Calm your mind, your human self.  One way is by being grateful and give thanks for who and where you are as well as all the support you have been given.  Then try forgiving all the real and imagined wrongs that have hurt you.

Visualize all the negative thoughts and fears about your illness as a dark color.  See the darkness from the pain and suffering from the disease being pulled up and out of the body.  Continue with this until you feel your self relaxing into a meditative state.

Keeping mindful of your breath, breathe in comfort and breathe out tension.  Visualize your heart as a white and gold light.  Out from this light comes millions of smaller light bubbles that are being sent out to dissolve the dark cancer cells and transform them into Love and Light. Then release this love and light back to the universe out of the top of your head and onto the four winds. 

Remember to breath in and breath out.  Now visualize your heart as a green color pick a color green that brings you comfort.  Send out the green light bubbles to heal the damaged cells left after the treatment. This is necessary for balance in your body.

Again visualize the white and gold light.  Now send it through the body for strength and courage.  Slowly expand this light outside your physical body to form a shield or bubble of strength.
