Radiotherapy can treat a mixed population of normal cells and tumour cells, kill the tumour cells but leave the normal cells unharmed. See lip cancer example below.

  • Six months after Radiotherapy alone
  • No surgery was used
Close up – arrows defie the former tumor border – all the flesh above the arrows was inside the tumor. If surgery had been used all that normal tissue would have been sacrificed.
