A tumor is a mass of cells.

The correct answer is:

- a mass of cells.

Explanation:
A tumor is a mass or abnormal growth of cells. It can occur in various parts of the body and can be either benign (non-cancerous) or malignant (cancerous). Tumors form as a result of uncontrolled cell division and growth. When cells divide and multiply in a controlled manner, it is a normal process for growth and repair. However, when this process is disrupted, the cells can continue to divide and accumulate to form a tumor. To understand what a tumor is, you need to know about cell division and growth.
