Thriving at hope's edge daily can be traumatic for some nurses. But cancer patients can give your career more satisfaction than you ever imagined, far surpassing the demands placed on you emotionally. Metastatic cancer ravages a body physically, as well as mentally, muting the rainbow of life with shades of gray. But in every rainbow there is sunlight, which illuminates the colors. Oncology nurses are the sunlight which keeps the rainbow of life from being destroyed. If you are considering a specialty, think about what you could give to the millions of people who will face the diagnosis of cancer this year and for many years to come. Oncology nursing has taught me to have hope even in the worst situations. It has also given me hope that someday there will be a cure for cancer. But until that time comes, being part of a few of the lives affected by it will make my life richer than gold at the end of any rainbow ever could.
