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.

Stage II throat cancer is the situation.

The so-called Stage II laryngeal cancer refers to the degree of differentiation of cancer cells, classified as moderately malignant. This type of differentiated cancer cells has a tumor growth rate that is between Stage I and Stage III, and shows certain characteristics of invasion and metastasis. Stage II laryngeal cancer generally tends to metastasize via the lymphatic pathways, and some patients may also experience hematogenous pathway metastasis. Clinically, patients with Stage II laryngeal cancer may present with symptoms localized to the larynx as well as symptoms of metastatic sites. Patients may experience symptoms such as hoarseness, cough, expectoration, and a foreign body sensation in the throat. When metastasis occurs, respiratory symptoms like coughing and coughing up blood can appear.

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.

How to diagnose throat cancer

Laryngeal cancer examinations are mainly divided into two categories. The first category is laryngoscopy, and the second is imaging studies. Laryngoscopy is further subdivided into fiberoptic laryngoscopy, electronic laryngoscopy, and indirect laryngoscopy. Indirect laryngoscopy is relatively rudimentary and generally doesn't play a significant role in diagnosing laryngeal cancer. Therefore, fiberoptic or electronic laryngoscopy is typically preferred as these methods can directly determine the presence of neoplasms in the throat. If a neoplasm is detected, further pathological biopsy testing can be considered. The other method is imaging studies, primarily involving CT scans or MRI of the throat. These are helpful in determining the size, extent, and preliminary nature of the throat neoplasms. Combined with the above methods, a definitive diagnosis can generally be established.

Can throat cancer be detected by a CT scan?

Most laryngeal cancers can be detected through CT scans because, during the scan, it is possible to see whether there are neoplasms in the area of the pharynx and larynx, especially around the laryngeal cavity, ventricle, and vocal cords. Generally, if there are any growths, they will be visible on a CT scan. However, some early-stage laryngeal cancers, where the mucosa has just started to show changes, might be missed by CT scans. In such cases, it is generally recommended to also perform a laryngoscopic examination. If possible, conducting an NBI (Narrow Band Imaging) laryngoscopy could reveal early mucosal changes. If early-stage laryngeal cancer is confirmed by pathology, surgical or radiation treatment can be very effective and generally has a low chance of recurrence.

What causes throat cancer?

Throat cancer is a malignant tumor that occurs in the throat area. Its causes are not clear, but it is generally associated with long-term smoking, drinking, exposure to toxic and carcinogenic substances, as well as gastrointestinal dysfunction, acid reflux irritation, prolonged loud speaking, staying up late, fatigue, and malignant transformation of benign tumors, which lead to symptoms in the throat area. It causes persistent hoarseness in patients, and the symptoms progressively worsen. Patients may also experience a foreign body sensation in the throat, a feeling of blockage, a burning sensation, and sometimes difficulty swallowing. Patients should first go to the hospital for a detailed examination with an electronic laryngoscope, which can reveal cauliflower-like neoplasms or ulcers in any part of the throat. If such findings are present, a local biopsy is needed. If the biopsy confirms the presence of a malignant tumor, local surgery, radiotherapy, or chemotherapy is required for treatment.
