For what ever kind of cancer that you may have, any doctor would agree that the best approach is to deal with this step-by-step.
Your life is for you to decide. Just like what I have mentioned above. Cancer is like being in the wild jungle. It would be your choice if you would entirely delegate your survival to your guide and follow everything that he would say and do. Or you may actively involve your self, learning as much about the cancer and creating a partnership in the decisions that has to be made.
Each one deals with cancer differently. If you get cancer and decided to join a support group, use herbs or take long walks along the beach, it is your choice. But for people you care about get cancer, they need to make their own decisions. You can offer suggestions, but if they choose a different path, it is usually best to support them.
