What does tumor margin mean?

What is a margin? When breast cancer is surgically removed (during a surgical biopsy, lumpectomy or mastectomy), a rim of normal tissue surrounding the tumor is also removed. This rim is called a margin. Margins help show whether or not all of the tumor was removed.

Does benign tumor spreads from the original site?
