How do doctors know if a tumor is benign?

Benign tumors often have a visual border of a protective sac that helps doctors diagnose them as benign. Your doctor may also order blood tests to check for the presence of cancer markers. In other cases, doctors will take a biopsy of the tumor to determine whether it's benign or malignant.

A benign tumor has distinct, smooth, regular borders. A malignant tumor has irregular borders and grows faster than a benign tumor. A malignant tumor can also spread to other parts of your body.
