That is a question I ask myself every time they start a new regimine of treatments. The pain, the cost, the anemia, the fevers, the anger, the depression, I often wonder if it is all worth it.
Then I look at my kids and I think that if I stop trying, I will lose the time I have with them. My wife died of colon cancer in '04 and it was a short fight (41 days) but I know how she wanted to hold on to the family-- no matter the pain. I am trying to be that strong. My fight has been 4 years, 4 rounds of chemo and I am in my 3rd round of radiation now. The doctors are still finding new mets. as it spreads even in treatment, but I keep trudging on...
I guess it is easier to follow their advice than have to make a hard decision all by myself.
Thanks for asking this, I was afraid to ask myself much less others. You helped me 'figure out' how I feel.
Good luck
