It is definitely better in my opinion to be in remission, not well and still with cancer than to be in active stage with docs saying things like you have three months or six months to live. The problem lies in uncertainty. The docs were wrong about the three months and wrong about the six months so perhaps they are wrong about the remission.
Faith and belief in getting better seems to be a big part of the answer. My son Mark (48) with liver cancer mets from esophageal cancer told me recently that all through the worst days of treatment when he looked and felt his sickest, he never believed he would die. Now if he can keep on believing it.He still suffers many side effects of the chemo and radiation but he is able to do more with his life that I ever thought would be possible. Recent scuba diving is an example of this. He still does not have the energy that he needs to get on with his life. If you want to read about the experiences of my son google cancer the next adventure and I think you will get the link.
