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.

Dietary considerations for laryngeal cancer

Patients with throat cancer need to pay attention to the following aspects in their diet: First, it is recommended to adhere to a light diet, avoiding particularly greasy foods and opting for high-protein, low-fat foods. Second, it is recommended to eat soft or semi-liquid foods, and avoid particularly hard foods, as hard foods may cause swallowing obstructions and potentially damage the mucous membranes of the throat. Third, it is advised not to eat cured products and to reduce the intake of salty foods, as these foods may exacerbate the condition of throat cancer and potentially lead to cancer in other parts of the body.

Pre-cancerous symptoms of throat cancer

Laryngeal cancer is a common disease in otolaryngology and a type of malignant tumor, which is divided into primary laryngeal cancer and secondary laryngeal cancer. The main clinical symptoms of laryngeal cancer in its early stages often include hoarseness, cough, and lymph node enlargement, among others. Patients can use indirect laryngoscopy or electronic nasopharyngoscopy to detect tumors located in the pharyngeal area, and a local pathological biopsy can be performed for diagnosis. When the tumor is identified as malignant, it is essential to initiate prompt and active treatment. The common method is to surgically remove the detected tumor to achieve clinical cure.

Is stage 2 laryngeal cancer considered early stage?

Throat cancer is a relatively common otolaryngological disease, and clinically it is divided into four stages: stage I, stage II, stage III, and stage IV. Stage II is considered mid-stage, while stages III and IV are considered late-stage or very late-stage. In terms of treatment, most patients can opt for surgical removal. After the surgery, the pathological biopsy results, combined with the presence of lymph node metastasis in the neck and preoperative CT scans, are considered comprehensively. Some patients may solely undergo surgery as their treatment, while others may require additional radiotherapy after surgery. The main aim is to reduce the chances of postoperative recurrence, and it is necessary to undergo regular long-term check-ups, generally recommended every three months, to confirm whether there is any recurrence after the surgery.

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.

Can throat cancer be cured?

Throat cancer is a relatively common type of head and neck malignancy with a high clinical incidence. Most patients require surgical treatment, and some need comprehensive treatment combining radiotherapy and chemotherapy. Generally, patients diagnosed in the early stages have better treatment outcomes and higher five-year survival rates. Typically, achieving a five-year survival rate after standardized surgery or radiotherapy and chemotherapy is considered a clinical cure. However, the proportion of patients in the middle to late stages achieving this is relatively low. Therefore, regular follow-ups are necessary to monitor the recovery process, regardless of the stage or type of the disease.
