Even though cancer is considered a deadly disease, as most other diseases, you must not be afraid, for God is with you. He is the healer of all our diseases, not only cancer.
I know you're wondering why I spelled cancer with a small "c." It is because God can conquer any disease. You just have to have faith in God our Creator; the one who made the heaven and earth.
So now that we know that we shouldn't just do anything to harm our bodies, we need to change our mind-set about what we eat, what we harbor in our minds, or what we allow in our emotions. We need to be forgiving and loving always; otherwise, challenges can cause unease and stress in our hearts and mind.
