottic cavity, such as the presence of lumps, uneven surfaces, erosion, ulcers, etc. These are its symptoms and signs. Furthermore, we can utilize some auxiliary examinations, such as laryngoscopy, which allows direct observation of the tumor tissue. However, the definitive test involves taking a sample of the tumor tissue for a biopsy, identifying the presence of tumor cells, i.e., cancer cells. This result serves as the basis for confirming a diagnosis of laryngeal cancer. Of course, other auxiliary examinations like CT scans and MRI can also assist in diagnosing laryngeal cancer.

Is a hoarse voice an indication of throat cancer?

Hoarseness does not necessarily indicate laryngeal cancer because there are many diseases that can cause hoarseness. Common ones include vocal cord nodules, vocal cord polyps, acute laryngitis, chronic laryngitis, vocal cord grooves, and laryngeal cancer. The primary approach should be to visit an ENT (Ear, Nose, and Throat) department in a hospital, undergo an electronic fibrolaryngoscopy, and then determine the specific lesion based on the examination results. It is incorrect to diagnose laryngeal cancer based solely on hoarseness. For instance, some types of laryngeal cancer, such as supraglottic or subglottic, may cause hoarseness symptoms to appear late or even not at all. Therefore, while hoarseness does not necessarily mean laryngeal cancer, laryngeal cancer can potentially cause hoarseness. It is crucial to seek timely medical attention and undergo electronic fibrolaryngoscopy for a basic definitive diagnosis when hoarseness occurs. Apart from diseases of the throat, conditions affecting the thyroid, mediastinum, and esophagus can also cause hoarseness when they progress to a certain stage. Thus, hoarseness is a symptom that can be caused by many diseases, but it is not necessarily indicative of laryngeal cancer. Supraglottic laryngeal cancer, however, can manifest hoarseness as an early symptom. Therefore, it is critical to seek medical attention promptly once this symptom occurs.

Common sites of laryngeal cancer

Laryngeal cancer is a malignant tumor in the larynx, and clinically, it is primarily squamous cell carcinoma. There are several types of laryngeal cancer: firstly, glottic cancer; secondly, supraglottic cancer; there is also subglottic cancer, and transglottic cancer that spans two regions. Among these types, glottic cancer is the most common. Early-stage glottic cancer is generally detected earlier due to hoarseness, and the outcomes after surgery are relatively better. Consequently, the most frequently diagnosed site of this disease is the vocal cords. After surgery, regular follow-up appointments are necessary to monitor and observe the healing process post-operation.

Symptoms of throat cancer

Laryngeal cancer is a relatively common otolaryngological disease, with numerous clinical symptoms. Common symptoms include recurrent sore throat, foreign body sensation in the throat, and hoarseness. Some patients may not exhibit obvious clinical signs in the early stages and are often diagnosed during laryngoscopy or physical examinations. In terms of treatment, it is first necessary to perform laryngoscopy and a neck CT scan to assess the extent of the disease. Most patients primarily undergo surgical treatment, while some may need to consider a comprehensive treatment plan that includes radiation therapy or chemotherapy. After treatment, regular follow-ups are required to monitor the effectiveness.

Is T2N0M0 throat cancer serious?

Laryngeal cancer T2N0M0 refers to Stage 2 clinical staging of laryngeal cancer. Here, "T" denotes the primary lesion, typically classified as Stage 2. Stage 1 generally refers to the primary tumor, with Stage 2 lesions being larger in scope than Stage 1. "N0" indicates the local lymph nodes, showing that there is no local lymph node metastasis. "M0" indicates there is no distant metastasis. Therefore, laryngeal cancer T2N0M0 represents an early or intermediate stage. Clinically, this stage is usually most suitable for surgery, and the healing and prognosis after surgery are relatively favorable.
