Oral cancer treatment
The location and extent of a mouth cancer help determine treatment. Ask how the plan will affect speaking, chewing and swallowing.
These are general treatment options. Your team will confirm which treatments are suitable and where they are available. PMGH oncology clinical services are scheduled to begin in December 2026.

Surgery and recovery
Surgery is often a main treatment when mouth cancer can be removed. It may include nearby lymph nodes in the neck. Reconstruction may help restore appearance and function.
Pain, swelling and changes in speech or eating can occur. Ask about support with swallowing and nutrition. Some people need a feeding tube during recovery.
Radiotherapy and mouth care
Radiotherapy may follow surgery, be used when surgery is unsuitable, or help relieve symptoms. The team will explain its purpose in your plan.
Mouth soreness, painful swallowing, dry mouth and taste changes can occur. Later effects can include jaw stiffness and dental problems. Ask for dental assessment before treatment and a plan for mouth care and eating. Tell a dentist about previous head-and-neck radiotherapy before any dental procedure.
What happens during radiotherapyWhen Systemic Anti-Cancer Therapy (SACT) may be used
Chemotherapy may be combined with radiotherapy for selected cancers. Systemic Anti-Cancer Therapy (SACT) may also help control cancer that has returned or spread. The choice can include chemotherapy, immunotherapy or targeted treatment, depending on the cancer and available options.
Some SACT drugs can affect the kidneys, hearing or nerves. Ask which checks you need and report changes promptly.
