1. What are the early symptoms of laryngeal cancer?
Early symptoms of laryngeal cancer vary by tumor location. Glottic cancer mainly presents with persistent hoarseness; persistence beyond two weeks warrants vigilance.
2. What causes laryngeal cancer?
The main risk factors for laryngeal cancer are long-term smoking and drinking, which synergistically increase risk. HPVHPV infection is associated with some laryngeal cancers, especially oropharyngeal cancer.
3. What types of laryngeal cancer surgery are available?
Surgery is selected according to tumor extent and location. Early glottic cancer may be treated with cordectomy or frontolateral partial laryngectomy. More extensive tumors may require vertical or horizontal partial laryngectomy.
4. What is minimally invasive treatment for laryngeal cancer?
Transoral laser microsurgery and robotic surgery are the main minimally invasive treatments for laryngeal cancer. Tumors are removed through the mouth without a neck incision, preserving laryngeal function.
5. How effective is radiotherapy for laryngeal cancer?
Radiotherapy alone for early laryngeal cancer is comparable to surgery in effectiveness and preserves voice, making it an important option for early glottic cancer. Radiotherapy can precisely irradiate the tumor,
6. How can voice be restored after total laryngectomy?
After total laryngectomy, patients lose their natural ability to produce voice,
7. What follow-up is needed after laryngeal cancer treatment?
Regular laryngoscopy is needed after treatment, every 1-3 months during the first two years, with longer intervals thereafter. Monitor voice changes, swallowing, and neck lumps.
