What is the definition or description of: tumor surgery?

Tumor surgery: This is a general term. Tumor just means lump or mass, but is often used to describe cancer. A surgery to remove a tumor can be quite simple like removing a lipoma which is superficial all the way to a very complex surgery like the whipple which is used to remove tumors in the pancreas. Usually the mass and a margin of normal tissue is removed.

Tumor surgery: The details of tumor surgeries vary by organ and type of cancer. In some cancers, clean margins are the goal (cervical cancer). In other cancer, the goal of surgery is removal of all visible and palpable cancer (ovarian cancer).
