What exactly is a tumor?

What causes a tumor?

In general, tumors occur when cells divide and grow excessively in the body. Normally, the body controls cell growth and division. New cells are created to replace older ones or to perform new functions. Cells that are damaged or no longer needed die to make room for healthy replacements.

How does a tumor feel?

The way a tumor feels depends on its size, location, type, stage, and other factors. A cancerous lump in the breast, for example, tends to feel firm or solid and might be fixed to underlying tissue. Such lumps are often painless but do produce pain in a small percentage of patients.

What do tumors do to the body?

Benign, or noncancerous, tumors do not spread to other parts of the body, and do not create new tumors. Malignant, or cancerous, tumors crowd out healthy cells, interfere with body functions, and draw nutrients from body tissues.
