In his 1971 state of the union address, President Nixon called for a cure to cancer.

Since then there has been $200 billion dollars spent and despite the research efforts put forth, cancer is responsible for 13% of all deaths and is predicted to overtake heart disease claiming more than a half million lives annually.

Why is this challenge proving to be so difficult? The answer lies in the individuality of our DNA. Cancer is a disease of our cells. When a normal cell divides, the cell’s DNA is copied more or less perfectly, however, each division brings about subtle and unique changes in the DNA. Although similar, one person’s cancerous cells are not exactly like someone else’s with the same “type” of cancer. The unpredictable nature of cancer cells makes broad cures elusive.
