A prognosis is a cancer specialist's best estimate of how your disease will respond to treatment, and what your life expectancy may be. Some patients whose cancer is discovered in the early stages may only need minor treatment. Others with advanced cancer may have few treatment options, if any, or may have an aggressive cancer with a low survival rate.
Patients who receive the worst news may proceed with treatment anyway; others may refuse treatment. Whatever decision you make, consider the wishes of loved ones, and talk it over with your cancer care team.
