When is radiotherapy recommended for tongue cancer?

The treatment plan depends on whether the cancer is on the mobile tongue or farther back near the base of the tongue. Scans and examination show its size, depth and nearby spread. The pathology report after surgery can identify involved margins or lymph-node disease, which may lead to radiation to the tongue area, neck, or both.

Radiotherapy can be used after surgery, as a main treatment in selected situations, or alongside medicines. The team balances tumour control with effects on swallowing, speech, taste, saliva and jaw health.

Before treatment, ask about dental review, nutrition, speech and swallowing assessment, and the exact area to be treated. Tell the team about loose teeth, dentures, jaw problems, smoking, medicines, or any previous radiation. A personalised mask and imaging help guide each session.

Report mouth soreness, ulcers, thick saliva, taste changes, reduced drinking, or trouble swallowing early. Mouth care, pain relief, dietary support and swallowing exercises can make treatment easier to manage. Keep follow-up visits so the team can check healing and function.

Call your treatment team promptly if you cannot swallow fluids, have worsening mouth or throat swelling, uncontrolled pain, fever, or signs of dehydration. Seek emergency help for severe breathing difficulty, choking, or sudden inability to manage saliva.

Where exactly is my tongue cancer, and what does the treatment aim to achieve? Are lymph nodes included in the radiation field? Will I need surgery or medicines as well? How will my teeth, swallowing, speech, taste and saliva be supported? What should I do if eating becomes difficult?
