philip rosoff, m .D., agrees, noting an emphasis in society on autonomous decision-making that doctors are often afraid of impinging upon. We've abandoned our roles as advisors and healers, says Rosoff, an associate professor of pediatric hematology oncology at Duke University School of Medicine and director of the Duke Hospital Clinical Ethics Program in Durham, N.C. We give patients this smorgasbord of options: A, B, C, and D then ask, what do you want to do? Instead of giving A, B, C, and D, and saying, 'this is what I would do.'

The death of rapidly dividing healthy cells weakens the body's immune system, putting a person at risk for infections and other health problems.

If the cancer has reached these nodes, it means that cancer cells may have spread to other parts of the body, including other lymph nodes and other organs, such as the bones, liver, or lungs. When cancer spreads from its original location to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. For example, if breast cancer spreads to the brain, the cancer cells in the brain are actually breast cancer cells. The disease is called metastatic breast cancer.
