My dad is 72 years old and was just diagnosed with cancer in the tongue (complete right side) and floor of the mouth. The cancer has not yet spread. He is offered 60% success rate with surgery removing right side of tongue, floor of mouth, and lymph nodes. Radiation to follow surgery. Other option is 30% success with Chemo and Radiation 5 days a week for 6 to 8 weeks. If it fails, surgery to follow. He wanted me to try to find opinions from others and/or what he could expect from the treatments.
