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.

What foods should be eaten for throat cancer?

Laryngeal cancer is a common malignant tumor in everyday life. In the early stages, patients with laryngeal cancer usually experience symptoms such as hoarseness, coughing, and a foreign body sensation. In the middle and late stages, patients may suffer from breathing difficulties or even choking, as well as swallowing difficulties. When symptoms of laryngeal cancer appear, we should initially complete examinations with an electronic laryngoscopy, laryngeal CT scan, and pathological biopsy to determine the pathological type of the patient, to confirm the diagnosis. At the same time, we should pay attention to a light diet, primarily warm, cold, and semi-liquid foods, and avoid smoking and drinking alcohol. Additionally, we should detect tumors early and treat them promptly through surgery.

T2N0M0 in throat cancer indicates stage 2 cancer.

Patients with mid-stage laryngeal cancer generally have a less severe condition and the scope of the lesion is relatively limited. In terms of treatment, most patients can opt for surgical removal. It is recommended to undergo a radical resection. After the surgery, based on the pathology lab results and the doctor's clinical experience, some patients might also need to consider undergoing radiation therapy. This serves as an adjunct treatment that can reduce the likelihood of recurrence. However, some patients might achieve good therapeutic results with just the surgery alone. After treatment, regular follow-up visits are necessary to monitor the effectiveness of the treatment and to check for any local recurrence or distant metastasis.

What should I do if I have a cough from throat cancer?

Laryngeal cancer is a common malignant tumor in otolaryngology. Patients with laryngeal cancer often experience coughs primarily because of the presence of tumors at the glottis, which then cause irritative coughs. For patients with the aforementioned symptoms, we should first diagnose the disease using a laryngoscope and CT scans of the throat area. Subsequently, it is crucial to remove the tumor through surgery as early as possible to achieve a complete cure. Post-surgery, patients usually undergo radiotherapy and chemotherapy. In the early stages before surgery, when the patient suffers from severe coughing, medications that clear the throat and benefit the voice can be used to alleviate the symptoms and reduce the patient's suffering. (Medication should be administered under the guidance of a doctor.)

Do the early symptoms of laryngeal cancer include coughing?

Throat cancer refers to malignant tumors that occur in the pharyngeal region. Clinically, it commonly manifests as vocal cord cancer, pyriform sinus cancer, and hypopharyngeal cancer. The causes are linked to long-term smoking, alcohol consumption, gastrointestinal dysfunction, acid reflux, irritations, and improper or excessive use of the voice leading to cellular mutations. In its early stages, patients generally experience persistent worsening hoarseness. Sometimes, patients may also suffer from irritative coughing, a foreign body sensation in the throat, obstruction feeling, and breathing difficulties. Patients need to undergo a detailed examination with an electronic laryngoscope at a hospital, which can reveal cauliflower-like neoplasms in any part of the pharynx. At this point, a local biopsy is necessary. If the biopsy confirms a malignant tumor in the pharyngeal region, local surgical removal is required, followed by relevant radiotherapy or chemotherapy.

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.
