Within our body there are seven major energy centers, called chakras. These spiritual centers are aligned along the spinal column and are related to certain organs in the physical body. When energy is out of balance or not flowing correctly in the spiritual centers of the body, it can manifest as different kinds of imbalances, eventually resulting in illness or imbalance in the corresponding organs. Since the breast is close to and associated with the heart chakra, breast cancer can be seen to be related to this chakra.
The heart chakra is the center of divine love, and the light of this chakra at spiritual levels is a beautiful rose-pink. The heart chakra is often likened to a rose—a twelve-petaled rose-colored center from which divine love flows.
There has been much written about the heart and the path of the heart. Even in our everyday language, the significance of the heart is seen: “Her heart is broken” or “It pains my heart to hear of all that she has been through” or “Get to the heart of the matter” or “Follow your heart and do what your heart tells you to do.” These are but a few of the many little phrases that tell us that we all know intuitively how important the heart is as a spiritual center. The heart is our most important spiritual center. There is a spiritual flame that burns in your heart; the light in your heart is greater than all of the darkness that is in the world. This is why the Bible says, “Greater is he that is in you, than he that is in the world.” 
The “he that is in you” is the spirit of the living God, the flame of life that is anchored within your heart. The Heart Chakra is associated with the color green or pink. This love center of our human energy system is often the focus in bringing about a healing. Thus, the words "Love Heals All" have great truth. Hurtful situations that can effect our emotional being are divorce or separation, grief through death, emotional abuse, abandonment, adultery. All of these are wounding to the heart chakra. Physical illnesses brought about by heartbreak require that an emotional healing occur along with the physical healing. Learning to love yourself is a powerful first step in securing a healthy fourth chakra. The "wounded child" resides in the heart chakra.  http://healing.about.com/cs/chakras/a/chakra4.htm
Prior to my own diagnosis, I had also experienced an extremely painful situation when my marriage ended as I began the completion of my art degree. I was alone in a new city without the resources or knowledge on how to cope, much less survive. I remember the pain in my chest being so severe I literally thought I was having a stroke or heart attack. This type of physical response to an emotional situation is common place and for those who do not understand the importance of dealing with emotional pain, the body can and does find a way to manifest and demands a “Call to Action!”
Western medicine has begun to look and embrace more holistic approaches to healing with consideration given to the true value and impact of our emotions on our physical and mental well being.
