Vocal cord cancer

Vocal Cord Cancer is a type of cancer that occurs in the vocal cords, which are part of the larynx or voice box. This form of cancer is also known as laryngeal cancer, specifically glottic cancer, as it affects the glottis, the part of the larynx that houses the vocal cords. Vocal cord cancer can disrupt normal voice function, leading to symptoms such as hoarseness, difficulty speaking, and in advanced stages, breathing difficulties.

Causes and Risk Factors

The exact cause of vocal cord cancer is not fully understood, but several risk factors have been identified. Prolonged exposure to tobacco smoke is the most significant risk factor. Other factors include excessive alcohol consumption, exposure to certain chemicals and environmental pollutants, and Human Papillomavirus (HPV) infection. A history of chronic laryngitis or voice overuse can also contribute to the development of this cancer.

Symptoms

Early symptoms of vocal cord cancer include a persistent hoarseness or changes in the voice. As the cancer progresses, individuals may experience difficulty swallowing, a sensation of a lump in the throat, unexplained weight loss, bad breath, and persistent coughing, sometimes with blood. Early detection is crucial for effective treatment.

Diagnosis

Diagnosis of vocal cord cancer typically involves a combination of physical examination, review of symptoms, and specialized tests. A laryngoscopy, which allows the doctor to view the vocal cords directly, is commonly used. Imaging tests such as MRI scans, CT scans, and X-rays may be employed to determine the extent of the cancer. A biopsy, where a small tissue sample is taken and examined for cancer cells, is essential for a definitive diagnosis.

Treatment

Treatment options for vocal cord cancer depend on the stage of the cancer, the patient's overall health, and personal preferences. Early-stage vocal cord cancer may be treated with radiation therapy, which aims to preserve the voice. Surgery is another option, ranging from minimally invasive procedures to remove small tumors to more extensive surgeries for advanced cancer. In some cases, partial or total removal of the larynx (laryngectomy) may be necessary. Chemotherapy may be used in conjunction with other treatments, especially in advanced stages.

Prognosis

The prognosis for vocal cord cancer varies depending on the stage at diagnosis and the treatment received. Early detection and treatment significantly improve the chances of a successful outcome and voice preservation. Regular follow-ups are essential to monitor for recurrence.

Prevention

Prevention of vocal cord cancer involves reducing exposure to known risk factors. Avoiding tobacco use, limiting alcohol consumption, protecting oneself from exposure to harmful chemicals, and seeking treatment for chronic laryngitis can help lower the risk. HPV vaccination is also recommended to prevent HPV-related cancers.
