My mother who is 80 recently underwent surgery to remove half her tongue and half the floor of her mouth. 2 weeks later the surgeons informed us that she has hi grade cancer in her lower jaw. They gave her the option of either having reconstruction or Radiation. She opted for radiation because she didnt want to go thru another op. However I am worried for her due to her age. What can she expect from radiation and for me as her carer what can I do for her?
