Do You Have Cancer? How the Question Gets Answered

More than one million Americans are diagnosed with cancer each year. This can happen in one of several different ways:

  • Sometimes the cancer is detected by accident, as a surprising finding discovered while having an exam for a different reason.
  • Sometimes cancer is identified in a cancer screening – a test designed to identify cancers in the earliest and most treatable stages.
  • Some patients have signs or symptoms that raise concern and lead them to a doctor and a series of tests to identify the cause.
  • And some patients who've already been diagnosed with cancer are closely monitored through regular exams and medical tests. These patients may be in remission; they may have a slow-growing cancer (such as prostate cancer) that requires "watchful waiting", or they may undergo tests on a regular basis to make sure there are no new cancer developments.
