I am almost one year post diagnosis, Stage II, One thing about this cancer is it is slow growing, so you have time to make a decision, explore all your options, get a second opinion, I was lucky in that I was able to be treated with just chemo and radiation( I say lucky because I didn't have surgery, but it's still hell). When I was going through treatment, there were moments I did not want to go on, I actually prayed for God to take me and put me out of my pain. But, now...I would actually go through it all again. I'm 8 months post treatment, I've had two biopsies that looked suspicious but thankfully were nothing. I think it's always worth it, especially when you have family, children, grandchildren. I cherish life to the fullest and would do anything to stay here. It certainly is a personal decision, but from what you say, I think it would be worth the treatment and the chance at a longer life. Good luck in whatever your decision. And don't worry about the burden you feel you will be to your family, I felt the same way and they actually thanked me for allowing them to take care of me (in the beginning i swore I would take care of myself, but I finally got to the point where I had to ask for help. I'm sure your family would feel grateful to be able to take care of you.
Good Luck
