IMPORTANCE OF TUMOR MARKERS

• Some tumor markers are specific for a particular type of cancer, while others are seen in several cancer types. Most of the well-known markers may also be elevated in non-cancerous conditions. Consequently, tumor markers alone are not diagnostic for cancer.
• The importance of the tumor marker is to be able to screen for and diagnose cancer early, when it is the most treatable and before it has had a chance to grow and spread.
