How effective is radiotherapy for nasopharyngeal cancer?

The nasopharynx sits behind the nose and close to the base of the skull, eyes, ears, throat and important nerves. Radiotherapy is planned from scans so the beam covers the cancer and, when needed, nearby lymph nodes. It may be combined with chemotherapy or other treatment when cancer has a greater risk of spreading. Doctors judge effectiveness by the treatment goal, examination and follow-up scans rather than by symptoms alone. Ear blockage, nasal symptoms or tiredness may change during treatment without showing whether the cancer has responded.

Discuss the planned treatment area, the role of chemotherapy and how your hearing, teeth, saliva and swallowing will be monitored. Tell the team about dental work, medicines and existing ear or eye problems. Keep hydration and nutrition plans in place, attend review visits and use the recommended mouth, skin and nasal care. Report new symptoms early so supportive treatment can be adjusted.

Seek prompt advice for inability to drink, repeated vomiting, severe mouth or throat pain, fever, unusual bleeding, worsening hearing or vision, or breathing difficulty. A sudden severe headache, seizure, fainting or new weakness needs emergency help.

What is the aim of radiotherapy in my case? Will lymph nodes be included? Why might chemotherapy be added? How will my hearing, eyes, teeth and swallowing be protected? What follow-up will show how treatment is working?
