Hello Heidi,

Welcome to The Oral Cancer Foundation. I'm sorry to hear of your Moms problems. You sound very educated about her condition.
It's a tough personal decision to make decideing to continue treatment or not. It's tough ay 55, I would imagime it's much tougher at 84. What Mark siad above may be true but the quality of life issues can be tough. She has survived for six years which is a great thing. I hope she makes the decision concidering all her options. I understand how she feels.

Best of Luck, Danny Boy
