Introduction

1. A sensation of a foreign body in the throat or pain during swallowing—these symptoms are often subtle at disease onset, making them easy to overlook by both patients and physicians. 2. Blood-tinged sputum—patients frequently notice streaks of blood in mucus or sputum following coughing. 3. Dyspnea—this may result directly from tracheal obstruction impairing respiration or from impaired clearance of tracheal secretions.

Pharyngeal and laryngeal cancer is an umbrella term encompassing nasopharyngeal carcinoma, oropharyngeal carcinoma, and laryngeal carcinoma. The hypopharynx—also known as the “lower pharynx”—is the most common site for hypopharyngeal cancers, particularly the piriform sinus; the posterior wall of the hypopharynx is the second most frequent location. Treatment options include radiotherapy alone, surgery alone, surgery combined with radiotherapy, chemotherapy, and immunotherapy. So, what are the early symptoms of pharyngeal and laryngeal cancer? Below, we address this question.

Early Symptoms of Pharyngeal and Laryngeal Cancer

1. Sensation of a foreign body in the throat or painful swallowing

These symptoms are characteristic of early-stage supraglottic pharyngeal and laryngeal cancer. However, tumors originating on the vocal cords may also cause a sensation of a foreign body or painful swallowing once they progress to intermediate or advanced stages. Such symptoms are often subtle at disease onset, making them easily overlooked by both patients and clinicians.

2. Blood-tinged sputum

Due to the presence of abundant abnormal neovascularization within the tumor, patients frequently notice blood streaks in mucus or sputum following coughing. This symptom is commonly observed in patients with supraglottic or subglottic tumors, as well as those with intermediate- to advanced-stage vocal cord tumors; early-stage vocal cord tumors typically do not cause bleeding.

3. Dyspnea (difficulty breathing)

When the primary tumor undergoes significant progression and increases substantially in size, it may directly obstruct the trachea, impairing respiration, or impede clearance of tracheobronchial secretions, thereby leading to dyspnea. This symptom generally occurs only in late-stage pharyngeal cancer.

4. Persistent hoarseness

Hoarseness is the most common early symptom of pharyngeal and laryngeal cancer. In most cases, pharyngeal cancer originates on the vocal cords; even very small vocal cord tumors can disrupt normal vocal cord vibration and result in hoarseness.

5. Otalgia (ear pain)

When pharyngeal cancer progresses to a certain extent and causes ulceration and severe inflammation in the pharynx, it may trigger referred (reflex) neuralgic pain. Early-stage vocal cord tumors rarely produce referred pain, which predominantly occurs in patients with intermediate- to advanced-stage supraglottic tumors. The most common manifestation of early pharyngeal and laryngeal cancer-related referred pain is ipsilateral otalgia.

The above outlines the early symptoms of pharyngeal and laryngeal cancer. We hope this information is helpful to you.

Why is chemotherapy required after major cancer surgeries?

In general, patients with cancers such as lung cancer, gastric cancer, and breast cancer often require chemotherapy after surgery due to surgical trauma and stress, decreased immune function, minimal residual disease, active cell proliferation, and increased potential for metastasis. If any discomfort occurs, seek timely medical evaluation and treatment at a正规 hospital. In daily life, it is important to maintain a balanced diet with adequate protein and vitamin intake, and to follow a regular sleep schedule, avoiding staying up late.
