Cancer is not a dead end. It may be tough but you can still come out of it with flying colors. You not only have to fight a physical and mental war but an emotional war as well. If you have a strong willpower you can overcome absolute everything. All you need to do is be positive and fight it. In simple terms let the doctors do their job and you do yours with a positive mindset.
Sometimes I feel that such people are special because God choose them for such a thing for which neither clear causes are known nor treatment just for the mere reason that they are the ones who could accept this challenge and can come out of it. There have been cases where even sportspersons like Yuvraj Singh and Lance Armstrong have been detected with the same and they have not only fought back but even got back to their respective profession.
Another important factor is the people around you; the patients don’t need sympathy but just motivation and positive environment around them. Sometimes a few encouraging words are enough for the person to boost up. I have personally felt that with positive thought and mindset you can directly won more than half the battle.
