  • Imaging tests. Computed Tomography (CT) scan, Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scan may be recommended by the specialist to know the extent of cancer and if it has spread.

  • Reconstructive surgery. In some cases of floor of the mouth cancer, reconstructive surgery may be performed to keep the function of the mouth based on the tumor size, location and cancer spread.
  • Rehabilitation. Rehabilitation may be needed after surgery or radiation therapy to restore the body’s function and basic needs through speech therapy, swallowing therapy, dietetics, physical therapy and occupational therapy.
