Q. My treatments for cancer aren't always easy. More and more, I am thinking negative thoughts, which only increases my anxiety. What can I do to calm my mind and help make my treatment sessions go more smoothly?

A.

We’ve all heard the saying, “We are what we eat.” No one disputes that since it’s apparent the food we put into our mouths replenishes cells and becomes our physical bodies. Less commonly heard is, “We are what we think.” This is because it is much less apparent what direct impact our thoughts play in our well being. Unlike food, which can be quantified and controlled, our thoughts are affected by external sources often outside our control including people, places and things. Now, the growing field of psychoneuroimmunology (PNI) shows that the mind and body are constantly communicating, back and forth.

If negative thoughts come up for you in managing your cancer, guided imagery exercises can help you counter them with positive thoughts, so the body can be more relaxed. One imagery exercise is called Creative Visualization, which is used in sports psychology, business and other areas where people confront challenges. It’s a simple technique that uses your imagination to envision an event as you would like it to happen.

Before receiving a chemotherapy treatment, you might take time to quietly sit and visualize how you would ideally like treatment to go. It helps to think about details such as what clothing you’re wearing, how the weather feels, or where you’ll be sitting or lying when you get your treatment.

During your treatment, you can continue to visualize the chemotherapy (or radiation or surgery) as it travels through your body and “confronts” the cancer cells. Use your imagination: employ super heroes (yourself or others), magic wands, or loved ones providing comfort, hope and strength to defeat the cancer. This technique can ease the mind’s tendency to worry and help you focus on “rallying” healthy cells and the immune system to defeat disease.

If you have difficulty coming up with your own Creative Visualization exercise, it might be easier to listen to a pre-recorded Creative Visualization exercise. You can find a large number of CDs and audiobooks on this subject by doing a search (using keywords “guided imagery” or “creative visualization”) at Amazon.com. Also, a good book on the topic is Creative Visualization: Use the Power of Your Imagination to Create What You Want in Your Life, by Shakti Gawain (New World Library Publishers).
